++==============================================================
++LuaTeX 1.08 2018-08-28
++==============================================================
++
++
++(1) This release is a prelude to 1.10, the next stable iteration of LuaTeX
++after version 1.00.
++
++(2) Lua 5.3 is now considered to be default and we might use 5.4 in version
++1.10. There are no real functional changed expected. You still need to rename
++the binary for 5.3!
++
++(3) Binary mode is no longer available in MPlib but it is still available in
++stand alone MetaPost. This simplifies compilation and reduces dependencies.
++
++(4) The dependency on Poppler for pdf image inclusion has been removed. We
++now use a small dedicated library written by Pawel Jakowski. We no longer
++need c++ compilers. We're in the process of making it behave well on all
++platforms. It has been tested on intel platforms.
++
++(5) We know that there can be some (alignment) issues with the arm platform
++but these are looked into. Therefore, later this year we will release 1.09.
++Version 1.10 is planned for TeXlive. We hope that ffi works ok on intel and
++arm platforms at that point.
++
++(6) There have been some extensions to the Lua libraries and some callbacks
++have been added. Also, a few new primitives have been introduced. The
++documentation mentions the stable extensions.
++
++(7) There are the usual bug fixes and cleanups but there have been no real
++fundamental changes in the API.
++
++

+-The |vinfo| fields in the entries of the down stack or the right stack
+-have six possible settings: |y_here| or |z_here| mean that the \.{DVI}
+-command refers to |y| or |z|, respectively (or to |w| or |x|, in the
+-case of horizontal motion); |yz_OK| means that the \.{DVI} command is
+-\\{down} (or \\{right}) but can be changed to either |y| or |z| (or
+-to either |w| or |x|); |y_OK| means that it is \\{down} and can be changed
+-to |y| but not |z|; |z_OK| is similar; and |d_fixed| means it must stay
+-\\{down}.
+-
+-The four settings |yz_OK|, |y_OK|, |z_OK|, |d_fixed| would not need to
+-be distinguished from each other if we were simply solving the
+-digit-subscripting problem mentioned above. But in \TeX's case there is
+-a complication because of the nested structure of |push| and |pop|
+-commands. Suppose we add parentheses to the digit-subscripting problem,
+-redefining hits so that $\delta_y\ldots \delta_y$ is a hit if all $y$'s between
+-the $\delta$'s are enclosed in properly nested parentheses, and if the
+-parenthesis level of the right-hand $\delta_y$ is deeper than or equal to
+-that of the left-hand one. Thus, `(' and `)' correspond to `|push|'
+-and `|pop|'. Now if we want to assign a subscript to the final 1 in the
+-sequence
+-$$2_y\,7_d\,1_d\,(\,8_z\,2_y\,8_z\,)\,1$$
+-we cannot change the previous $1_d$ to $1_y$, since that would invalidate
+-the $2_y\ldots2_y$ hit. But we can change it to $1_z$, scoring a hit
+-since the intervening $8_z$'s are enclosed in parentheses.

+-The actual distances by which we want to move might be computed as the
+-sum of several separate movements. For example, there might be several
+-glue nodes in succession, or we might want to move right by the width of
+-some box plus some amount of glue. More importantly, the baselineskip
+-distances are computed in terms of glue together with the depth and
+-height of adjacent boxes, and we want the \.{DVI} file to lump these
+-three quantities together into a single motion.
+-
+-Therefore, \TeX\ maintains two pairs of global variables: |dvi.h| and |dvi.v|
+-are the |h| and |v| coordinates corresponding to the commands actually
+-output to the \.{DVI} file, while |cur.h| and |cur.v| are the coordinates
+-corresponding to the current state of the output routines. Coordinate
+-changes will accumulate in |cur.h| and |cur.v| without being reflected
+-in the output, until such a change becomes necessary or desirable; we
+-can call the |movement| procedure whenever we want to make |dvi.h=pos.h|
+-or |dvi.v=pos.v|.
+-
+-The current font reflected in the \.{DVI} output is called |dvi_f|;
+-there is no need for a `\\{cur\_f}' variable.
+-
+-The depth of nesting of |hlist_out| and |vlist_out| is called |cur_s|;
+-this is essentially the depth of |push| commands in the \.{DVI} output.

++Free entries seem to be a relic of ancient times, completelly useless for us. To avoid parsing xref table twice,
++we waste some space on free entries by allocating one plane of refs for each section. Later on we slice sections,

++
++Subsequent refs gets number, version and offset. Other fields initialized when parsing PDF body.
++
++Having xref table loaded, we sort sections for future binary search (xref with objects count == 0 is considered invalid).
++
++Then we have to deal with the trailer dict. In general, to load objects and resolve references we need a complete chain
++of xrefs (not only the top). To load the previous xref, we need its offset, which is given in trailer. So we have to
++parse the trailer ignoring references, which might be unresolvable at this point (objects parser makes a dummy check
++for xref != NULL on refs resolving ppscan_obj(), which irritates me but I don't want a separate parser for trailer..).
++The same applies to xref streams, in which we have parse the trailer not having xref map at all. So the procedure is:
++
++  - load xref map, initialize references, make it ready to search
++  - parse trailer ignoring references
++  - get /Prev xref offset and load older xref (linked list via ->prev)
++  - sort all refs in all xrefs by offset
++  - parse refs in order resolving references in contained objects
++  - fix trailer references
++
++First created xref becomes a pdf->xref (top xref). We link that early to control offsets already read (insane loops?).

++Flate codec example provided at http://www.zlib.net/zpipe.c (http://www.zlib.net/zlib_how.html) uses the following scheme:
++- provide input data buffer
++- keep providing output until codec function uses it
++
++For encoder:
++
++  z->zalloc = z->zfree = z->zopaque = NULL;
++  deflateInit(z, compression_level);
++  do {
++    z->next_in = <input buffer>
++    z->avail_in = <input buffer bytes>
++    do {
++      z->next_out = <output buffer>
++      z->avail_out = <output buffer bytes>
++      deflate(z, flush);
++      // write obtained output from deflate
++    } while (z->avail_out == 0);
++    assert(z->avail_in == 0);
++  } while (flush != Z_FINISH);
++  deflateEnd(z);
++
++'z' is an internal codec state of type z_stream, 'flush' is either Z_NO_FLUSH or Z_FINISH at the end of data.
++deflate() ensures to consume the entire input if there are no obstackles to write an output. The inner loop
++provides an output space as long as it is used by deflate(). When deflate() wrote everything it could,
++it leaves z->avail_out > 0, which breaks the inner loop. At this point z->avail_in should also be zero.
++The example documentation claims that the return codes from deflate() doesn't really need to be checked,
++as checking z->avail_out for zero is enough.
++
++The scheme for decoder is pretty similar, but with substantial differences:
++- the end of stream is automatically found by decoder, so using Z_FINISH flag to indicate an end of stream
++  is not necessary, but if provided, it MUST be given only if the EOF marker actually occurs in the input chunk,
++  and subsequent calls to inflate() must consequently use Z_FINISH
++- calling inflate() as long as it uses the output buffer provided still works for decoder, but inflate()
++  does not ensure to consume the entire input, as it will read until end of stream marker
++- the return code from inflate() must be checked to ensure the proper reaction on invalid data stream and
++  end of stream signals
++- initialization must set an input buffer to NULL or to some existing chunk (the later helps zlib to perform
++  better on inflate(), but inflate() does the research on the first call anyway)
++
++  z->zalloc = z->zfree = z->zopaque = NULL;
++  z->next_in = NULL, z->avail_in = 0;
++  inflateInit(z);
++  do {
++    z->next_in = <input buffer>
++    z->avail_in = <input buffer bytes>
++    do {
++      z->next_out = <output buffer>
++      z->avail_out = <output buffer bytes>
++      status = inflate(z, flush);
++      // check return status
++      // write obtained output from inflate
++    } while (z->avail_out == 0);
++  } while (status != Z_STREAM_END);
++  inflateEnd(z);
++
++Our wrapper generally follows "prepare input, keep pomping output" scheme, but we need to support handler function
++breaks on IOFEMPTY and IOFFULL. For a consistent come back from those on subsequent calls to the handler function,
++we use 3 states:
++- FLATE_IN - get input, when got something then goto FALTE_OUT
++- FLATE_OUT - set z_stream buffers and keep writing output until enything to write, then goto FLATE_IN or FLATE_DONE
++- FLATE_DONE - we are done, no return from that state
++Distinction of FLATE_IN and FLATE_OUT states guarantees that we will not get more input until zlib consumes the stuff
++from the previous feed, possibly interrupted by IOFFULL return on filling the output buffer. This distinction is not
++critical, but makes the filter running according to the scheme described above. Note that we set zlib input buffer
++(z->next_in, z->avail_in) at the beginning of FLATE_OUT state. Also note that we always update our buffers according
++to updated avail_in / avail_out values, just after a call to inflate() / deflate(). So no matter what have happens
++between handler calls, zlib input buffer is in sync with ours.

++/* predictor filters; common for flate and lzw */
++
++#include "utilmem.h"
++#include "utillog.h"
++#include "utilfpred.h"
++
++/*
++Here we implement predictor filters used with flate and lzw compressions in PDF streams. The main idea of data prediction
++is to compute and output the differences between data records instead of this records. Adjacent pixels in images are usually
++similar, so differences between pixel values tends to be zero. And both Flate and LZW performs better when the input
++is rather smooth. Although a preliminary use of predictors is related to bitmap data, The actual need for predictor filter
++came from the fact that xref streams may also be predicted (usually with PNG up-predictor).
++
++PDF specification allows to use several predictor algorithms, specified by /Predictor key in /DecodeParms dictionary:
++
++   1 - no predictor (default)
++   2 - TIFF horizontal predictor
++  10 - PNG none predictor
++  11 - PNG sub predictor
++  12 - PNG up predictor
++  13 - PNG average predictor
++  14 - PNG paeth predictor
++
++All PNG predictors works on bytes, regardless the image color-depth. While encoding, every input data byte is decreased
++by the appropriate byte of the previous pixel. Even if the pixel does not fit a full byte, PNG predictors use an artificial
++pixel size rounded up to a full byte. PNG predictors utilizes previous (left) pixel, pixel above and previous to above
++pixel. In case of PNG, the type of the predictor is written on a dedicated byte on the beginning of every scanline. It
++means all predictor functions must maintain and information about left, above and left-above pixels.
++
++Despite the same differencing idea, TIFF predictors are different. The prediction process bases on pixel components,
++which are not necessarily bytes (component of a pixel is added/substracted from a relevant component of a previous
++pixel). In TIFF predictor 2, only the previous (the left) pixel is taken into account, there is no need to keep
++an information about other surrounding pixels. Also there is no expicit algorithm marker in data; the same prediction
++method is applied to all input rows.
++
++Not surprisingly, predictor encoders and decoders are pretty similar. Encoders take some input value and the previous
++input value (or 0 at the beginning of the scanline) and output a difference between them. Decoders takes an input value,
++previously decoded value (or zero) and outputs their sum. When encoding, the result is cast to the proper unsigned integer,
++when decoding, modulo 256 (or appropriate) is used, which makes encoding and decoding looseless.

++Some extra bits trickery is involved in TIFF predictor function, when components doesn't fit bytes boundary. In that case,
++an input is treated as an bits stream. Every input byte is "buffered" in a larger integer, as its lower bits (from right).
++Every output value is taken from its higher (left) bits. In a special case of bits-per-component equal 1, we buffer all
++pixel bits and use XOR to compute bits difference between pixels. I've excerpted that trick from poppler, but I'm not
++really sure if it works any better, especially when the number of components per pixel is 1. In that case we do a hard
++bit-by-bit work anyway.
++
++Predictor codecs state keeps a notion of surrounding pixels. PNG predictors uses left, up and upleft
++pixel data, while TIFF predictor (2) only needs the previous (left) pixel. Important to note that PNG
++predictors always work on bytes, no matter of color-depth (bits per component), while TIFF predictor
++works on pixel components, which not necessarily fits into a complete byte. However, for PNG predictor
++the size of a pixel still matters, because 'left' and 'upleft' refers to a corresponding pixel byte,
++not necessarily previous byte.
++
++In PNG prediction, we record every pixel byte (in decoded form) in state->rowsave. At the end of a scanline
++we copy state->rowsave to state->rowup, so that in the next scanline we can access up-pixel byte.
++Left pixel byte is accessed as state->rowsave (the byte recently stored or virtual left edge byte \0).
++Up-left pixel byte is accessed via state->rowup, but with state->pixelsize offset (same as left byte, possibly \0
++at the left edge of the row). Both state->rowup and state->rowsave has a safe span of pixelsize bytes on the left,
++that are permanently \0.

++pos (==buf). We can backup characters as long as there is a private space. If
++several calls to iof_backup() are followed by iof_get(), pos pointer
++increases in normal way and so the use of another iof_unget() works just fine
++by moving the position. Once we swallow all backup characters (when
++pos==end), backup handler restores the previous pointers.
++
++Obviously we assume that the character provided to iof_unget() is always the
++character just obtained from iof_get(). We CAN'T just overwrite the character

++/* lzw implementation for postscript/pdf filters
++# Notes on LZW
++
++# Encoder
++
++Initially the table contains 256 entires for single bytes. Encoder consumes
++input bytes trying to find the longest sequence stored so far in the table.
++Once it finds a sequence that is not present in the table, it outputs the table
++index of the longest sequence found (accumulated bytes except the last
++consumed) and pushes the new sequence (accumulated bytes including the last
++one) on the top of the table. The last taken byte is not yet written to the
++output, it becomes the beginning of the new sequence to accumulate. Initially,
++encoder outputs 9-bit codes. While the table grows, the number of bits for each
++code increases up to 12. In example, after adding a table entry of index 511 it
++is high time to switch to 10-bit bytes. /EarlyChange=true parameter in stream
++dictionary (both postscript and pdf) informs to increase the number of bits one
++code earlier then necessary. Looks pretty much like an early days bug that
++became a specification :) I have never found a PDF having /EarlyChange key
++specified anyway.
++
++Once the table becomes full (or when encoder decides it is worthy),
++a clear-table marker (code 256) purges the table and restores codes length to
++9. End-of-data marker (code 257) ends the stream. Conventionally, the beginning
++of the stream starts with clear-table marker.
++
++Postscript allows to provide a /UnitLength which determines the bit length of
++codes. The above description assumes UnitLength=8 (default). Allowed values are
++from 3 to 8. Different UnitLength also affects markers; clear-table is then
++2^UnitLength and end-of-data marker is 2^UnitLenth+1.
++
++Encoder outputs 9-12bit codes that are packed into bytes using high-bits-first
++scheme (default) or low-bits-scheme.
++
++PDF spec p. 73 (PS spec p. 135 gives an mistaken output sequence and so
++mistaken output bytes)

++
++# Decoder
++
++Decoder consumes input bytes transforming them to 9 to 12 bit codes. Initially
++it starts with 9bit codes and the table of 258 fixed codes (same as encoder).
++Basically, it interprets incoming codes as table indices (except 256 and 257
++markers) and it outputs byte sequences stored at given indices. It also
++upbuilds the table and changes the number of bits of codes when necessary. The
++key point on lzw is that both encoder and decoder builds the table
++synchronously.
++
++However, decoder needs some "knowledge" about how encoder works to be able to
++interpret a table index that it doesn't have so far. Look that the output from
++encoder in the example above. The first output code is conventional clear-table
++(256). Then comes a code 45. So far so good, decoder interprets code 45 as
++a (fixed) entry of the table, emitting byte 45. The next code is 258, which is
++should be interpreted as an index in the table. Oops, encoder doesn't have one
++yet. If that occurs, it means that encoder was able to output the new entry
++code just after adding it to a table. It means that
++
++  sequence_before + next_byte == next_byte + sequence_after
++
++This may happen not only for sequences like 45 45 45, but also symmetric series
++such as abcbabcba; abcb + a == a + bcba. Decoder must be aware of that and if
++it gets a code one larger than the top table index, it should create one on-fly
++by appending last entry sequence by the first by of the last entry.
++
++# UnitLength
++
++Postscript specification mentions about UnitLength parameter that can be used
++in LZW decoder (not allowed in encoder), with possible values from 3 to 8. This
++parameter determines the number of bits per code; form UnitLength + 1 to 12. It
++also determines which codes are used for clear-table marker (2^UnitLength) and
++end-of-data marker ((2^UnitLength)+1). Postscript specification says (page 134):
++
++"Initially, the code length is (UnitLength + 1) bits and the table contains only
++entries for the (2^UnitLength + 2) fixed codes. As encoding proceeds, entries are
++appended to the table, associating new codes with longer and longer input character
++sequences. The encoding and decoding filters maintain identical copies of
++this table."
++
++Later on page 136 Postscript specification says:
++
++"Data that has been LZW-encoded with a UnitLength less than 8 consists only of
++codes in the range 0 to 2^UnitLength - 1; consequently, the LZWDecode filter produces
++only codes in that range when read. UnitLength also affects the encoded
++representation, as described above."
++
++UnitLength (Postscript only) and LowBitsFirst are used only by decoder.
++EarlyChange should obviously be respected by both encoder and decoder. When
++table index reaches current bit length boundary (511, 1023, ...) it must react
++by increasing the number of bits of input code. But if the index reaches it
++maximum value (when the table is full), decoder is NOT supposed to clear the
++table. When the table is full, encoder must emit clear-table marker and it
++emits this code using 12 bits and reinitialize code bits after that. It means
++that, when the table is full, decoder should get one more 12-bit code (which
++should be clear-table marker) and actually clear the table and reinitialize
++code bits after that.
++
++# Clear-table vs last entry track (after tries and checks)
++
++It is also not quite clear what should actually happen when encoder gets a full
++table and it is supposed to emit clear-table marker. When it gets full, it
++means that it has just appended another entry to the table. And that happens
++only the input sequence collected so far plus the last byte is not present in
++the table. Encoder is supposed to output the table index of the present
++sequence and set the recent byte as a starting index of the new sequence to be
++collected. Even if it is time to clear the table, encoder is still supposed to
++keep the track of the last table entry. Decoder, however, must drop the track of the
++last code on clear-table.
++
++# Decoder table vs encoder table
++
++While decoding we need query lzw table by (subsequent) numeric codes and output
++character sequences stored in the table. While encoding we need to query the
++table on every input byte and fetch indices pointing to character sequences.
++Note that we never need to query the entire table for the longest sequence
++found so far. The encoder table do not need to access the longest character
++sequence at one piece. It is enough to keep the track of the current table
++index and the very next byte. We organize an encoder table into a search tree,
++where every node contains its table index (value) and last byte (key). Except
++initial tree content, every node is created on the base of the previous node
++and it conceptually point the sequence represented by that nodo consists of the
++previous node sequence plus the next byte.
++
++Every new node is a descendant of the node it has been derived from. Every node
++has a map (a search subtree) indexed by suffix byte value, pointing to
++descendants nodes. Every node also has binary tentackles (left/right fields)
++necessary to search the map (except initials, every node lives in a map of some
++ancestor node). The key point is that on every input byte we don't search the
++entire tree, but only the map of the current node children. The map tree is
++a simple binary tree with no balancing mechanism (not worthy to optimize an
++ephemeric structure that may be upbuilt more often then queried).
++
++In our implementation, decoder table requires  4069 entries (topmost index 4095).
++Encoder table, however, needs 4097 entries to handle the case when EarlyIndex
++parameter is 0 (I have never a chance to test that in practise). The node of index
++4096 might be added to a search tree, but its code is never emitted; the lookup
++is purged just after adding that node.

++  Independent implementation of MD5 (RFC 1321).
++
++  This code implements the MD5 Algorithm defined in RFC 1321, whose
++  text is available at
++	http://www.ietf.org/rfc/rfc1321.txt
++  The code is derived from the text of the RFC, including the test suite
++  (section A.5) but excluding the rest of Appendix A.  It does not include
++  any code or documentation that is identified in the RFC as being
++  copyrighted.

++  The original and principal author of md5.c is L. Peter Deutsch
++  <ghost@aladdin.com>.  Other authors are noted in the change history
++  that follows (in reverse chronological order):
++
++  2002-04-13 lpd Clarified derivation from RFC 1321; now handles byte order
++	either statically or dynamically; added missing #include <string.h>
++	in library.
++  2002-03-11 lpd Corrected argument list for main(), and added int return
++	type, in test program and T value program.
++  2002-02-21 lpd Added missing #include <stdio.h> in test program.
++  2000-07-03 lpd Patched to eliminate warnings about "constant is
++	unsigned in ANSI C, signed in traditional"; made test program
++	self-checking.
++  1999-11-04 lpd Edited comments slightly for automatic TOC extraction.
++  1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5).
++  1999-05-03 lpd Original version.

++    The 'zlib' compression library provides in-memory compression and
++  decompression functions, including integrity checks of the uncompressed data.
++  This version of the library supports only one compression method (deflation)
++  but other algorithms will be added later and will have the same stream
++  interface.
++
++    Compression can be done in a single step if the buffers are large enough,
++  or can be done by repeated calls of the compression function.  In the latter
++  case, the application must provide more input and/or consume the output
++  (providing more output space) before each call.
++
++    The compressed data format used by default by the in-memory functions is
++  the zlib format, which is a zlib wrapper documented in RFC 1950, wrapped
++  around a deflate stream, which is itself documented in RFC 1951.
++
++    The library also supports reading and writing files in gzip (.gz) format
++  with an interface similar to that of stdio using the functions that start
++  with "gz".  The gzip format is different from the zlib format.  gzip is a
++  gzip wrapper, documented in RFC 1952, wrapped around a deflate stream.
++
++    This library can optionally read and write gzip streams in memory as well.
++
++    The zlib format was designed to be compact and fast for use in memory
++  and on communications channels.  The gzip format was designed for single-
++  file compression on file systems, has a larger header than zlib to maintain
++  directory information, and uses a different, slower check method than zlib.
++
++    The library does not install any signal handler.  The decoder checks
++  the consistency of the compressed data, so the library should never crash
++  even in case of corrupted input.

++/*
++    deflate compresses as much data as possible, and stops when the input
++  buffer becomes empty or the output buffer becomes full.  It may introduce
++  some output latency (reading input without producing any output) except when
++  forced to flush.
++
++    The detailed semantics are as follows.  deflate performs one or both of the
++  following actions:
++
++  - Compress more input starting at next_in and update next_in and avail_in
++    accordingly.  If not all input can be processed (because there is not
++    enough room in the output buffer), next_in and avail_in are updated and
++    processing will resume at this point for the next call of deflate().
++
++  - Provide more output starting at next_out and update next_out and avail_out
++    accordingly.  This action is forced if the parameter flush is non zero.
++    Forcing flush frequently degrades the compression ratio, so this parameter
++    should be set only when necessary (in interactive applications).  Some
++    output may be provided even if flush is not set.
++
++    Before the call of deflate(), the application should ensure that at least
++  one of the actions is possible, by providing more input and/or consuming more
++  output, and updating avail_in or avail_out accordingly; avail_out should
++  never be zero before the call.  The application can consume the compressed
++  output when it wants, for example when the output buffer is full (avail_out
++  == 0), or after each call of deflate().  If deflate returns Z_OK and with
++  zero avail_out, it must be called again after making room in the output
++  buffer because there might be more output pending.
++
++    Normally the parameter flush is set to Z_NO_FLUSH, which allows deflate to
++  decide how much data to accumulate before producing output, in order to
++  maximize compression.
++
++    If the parameter flush is set to Z_SYNC_FLUSH, all pending output is
++  flushed to the output buffer and the output is aligned on a byte boundary, so
++  that the decompressor can get all input data available so far.  (In
++  particular avail_in is zero after the call if enough output space has been
++  provided before the call.) Flushing may degrade compression for some
++  compression algorithms and so it should be used only when necessary.  This
++  completes the current deflate block and follows it with an empty stored block
++  that is three bits plus filler bits to the next byte, followed by four bytes
++  (00 00 ff ff).
++
++    If flush is set to Z_PARTIAL_FLUSH, all pending output is flushed to the
++  output buffer, but the output is not aligned to a byte boundary.  All of the
++  input data so far will be available to the decompressor, as for Z_SYNC_FLUSH.
++  This completes the current deflate block and follows it with an empty fixed
++  codes block that is 10 bits long.  This assures that enough bytes are output
++  in order for the decompressor to finish the block before the empty fixed code
++  block.
++
++    If flush is set to Z_BLOCK, a deflate block is completed and emitted, as
++  for Z_SYNC_FLUSH, but the output is not aligned on a byte boundary, and up to
++  seven bits of the current block are held to be written as the next byte after
++  the next deflate block is completed.  In this case, the decompressor may not
++  be provided enough bits at this point in order to complete decompression of
++  the data provided so far to the compressor.  It may need to wait for the next
++  block to be emitted.  This is for advanced applications that need to control
++  the emission of deflate blocks.
++
++    If flush is set to Z_FULL_FLUSH, all output is flushed as with
++  Z_SYNC_FLUSH, and the compression state is reset so that decompression can
++  restart from this point if previous compressed data has been damaged or if
++  random access is desired.  Using Z_FULL_FLUSH too often can seriously degrade
++  compression.
++
++    If deflate returns with avail_out == 0, this function must be called again
++  with the same value of the flush parameter and more output space (updated
++  avail_out), until the flush is complete (deflate returns with non-zero
++  avail_out).  In the case of a Z_FULL_FLUSH or Z_SYNC_FLUSH, make sure that
++  avail_out is greater than six to avoid repeated flush markers due to
++  avail_out == 0 on return.
++
++    If the parameter flush is set to Z_FINISH, pending input is processed,
++  pending output is flushed and deflate returns with Z_STREAM_END if there was
++  enough output space; if deflate returns with Z_OK, this function must be
++  called again with Z_FINISH and more output space (updated avail_out) but no
++  more input data, until it returns with Z_STREAM_END or an error.  After
++  deflate has returned Z_STREAM_END, the only possible operations on the stream
++  are deflateReset or deflateEnd.
++
++    Z_FINISH can be used immediately after deflateInit if all the compression
++  is to be done in a single step.  In this case, avail_out must be at least the
++  value returned by deflateBound (see below).  If deflate does not return
++  Z_STREAM_END, then it must be called again as described above.
++
++    deflate() sets strm->adler to the adler32 checksum of all input read
++  so far (that is, total_in bytes).
++
++    deflate() may update strm->data_type if it can make a good guess about
++  the input data type (Z_BINARY or Z_TEXT).  In doubt, the data is considered
++  binary.  This field is only for information purposes and does not affect the
++  compression algorithm in any manner.
++
++    deflate() returns Z_OK if some progress has been made (more input
++  processed or more output produced), Z_STREAM_END if all input has been
++  consumed and all output has been produced (only when flush is set to
++  Z_FINISH), Z_STREAM_ERROR if the stream state was inconsistent (for example
++  if next_in or next_out was Z_NULL), Z_BUF_ERROR if no progress is possible
++  (for example avail_in or avail_out was zero).  Note that Z_BUF_ERROR is not

++    inflate decompresses as much data as possible, and stops when the input
++  buffer becomes empty or the output buffer becomes full.  It may introduce
++  some output latency (reading input without producing any output) except when
++  forced to flush.
++
++  The detailed semantics are as follows.  inflate performs one or both of the
++  following actions:
++
++  - Decompress more input starting at next_in and update next_in and avail_in
++    accordingly.  If not all input can be processed (because there is not
++    enough room in the output buffer), next_in is updated and processing will
++    resume at this point for the next call of inflate().
++
++  - Provide more output starting at next_out and update next_out and avail_out
++    accordingly.  inflate() provides as much output as possible, until there is
++    no more input data or no more space in the output buffer (see below about
++    the flush parameter).
++
++    Before the call of inflate(), the application should ensure that at least
++  one of the actions is possible, by providing more input and/or consuming more
++  output, and updating the next_* and avail_* values accordingly.  The
++  application can consume the uncompressed output when it wants, for example
++  when the output buffer is full (avail_out == 0), or after each call of
++  inflate().  If inflate returns Z_OK and with zero avail_out, it must be
++  called again after making room in the output buffer because there might be
++  more output pending.
++
++    The flush parameter of inflate() can be Z_NO_FLUSH, Z_SYNC_FLUSH, Z_FINISH,
++  Z_BLOCK, or Z_TREES.  Z_SYNC_FLUSH requests that inflate() flush as much
++  output as possible to the output buffer.  Z_BLOCK requests that inflate()
++  stop if and when it gets to the next deflate block boundary.  When decoding
++  the zlib or gzip format, this will cause inflate() to return immediately
++  after the header and before the first block.  When doing a raw inflate,
++  inflate() will go ahead and process the first block, and will return when it
++  gets to the end of that block, or when it runs out of data.
++
++    The Z_BLOCK option assists in appending to or combining deflate streams.
++  Also to assist in this, on return inflate() will set strm->data_type to the
++  number of unused bits in the last byte taken from strm->next_in, plus 64 if
++  inflate() is currently decoding the last block in the deflate stream, plus
++  128 if inflate() returned immediately after decoding an end-of-block code or
++  decoding the complete header up to just before the first byte of the deflate
++  stream.  The end-of-block will not be indicated until all of the uncompressed
++  data from that block has been written to strm->next_out.  The number of
++  unused bits may in general be greater than seven, except when bit 7 of
++  data_type is set, in which case the number of unused bits will be less than
++  eight.  data_type is set as noted here every time inflate() returns for all
++  flush options, and so can be used to determine the amount of currently
++  consumed input in bits.
++
++    The Z_TREES option behaves as Z_BLOCK does, but it also returns when the
++  end of each deflate block header is reached, before any actual data in that
++  block is decoded.  This allows the caller to determine the length of the
++  deflate block header for later use in random access within a deflate block.
++  256 is added to the value of strm->data_type when inflate() returns
++  immediately after reaching the end of the deflate block header.
++
++    inflate() should normally be called until it returns Z_STREAM_END or an
++  error.  However if all decompression is to be performed in a single step (a
++  single call of inflate), the parameter flush should be set to Z_FINISH.  In
++  this case all pending input is processed and all pending output is flushed;
++  avail_out must be large enough to hold all the uncompressed data.  (The size
++  of the uncompressed data may have been saved by the compressor for this
++  purpose.) The next operation on this stream must be inflateEnd to deallocate
++  the decompression state.  The use of Z_FINISH is never required, but can be
++  used to inform inflate that a faster approach may be used for the single
++  inflate() call.
++
++     In this implementation, inflate() always flushes as much output as
++  possible to the output buffer, and always uses the faster approach on the
++  first call.  So the only effect of the flush parameter in this implementation
++  is on the return value of inflate(), as noted below, or when it returns early
++  because Z_BLOCK or Z_TREES is used.
++
++     If a preset dictionary is needed after this call (see inflateSetDictionary
++  below), inflate sets strm->adler to the adler32 checksum of the dictionary
++  chosen by the compressor and returns Z_NEED_DICT; otherwise it sets
++  strm->adler to the adler32 checksum of all output produced so far (that is,
++  total_out bytes) and returns Z_OK, Z_STREAM_END or an error code as described
++  below.  At the end of the stream, inflate() checks that its computed adler32
++  checksum is equal to that saved by the compressor and returns Z_STREAM_END
++  only if the checksum is correct.
++
++    inflate() can decompress and check either zlib-wrapped or gzip-wrapped
++  deflate data.  The header type is detected automatically, if requested when
++  initializing with inflateInit2().  Any information contained in the gzip
++  header is not retained, so applications that need that information should
++  instead use raw inflate, see inflateInit2() below, or inflateBack() and
++  perform their own processing of the gzip header and trailer.
++
++    inflate() returns Z_OK if some progress has been made (more input processed
++  or more output produced), Z_STREAM_END if the end of the compressed data has
++  been reached and all uncompressed output has been produced, Z_NEED_DICT if a
++  preset dictionary is needed at this point, Z_DATA_ERROR if the input data was
++  corrupted (input stream not conforming to the zlib format or incorrect check
++  value), Z_STREAM_ERROR if the stream structure was inconsistent (for example
++  next_in or next_out was Z_NULL), Z_MEM_ERROR if there was not enough memory,
++  Z_BUF_ERROR if no progress is possible or if there was not enough room in the
++  output buffer when Z_FINISH is used.  Note that Z_BUF_ERROR is not fatal, and
++  inflate() can be called again with more input and more output space to
++  continue decompressing.  If Z_DATA_ERROR is returned, the application may
++  then call inflateSync() to look for a good compression block if a partial
++  recovery of the data is desired.

++
++     This is another version of deflateInit with more compression options.  The
++   fields next_in, zalloc, zfree and opaque must be initialized before by the
++   caller.
++
++     The method parameter is the compression method.  It must be Z_DEFLATED in
++   this version of the library.
++
++     The windowBits parameter is the base two logarithm of the window size
++   (the size of the history buffer).  It should be in the range 8..15 for this
++   version of the library.  Larger values of this parameter result in better
++   compression at the expense of memory usage.  The default value is 15 if
++   deflateInit is used instead.
++
++     windowBits can also be -8..-15 for raw deflate.  In this case, -windowBits
++   determines the window size.  deflate() will then generate raw deflate data
++   with no zlib header or trailer, and will not compute an adler32 check value.
++
++     windowBits can also be greater than 15 for optional gzip encoding.  Add
++   16 to windowBits to write a simple gzip header and trailer around the
++   compressed data instead of a zlib wrapper.  The gzip header will have no
++   file name, no extra data, no comment, no modification time (set to zero), no
++   header crc, and the operating system will be set to 255 (unknown).  If a
++   gzip stream is being written, strm->adler is a crc32 instead of an adler32.
++
++     The memLevel parameter specifies how much memory should be allocated
++   for the internal compression state.  memLevel=1 uses minimum memory but is
++   slow and reduces compression ratio; memLevel=9 uses maximum memory for
++   optimal speed.  The default value is 8.  See zconf.h for total memory usage
++   as a function of windowBits and memLevel.
++
++     The strategy parameter is used to tune the compression algorithm.  Use the
++   value Z_DEFAULT_STRATEGY for normal data, Z_FILTERED for data produced by a
++   filter (or predictor), Z_HUFFMAN_ONLY to force Huffman encoding only (no
++   string match), or Z_RLE to limit match distances to one (run-length
++   encoding).  Filtered data consists mostly of small values with a somewhat
++   random distribution.  In this case, the compression algorithm is tuned to
++   compress them better.  The effect of Z_FILTERED is to force more Huffman
++   coding and less string matching; it is somewhat intermediate between
++   Z_DEFAULT_STRATEGY and Z_HUFFMAN_ONLY.  Z_RLE is designed to be almost as
++   fast as Z_HUFFMAN_ONLY, but give better compression for PNG image data.  The
++   strategy parameter only affects the compression ratio but not the
++   correctness of the compressed output even if it is not set appropriately.
++   Z_FIXED prevents the use of dynamic Huffman codes, allowing for a simpler
++   decoder for special applications.
++
++     deflateInit2 returns Z_OK if success, Z_MEM_ERROR if there was not enough
++   memory, Z_STREAM_ERROR if any parameter is invalid (such as an invalid
++   method), or Z_VERSION_ERROR if the zlib library version (zlib_version) is
++   incompatible with the version assumed by the caller (ZLIB_VERSION).  msg is

++     Initializes the compression dictionary from the given byte sequence

++   of deflate.  The compressor and decompressor must use exactly the same
++   dictionary (see inflateSetDictionary).
++
++     The dictionary should consist of strings (byte sequences) that are likely
++   to be encountered later in the data to be compressed, with the most commonly
++   used strings preferably put towards the end of the dictionary.  Using a
++   dictionary is most useful when the data to be compressed is short and can be
++   predicted with good accuracy; the data can then be compressed better than
++   with the default empty dictionary.
++
++     Depending on the size of the compression data structures selected by
++   deflateInit or deflateInit2, a part of the dictionary may in effect be
++   discarded, for example if the dictionary is larger than the window size
++   provided in deflateInit or deflateInit2.  Thus the strings most likely to be
++   useful should be put at the end of the dictionary, not at the front.  In
++   addition, the current implementation of deflate will use at most the window
++   size minus 262 bytes of the provided dictionary.
++
++     Upon return of this function, strm->adler is set to the adler32 value
++   of the dictionary; the decompressor may later use this value to determine

++
++     The windowBits parameter is the base two logarithm of the maximum window
++   size (the size of the history buffer).  It should be in the range 8..15 for
++   this version of the library.  The default value is 15 if inflateInit is used
++   instead.  windowBits must be greater than or equal to the windowBits value
++   provided to deflateInit2() while compressing, or it must be equal to 15 if
++   deflateInit2() was not used.  If a compressed stream with a larger window
++   size is given as input, inflate() will return with the error code
++   Z_DATA_ERROR instead of trying to allocate a larger window.
++
++     windowBits can also be zero to request that inflate use the window size in

++
++     windowBits can also be -8..-15 for raw inflate.  In this case, -windowBits
++   determines the window size.  inflate() will then process raw deflate data,

++   looking for any check values for comparison at the end of the stream.  This
++   is for use with other formats that use the deflate compressed data format
++   such as zip.  Those formats provide their own check values.  If a custom
++   format is developed using the raw deflate format for compressed data, it is
++   recommended that a check value such as an adler32 or a crc32 be applied to
++   the uncompressed data as is done in the zlib, gzip, and zip formats.  For
++   most applications, the zlib format should be used as is.  Note that comments
++   above on the use in deflateInit2() applies to the magnitude of windowBits.
++

++   sliding window by simply making the window itself the output buffer.  This
++   function trusts the application to not change the output buffer passed by

++
++     inflateBackInit() must be called first to allocate the internal state
++   and to initialize the state with the user-provided window buffer.
++   inflateBack() may then be used multiple times to inflate a complete, raw
++   deflate stream with each call.  inflateBackEnd() is then called to free the
++   allocated state.
++
++     A raw deflate stream is one with no zlib or gzip header or trailer.
++   This routine would normally be used in a utility that reads zip or gzip
++   files and writes out uncompressed files.  The utility would decode the
++   header and process the trailer on its own, hence this routine expects only
++   the raw deflate stream to decompress.  This is different from the normal
++   behavior of inflate(), which expects either a zlib or gzip header and
++   trailer around the deflate stream.
++
++     inflateBack() uses two subroutines supplied by the caller that are then
++   called by inflateBack() for input and output.  inflateBack() calls those
++   routines until it reads a complete deflate stream and writes out all of the
++   uncompressed data, or until it encounters an error.  The function's
++   parameters and return types are defined above in the in_func and out_func
++   typedefs.  inflateBack() will call in(in_desc, &buf) which should return the
++   number of bytes of provided input, and a pointer to that input in buf.  If
++   there is no input available, in() must return zero--buf is ignored in that
++   case--and inflateBack() will return a buffer error.  inflateBack() will call
++   out(out_desc, buf, len) to write the uncompressed data buf[0..len-1].  out()
++   should return zero on success, or non-zero on failure.  If out() returns
++   non-zero, inflateBack() will return with an error.  Neither in() nor out()
++   are permitted to change the contents of the window provided to
++   inflateBackInit(), which is also the buffer that out() uses to write from.
++   The length written by out() will be at most the window size.  Any non-zero
++   amount of input may be provided by in().
++
++     For convenience, inflateBack() can be provided input on the first call by
++   setting strm->next_in and strm->avail_in.  If that input is exhausted, then
++   in() will be called.  Therefore strm->next_in must be initialized before
++   calling inflateBack().  If strm->next_in is Z_NULL, then in() will be called
++   immediately for input.  If strm->next_in is not Z_NULL, then strm->avail_in
++   must also be initialized, and then if strm->avail_in is not zero, input will
++   initially be taken from strm->next_in[0 ..  strm->avail_in - 1].
++
++     The in_desc and out_desc parameters of inflateBack() is passed as the
++   first parameter of in() and out() respectively when they are called.  These
++   descriptors can be optionally used to pass any information that the caller-
++   supplied in() and out() functions need to do their job.
++
++     On return, inflateBack() will set strm->next_in and strm->avail_in to
++   pass back any unused input that was provided by the last in() call.  The

++
++The most important output produced by a run of \TeX\ is the ``device
++independent'' (\.{DVI}) file that specifies where characters and rules are to
++appear on printed pages. The form of these files was designed by David R. Fuchs
++in 1979. Almost any reasonable typesetting device can be driven by a program that
++takes \.{DVI} files as input, and dozens of such \.{DVI}-to-whatever programs
++have been written. Thus, it is possible to print the output of \TeX\ on many
++different kinds of equipment, using \TeX\ as a device-independent ``front end.''
++
++A \.{DVI} file is a stream of 8-bit bytes, which may be regarded as a series of
++commands in a machine-like language. The first byte of each command is the
++operation code, and this code is followed by zero or more bytes that provide
++parameters to the command. The parameters themselves may consist of several
++consecutive bytes; for example, the `|set_rule|' command has two parameters, each
++of which is four bytes long. Parameters are usually regarded as nonnegative
++integers; but four-byte-long parameters, and shorter parameters that denote
++distances, can be either positive or negative. Such parameters are given in two's
++complement notation. For example, a two-byte-long distance parameter has a value
++between $-2^{15}$ and $2^{15}-1$. As in \.{TFM} files, numbers that occupy more
++than one byte position appear in BigEndian order.
++
++A \.{DVI} file consists of a ``preamble,'' followed by a sequence of one or more
++``pages,'' followed by a ``postamble.'' The preamble is simply a |pre| command,
++with its parameters that define the dimensions used in the file; this must come
++first. Each ``page'' consists of a |bop| command, followed by any number of other
++commands that tell where characters are to be placed on a physical page, followed
++by an |eop| command. The pages appear in the order that \TeX\ generated them. If
++we ignore |nop| commands and \\{fnt\_def} commands (which are allowed between any
++two commands in the file), each |eop| command is immediately followed by a |bop|
++command, or by a |post| command; in the latter case, there are no more pages in
++the file, and the remaining bytes form the postamble. Further details about the
++postamble will be explained later.
++
++Some parameters in \.{DVI} commands are ``pointers.'' These are four-byte
++quantities that give the location number of some other byte in the file; the
++first byte is number~0, then comes number~1, and so on. For example, one of the
++parameters of a |bop| command points to the previous |bop|; this makes it
++feasible to read the pages in backwards order, in case the results are being
++directed to a device that stacks its output face up. Suppose the preamble of a
++\.{DVI} file occupies bytes 0 to 99. Now if the first page occupies bytes 100 to
++999, say, and if the second page occupies bytes 1000 to 1999, then the |bop| that
++starts in byte 1000 points to 100 and the |bop| that starts in byte 2000 points
++to 1000. (The very first |bop|, i.e., the one starting in byte 100, has a pointer
++of~$-1$.)
++
++The \.{DVI} format is intended to be both compact and easily interpreted by a
++machine. Compactness is achieved by making most of the information implicit
++instead of explicit. When a \.{DVI}-reading program reads the commands for a
++page, it keeps track of several quantities: (a)~The current font |f| is an
++integer; this value is changed only by \\{fnt} and \\{fnt\_num} commands. (b)~The
++current position on the page is given by two numbers called the horizontal and
++vertical coordinates, |h| and |v|. Both coordinates are zero at the upper left
++corner of the page; moving to the right corresponds to increasing the horizontal
++coordinate, and moving down corresponds to increasing the vertical coordinate.
++Thus, the coordinates are essentially Cartesian, except that vertical directions
++are flipped; the Cartesian version of |(h,v)| would be |(h,-v)|. (c)~The current
++spacing amounts are given by four numbers |w|, |x|, |y|, and |z|, where |w|
++and~|x| are used for horizontal spacing and where |y| and~|z| are used for
++vertical spacing. (d)~There is a stack containing |(h,v,w,x,y,z)| values; the
++\.{DVI} commands |push| and |pop| are used to change the current level of
++operation. Note that the current font~|f| is not pushed and popped; the stack
++contains only information about positioning.
++
++The values of |h|, |v|, |w|, |x|, |y|, and |z| are signed integers having up to
++32 bits, including the sign. Since they represent physical distances, there is a
++small unit of measurement such that increasing |h| by~1 means moving a certain
++tiny distance to the right. The actual unit of measurement is variable, as
++explained below; \TeX\ sets things up so that its \.{DVI} output is in sp units,
++i.e., scaled points, in agreement with all the |scaled| dimensions in \TeX's data
++structures.
++
++Here is a list of all the commands that may appear in a \.{DVI} file. Each
++command is specified by its symbolic name (e.g., |bop|), its opcode byte (e.g.,
++139), and its parameters (if any). The parameters are followed by a bracketed
++number telling how many bytes they occupy; for example, `|p[4]|' means that
++parameter |p| is four bytes long.
++
++\startitemize
++
++\startitem
++    |set_char_0| 0. Typeset character number~0 from font~|f| such that the
++    reference point of the character is at |(h,v)|. Then increase |h| by the
++    width of that character. Note that a character may have zero or negative
++    width, so one cannot be sure that |h| will advance after this command; but
++    |h| usually does increase.
++\stopitem
++
++\startitem
++    \\{set\_char\_1} through \\{set\_char\_127} (opcodes 1 to 127).
++    Do the operations of |set_char_0|; but use the character whose number
++    matches the opcode, instead of character~0.
++\stopitem
++
++\startitem
++    |set1| 128 |c[1]|. Same as |set_char_0|, except that character number~|c| is
++    typeset. \TeX82 uses this command for characters in the range |128<=c<256|.
++\stopitem
++
++\startitem
++    |set2| 129 |c[2]|. Same as |set1|, except that |c|~is two bytes long, so it
++    is in the range |0<=c<65536|. \TeX82 never uses this command, but it should
++    come in handy for extensions of \TeX\ that deal with oriental languages.
++\stopitem
++
++\startitem
++    |set3| 130 |c[3]|. Same as |set1|, except that |c|~is three bytes long, so it
++    can be as large as $2^{24}-1$. Not even the Chinese language has this many
++    characters, but this command might prove useful in some yet unforeseen
++    extension.
++\stopitem
++
++\startitem
++    |set4| 131 |c[4]|. Same as |set1|, except that |c|~is four bytes long.
++    Imagine that.
++\stopitem
++
++\startitem
++    |set_rule| 132 |a[4]| |b[4]|. Typeset a solid black rectangle of height~|a|
++    and width~|b|, with its bottom left corner at |(h,v)|. Then set |h:=h+b|. If
++    either |a<=0| or |b<=0|, nothing should be typeset. Note that if |b<0|, the
++    value of |h| will decrease even though nothing else happens. See below for
++    details about how to typeset rules so that consistency with \MF\ is
++    guaranteed.
++\stopitem
++
++\startitem
++    |put1| 133 |c[1]|. Typeset character number~|c| from font~|f| such that the
++    reference point of the character is at |(h,v)|. (The `put' commands are
++    exactly like the `set' commands, except that they simply put out a character
++    or a rule without moving the reference point afterwards.)
++\stopitem
++
++\startitem
++    |put2| 134 |c[2]|. Same as |set2|, except that |h| is not changed.
++\stopitem
++
++\startitem
++    |put3| 135 |c[3]|. Same as |set3|, except that |h| is not changed.
++\stopitem
++
++\startitem
++    |put4| 136 |c[4]|. Same as |set4|, except that |h| is not changed.
++\stopitem
++
++\startitem
++    |put_rule| 137 |a[4]| |b[4]|. Same as |set_rule|, except that |h| is not
++    changed.
++\stopitem
++
++\startitem
++    |nop| 138. No operation, do nothing. Any number of |nop|'s may occur between
++    \.{DVI} commands, but a |nop| cannot be inserted between a command and its
++    parameters or between two parameters.
++\stopitem
++
++\startitem
++    |bop| 139 $c_0[4]$ $c_1[4]$ $\ldots$ $c_9[4]$ $p[4]$. Beginning of a page:
++    Set |(h,v,w,x,y,z):=(0,0,0,0,0,0)| and set the stack empty. Set the current
++    font |f| to an undefined value. The ten $c_i$ parameters hold the values of
++    \.{\\count0} $\ldots$ \.{\\count9} in \TeX\ at the time \.{\\shipout} was
++    invoked for this page; they can be used to identify pages, if a user wants to
++    print only part of a \.{DVI} file. The parameter |p| points to the previous
++    |bop| in the file; the first |bop| has $p=-1$.
++\stopitem
++
++\startitem
++    |eop| 140. End of page: Print what you have read since the previous |bop|. At
++    this point the stack should be empty. (The \.{DVI}-reading programs that
++    drive most output devices will have kept a buffer of the material that
++    appears on the page that has just ended. This material is largely, but not
++    entirely, in order by |v| coordinate and (for fixed |v|) by |h|~coordinate;
++    so it usually needs to be sorted into some order that is appropriate for the
++    device in question.)
++\stopitem
++
++\startitem
++    |push| 141. Push the current values of |(h,v,w,x,y,z)| onto the top of the
++    stack; do not change any of these values. Note that |f| is not pushed.
++\stopitem
++
++\startitem
++    |pop| 142. Pop the top six values off of the stack and assign them
++    respectively to |(h,v,w,x,y,z)|. The number of pops should never exceed the
++    number of pushes, since it would be highly embarrassing if the stack were
++    empty at the time of a |pop| command.
++
++\startitem
++    |right1| 143 |b[1]|. Set |h:=h+b|, i.e., move right |b| units. The parameter
++    is a signed number in two's complement notation, |-128<=b<128|; if |b<0|, the
++    reference point moves left.
++\stopitem
++
++\startitem
++    |right2| 144 |b[2]|. Same as |right1|, except that |b| is a two-byte quantity
++    in the range |-32768<=b<32768|.
++\stopitem
++
++\startitem
++    |right3| 145 |b[3]|. Same as |right1|, except that |b| is a three-byte
++    quantity in the range |@t$-2^{23}$@><=b<@t$2^{23}$@>|.
++\stopitem
++
++\startitem
++    |right4| 146 |b[4]|. Same as |right1|, except that |b| is a four-byte
++    quantity in the range |@t$-2^{31}$@><=b<@t$2^{31}$@>|.
++\stopitem
++
++\startitem
++    |w0| 147. Set |h:=h+w|; i.e., move right |w| units. With luck, this
++    parameterless command will usually suffice, because the same kind of motion
++    will occur several times in succession; the following commands explain how
++    |w| gets particular values.
++\stopitem
++
++\startitem
++    |w1| 148 |b[1]|. Set |w:=b| and |h:=h+b|. The value of |b| is a signed
++    quantity in two's complement notation, |-128<=b<128|. This command changes
++    the current |w|~spacing and moves right by |b|.
++\stopitem
++
++\startitem
++    |w2| 149 |b[2]|. Same as |w1|, but |b| is two bytes long, |-32768<=b<32768|.
++\stopitem
++
++\startitem
++    |w3| 150 |b[3]|. Same as |w1|, but |b| is three bytes long,
++    |@t$-2^{23}$@><=b<@t$2^{23}$@>|.
++\stopitem
++
++\startitem
++    |w4| 151 |b[4]|. Same as |w1|, but |b| is four bytes long,
++    |@t$-2^{31}$@><=b<@t$2^{31}$@>|.
++\stopitem
++
++\startitem
++    |x0| 152. Set |h:=h+x|; i.e., move right |x| units. The `|x|' commands are
++    like the `|w|' commands except that they involve |x| instead of |w|.
++\stopitem
++
++\startitem
++    |x1| 153 |b[1]|. Set |x:=b| and |h:=h+b|. The value of |b| is a signed
++    quantity in two's complement notation, |-128<=b<128|. This command changes
++    the current |x|~spacing and moves right by |b|.
++\stopitem
++

++    |x2| 154 |b[2]|. Same as |x1|, but |b| is two bytes long, |-32768<=b<32768|.
++\stopitem

++
++The preamble contains basic information about the file as a whole. As stated
++above, there are six parameters: $$\hbox{|i[1]| |num[4]| |den[4]|
++|mag[4]| |k[1]| |x[k]|.}$$ The |i| byte identifies \.{DVI} format;
++currently this byte is always set to~2. (The value |i=3| is currently used for an
++extended format that allows a mixture of right-to-left and left-to-right
++typesetting. Some day we will set |i=4|, when \.{DVI} format makes another
++incompatible change---perhaps in the year 2048.)
++
++The next two parameters, |num| and |den|, are positive integers that define the
++units of measurement; they are the numerator and denominator of a fraction by
++which all dimensions in the \.{DVI} file could be multiplied in order to get
++lengths in units of $10^{-7}$ meters. Since $\rm 7227{pt} = 254{cm}$, and since
++\TeX\ works with scaled points where there are $2^{16}$ sp in a point, \TeX\ sets
++$|num|/|den|=(254\cdot10^5)/(7227\cdot2^{16})=25400000/473628672$.
++
++The |mag| parameter is what \TeX\ calls \.{\\mag}, i.e., 1000 times the desired
++magnification. The actual fraction by which dimensions are multiplied is
++therefore $|mag|\cdot|num|/1000|den|$. Note that if a \TeX\ source document does
++not call for any `\.{true}' dimensions, and if you change it only by specifying a
++different \.{\\mag} setting, the \.{DVI} file that \TeX\ creates will be
++completely unchanged except for the value of |mag| in the preamble and postamble.
++(Fancy \.{DVI}-reading programs allow users to override the |mag|~setting when a
++\.{DVI} file is being printed.)
++
++Finally, |k| and |x| allow the \.{DVI} writer to include a comment, which is not
++interpreted further. The length of comment |x| is |k|, where |0<=k<256|.
++
++The next macro identifies the kind of \.{DVI} files described here.
++
++*/
++
++#define id_byte 2
++
++/*tex
++
++Font definitions for a given font number |k| contain further parameters
++$$\hbox{|c[4]| |s[4]| |d[4]| |a[1]| |l[1]| |n[a+l]|.}$$ The four-byte value |c|
++is the check sum that \TeX\ found in the \.{TFM} file for this font; |c| should
++match the check sum of the font found by programs that read this \.{DVI} file.
++
++Parameter |s| contains a fixed-point scale factor that is applied to the
++character widths in font |k|; font dimensions in \.{TFM} files and other font
++files are relative to this quantity, which is called the ``at size'' elsewhere in
++this documentation. The value of |s| is always positive and less than $2^{27}$.
++It is given in the same units as the other \.{DVI} dimensions, i.e., in sp when
++\TeX82 has made the file. Parameter |d| is similar to |s|; it is the ``design
++size,'' and (like~|s|) it is given in \.{DVI} units. Thus, font |k| is to be used
++at $|mag|\cdot s/1000d$ times its normal size.
++
++The remaining part of a font definition gives the external name of the font,
++which is an ASCII string of length |a+l|. The number |a| is the length of the
++``area'' or directory, and |l| is the length of the font name itself; the
++standard local system font area is supposed to be used when |a=0|. The |n| field
++contains the area in its first |a| bytes.
++
++Font definitions must appear before the first use of a particular font number.
++Once font |k| is defined, it must not be defined again; however, we
++shall see below that font definitions appear in the postamble as well as
++in the pages, so in this sense each font number is defined exactly twice,
++if at all. Like |nop| commands, font definitions can
++appear before the first |bop|, or between an |eop| and a |bop|.
++
++Sometimes it is desirable to make horizontal or vertical rules line up precisely
++with certain features in characters of a font. It is possible to guarantee the
++correct matching between \.{DVI} output and the characters generated by \MF\ by
++adhering to the following principles: (1)~The \MF\ characters should be
++positioned so that a bottom edge or left edge that is supposed to line up with
++the bottom or left edge of a rule appears at the reference point, i.e., in row~0
++and column~0 of the \MF\ raster. This ensures that the position of the rule will
++not be rounded differently when the pixel size is not a perfect multiple of the
++units of measurement in the \.{DVI} file. (2)~A typeset rule of height $a>0$ and
++width $b>0$ should be equivalent to a \MF-generated character having black pixels
++in precisely those raster positions whose \MF\ coordinates satisfy
++|0<=x<@t$\alpha$@>b| and |0<=y<@t$\alpha$@>a|, where $\alpha$ is the number of
++pixels per \.{DVI} unit.
++
++The last page in a \.{DVI} file is followed by `|post|'; this command introduces
++the postamble, which summarizes important facts that \TeX\ has accumulated about
++the file, making it possible to print subsets of the data with reasonable
++efficiency. The postamble has the form
++
++$$\vbox{\halign{\hbox{#\hfil}\cr
++  |post| |p[4]| |num[4]| |den[4]| |mag[4]| |l[4]| |u[4]| |s[2]| |t[2]|\cr
++  $\langle\,$font definitions$\,\rangle$\cr
++  |post_post| |q[4]| |i[1]| 223's$[{\G}4]$\cr}}$$
++
++Here |p| is a pointer to the final |bop| in the file. The next three parameters,
++|num|, |den|, and |mag|, are duplicates of the quantities that appeared in the
++preamble.
++
++Parameters |l| and |u| give respectively the height-plus-depth of the tallest
++page and the width of the widest page, in the same units as other dimensions of
++the file. These numbers might be used by a \.{DVI}-reading program to position
++individual ``pages'' on large sheets of film or paper; however, the standard
++convention for output on normal size paper is to position each page so that the
++upper left-hand corner is exactly one inch from the left and the top. Experience
++has shown that it is unwise to design \.{DVI}-to-printer software that attempts
++cleverly to center the output; a fixed position of the upper left corner is
++easiest for users to understand and to work with. Therefore |l| and~|u| are often
++ignored. Parameter |s| is the maximum stack depth (i.e., the largest excess of
++
++|push| commands over |pop| commands) needed to process this file. Then comes |t|,
++the total number of pages (|bop| commands) present.
++
++The postamble continues with font definitions, which are any number of
++\\{fnt\_def} commands as described above, possibly interspersed with |nop|
++commands. Each font number that is used in the \.{DVI} file must be defined
++exactly twice: Once before it is first selected by a \\{fnt} command, and once in
++the postamble.
++
++The last part of the postamble, following the |post_post| byte that signifies the
++end of the font definitions, contains |q|, a pointer to the |post| command that
++started the postamble. An identification byte, |i|, comes next; this currently
++equals~2, as in the preamble.
++
++The |i| byte is followed by four or more bytes that are all equal to the decimal
++number 223 (i.e., '337 in octal). \TeX\ puts out four to seven of these trailing
++bytes, until the total length of the file is a multiple of four bytes, since this
++works out best on machines that pack four bytes per word; but any number of 223's
++is allowed, as long as there are at least four of them. In effect, 223 is a sort
++of signature that is added at the very end.
++
++This curious way to finish off a \.{DVI} file makes it feasible for
++\.{DVI}-reading programs to find the postamble first, on most computers, even
++though \TeX\ wants to write the postamble last. Most operating systems permit
++random access to individual words or bytes of a file, so the \.{DVI} reader can
++start at the end and skip backwards over the 223's until finding the
++identification byte. Then it can back up four bytes, read |q|, and move to byte
++|q| of the file. This byte should, of course, contain the value 248 (|post|); now
++the postamble can be read, so the \.{DVI} reader can discover all the information
++needed for typesetting the pages. Note that it is also possible to skip through
++the \.{DVI} file at reasonably high speed to locate a particular page, if that
++proves desirable. This saves a lot of time, since \.{DVI} files used in
++production jobs tend to be large.
++
++Unfortunately, however, standard \PASCAL\ does not include the ability to access
++a random position in a file, or even to determine the length of a file. Almost
++all systems nowadays provide the necessary capabilities, so \.{DVI} format has
++been designed to work most efficiently with modern operating systems. But if
++\.{DVI} files have to be processed under the restrictions of standard \PASCAL,
++one can simply read them from front to back, since the necessary header
++information is present in the preamble and in the font definitions. (The |l| and
++|u| and |s| and |t| parameters, which appear only in the postamble, are
++``frills'' that are handy but not absolutely necessary.)
++
++After considering \TeX's eyes and stomach, we come now to the bowels.
++
++The |ship_out| procedure is given a pointer to a box; its mission is to describe
++that box in \.{DVI} form, outputting a ``page'' to |dvi_file|. The \.{DVI}
++coordinates $(h,v)=(0,0)$ should correspond to the upper left corner of the box
++being shipped.
++
++Since boxes can be inside of boxes inside of boxes, the main work of |ship_out|
++is done by two mutually recursive routines, |hlist_out| and |vlist_out|, which
++traverse the hlists and vlists inside of horizontal and vertical boxes.
++
++As individual pages are being processed, we need to accumulate information about
++the entire set of pages, since such statistics must be reported in the postamble.
++The global variables |total_pages|, |max_v|, |max_h|, |max_push|, and |last_bop|
++are used to record this information.
++
++The variable |doing_leaders| is |true| while leaders are being output. The
++variable |dead_cycles| contains the number of times an output routine has been
++initiated since the last |ship_out|.
++
++A few additional global variables are also defined here for use in |vlist_out|
++and |hlist_out|. They could have been local variables, but that would waste stack
++space when boxes are deeply nested, since the values of these variables are not
++needed during recursive calls.

++
++The \.{DVI} bytes are output to a buffer instead of being written directly to the
++output file. This makes it possible to reduce the overhead of subroutine calls,
++thereby measurably speeding up the computation, since output of \.{DVI} bytes is
++part of \TeX's inner loop. And it has another advantage as well, since we can
++change instructions in the buffer in order to make the output more compact. For
++example, a `|down2|' command can be changed to a `|y2|', thereby making a
++subsequent `|y0|' command possible, saving two bytes.
++
++The output buffer is divided into two parts of equal size; the bytes found in
++|dvi_buf[0..half_buf-1]| constitute the first half, and those in
++|dvi_buf[half_buf..dvi_buf_size-1]| constitute the second. The global variable
++|dvi_ptr| points to the position that will receive the next output byte. When
++|dvi_ptr| reaches |dvi_limit|, which is always equal to one of the two values
++|half_buf| or |dvi_buf_size|, the half buffer that is about to be invaded next is
++sent to the output and |dvi_limit| is changed to its other value. Thus, there is
++always at least a half buffer's worth of information present, except at the very
++beginning of the job.
++
++Bytes of the \.{DVI} file are numbered sequentially starting with 0; the next
++byte to be generated will be number |dvi_offset+dvi_ptr|. A byte is present in
++the buffer only if its number is |>=dvi_gone|.
++
++Some systems may find it more efficient to make |dvi_buf| a |packed| array, since
++output of four bytes at once may be facilitated.
++
++Initially the buffer is all in one piece; we will output half of it only after it

++a complication because of the nested structure of |push| and |pop|
++commands. Suppose we add parentheses to the digit-subscripting problem,
++redefining hits so that $\delta_y\ldots \delta_y$ is a hit if all $y$'s between
++the $\delta$'s are enclosed in properly nested parentheses, and if the
++parenthesis level of the right-hand $\delta_y$ is deeper than or equal to
++that of the left-hand one. Thus, `(' and `)' correspond to `|push|'
++and `|pop|'. Now if we want to assign a subscript to the final 1 in the
++sequence
++$$2_y\,7_d\,1_d\,(\,8_z\,2_y\,8_z\,)\,1$$
++we cannot change the previous $1_d$ to $1_y$, since that would invalidate
++the $2_y\ldots2_y$ hit. But we can change it to $1_z$, scoring a hit
++since the intervening $8_z$'s are enclosed in parentheses.

++Versions of \TeX\ intended for small computers might well choose to omit the
++ideas in the next few parts of this program, since it is not really necessary to
++optimize the \.{DVI} code by making use of the |w0|, |x0|, |y0|, and |z0|
++commands. Furthermore, the algorithm that we are about to describe does not
++pretend to give an optimum reduction in the length of the \.{DVI} code; after
++all, speed is more important than compactness. But the method is surprisingly
++effective, and it takes comparatively little time.
++
++We can best understand the basic idea by first considering a simpler problem that
++has the same essential characteristics. Given a sequence of digits, say
++$3\,1\,4\,1\,5\,9\,2\,6\,5\,3\,5\,8\,9$, we want to assign subscripts $d$, $y$,
++or $z$ to each digit so as to maximize the number of ``$y$-hits'' and
++``$z$-hits''; a $y$-hit is an instance of two appearances of the same digit with
++the subscript $y$, where no $y$'s intervene between the two appearances, and a
++$z$-hit is defined similarly. For example, the sequence above could be decorated
++with subscripts as follows:
++$$3_z\,1_y\,4_d\,1_y\,5_y\,9_d\,2_d\,6_d\,5_y\,3_z\,5_y\,8_d\,9_d.$$ There are
++three $y$-hits ($1_y\ldots1_y$ and $5_y\ldots5_y\ldots5_y$) and one $z$-hit
++($3_z\ldots3_z$); there are no $d$-hits, since the two appearances of $9_d$ have
++$d$'s between them, but we don't count $d$-hits so it doesn't matter how many
++there are. These subscripts are analogous to the \.{DVI} commands called
++\\{down}, $y$, and $z$, and the digits are analogous to different amounts of
++vertical motion; a $y$-hit or $z$-hit corresponds to the opportunity to use the
++one-byte commands |y0| or |z0| in a \.{DVI} file.
++
++\TeX's method of assigning subscripts works like this: Append a new digit, say
++$\delta$, to the right of the sequence. Now look back through the sequence until
++one of the following things happens: (a)~You see $\delta_y$ or $\delta_z$, and
++this was the first time you encountered a $y$ or $z$ subscript, respectively.
++Then assign $y$ or $z$ to the new $\delta$; you have scored a hit. (b)~You see
++$\delta_d$, and no $y$ subscripts have been encountered so far during this
++search. Then change the previous $\delta_d$ to $\delta_y$ (this corresponds to
++changing a command in the output buffer), and assign $y$ to the new $\delta$;
++it's another hit. (c)~You see $\delta_d$, and a $y$ subscript has been seen but
++not a $z$. Change the previous $\delta_d$ to $\delta_z$ and assign $z$ to the new
++$\delta$. (d)~You encounter both $y$ and $z$ subscripts before encountering a
++suitable $\delta$, or you scan all the way to the front of the sequence. Assign
++$d$ to the new $\delta$; this assignment may be changed later.
++
++The subscripts $3_z\,1_y\,4_d\ldots\,$ in the example above were, in fact,
++produced by this procedure, as the reader can verify. (Go ahead and try it.)
++
++In order to implement such an idea, \TeX\ maintains a stack of pointers to the
++\\{down}, $y$, and $z$ commands that have been generated for the current page.
++And there is a similar stack for \\{right}, |w|, and |x| commands. These stacks
++are called the down stack and right stack, and their top elements are maintained
++in the variables |down_ptr| and |right_ptr|.
++
++Each entry in these stacks contains four fields: The |width| field is the amount
++of motion down or to the right; the |location| field is the byte number of the
++\.{DVI} command in question (including the appropriate |dvi_offset|); the |vlink|
++field points to the next item below this one on the stack; and the |vinfo| field
++encodes the options for possible change in the \.{DVI} command.

+-@ The most important output produced by a run of \TeX\ is the ``device
+-independent'' (\.{DVI}) file that specifies where characters and rules
+-are to appear on printed pages. The form of these files was designed by
+-David R. Fuchs in 1979. Almost any reasonable typesetting device can be
+-@^Fuchs, David Raymond@>
+-@:DVI_files}{\.{DVI} files@>
+-driven by a program that takes \.{DVI} files as input, and dozens of such
+-\.{DVI}-to-whatever programs have been written. Thus, it is possible to
+-print the output of \TeX\ on many different kinds of equipment, using \TeX\
+-as a device-independent ``front end.''
+-
+-A \.{DVI} file is a stream of 8-bit bytes, which may be regarded as a
+-series of commands in a machine-like language. The first byte of each command
+-is the operation code, and this code is followed by zero or more bytes
+-that provide parameters to the command. The parameters themselves may consist
+-of several consecutive bytes; for example, the `|set_rule|' command has two
+-parameters, each of which is four bytes long. Parameters are usually
+-regarded as nonnegative integers; but four-byte-long parameters,
+-and shorter parameters that denote distances, can be
+-either positive or negative. Such parameters are given in two's complement
+-notation. For example, a two-byte-long distance parameter has a value between
+-$-2^{15}$ and $2^{15}-1$. As in \.{TFM} files, numbers that occupy
+-more than one byte position appear in BigEndian order.
+-
+-A \.{DVI} file consists of a ``preamble,'' followed by a sequence of one
+-or more ``pages,'' followed by a ``postamble.'' The preamble is simply a
+-|pre| command, with its parameters that define the dimensions used in the
+-file; this must come first.  Each ``page'' consists of a |bop| command,
+-followed by any number of other commands that tell where characters are to
+-be placed on a physical page, followed by an |eop| command. The pages
+-appear in the order that \TeX\ generated them. If we ignore |nop| commands
+-and \\{fnt\_def} commands (which are allowed between any two commands in
+-the file), each |eop| command is immediately followed by a |bop| command,
+-or by a |post| command; in the latter case, there are no more pages in the
+-file, and the remaining bytes form the postamble.  Further details about
+-the postamble will be explained later.
+-
+-Some parameters in \.{DVI} commands are ``pointers.'' These are four-byte
+-quantities that give the location number of some other byte in the file;
+-the first byte is number~0, then comes number~1, and so on. For example,
+-one of the parameters of a |bop| command points to the previous |bop|;
+-this makes it feasible to read the pages in backwards order, in case the
+-results are being directed to a device that stacks its output face up.
+-Suppose the preamble of a \.{DVI} file occupies bytes 0 to 99. Now if the
+-first page occupies bytes 100 to 999, say, and if the second
+-page occupies bytes 1000 to 1999, then the |bop| that starts in byte 1000
+-points to 100 and the |bop| that starts in byte 2000 points to 1000. (The
+-very first |bop|, i.e., the one starting in byte 100, has a pointer of~$-1$.)
+-
+-@ The \.{DVI} format is intended to be both compact and easily interpreted
+-by a machine. Compactness is achieved by making most of the information
+-implicit instead of explicit. When a \.{DVI}-reading program reads the
+-commands for a page, it keeps track of several quantities: (a)~The current
+-font |f| is an integer; this value is changed only
+-by \\{fnt} and \\{fnt\_num} commands. (b)~The current position on the page
+-is given by two numbers called the horizontal and vertical coordinates,
+-|h| and |v|. Both coordinates are zero at the upper left corner of the page;
+-moving to the right corresponds to increasing the horizontal coordinate, and
+-moving down corresponds to increasing the vertical coordinate. Thus, the
+-coordinates are essentially Cartesian, except that vertical directions are
+-flipped; the Cartesian version of |(h,v)| would be |(h,-v)|.  (c)~The
+-current spacing amounts are given by four numbers |w|, |x|, |y|, and |z|,
+-where |w| and~|x| are used for horizontal spacing and where |y| and~|z|
+-are used for vertical spacing. (d)~There is a stack containing
+-|(h,v,w,x,y,z)| values; the \.{DVI} commands |push| and |pop| are used to
+-change the current level of operation. Note that the current font~|f| is
+-not pushed and popped; the stack contains only information about
+-positioning.
+-
+-The values of |h|, |v|, |w|, |x|, |y|, and |z| are signed integers having up
+-to 32 bits, including the sign. Since they represent physical distances,
+-there is a small unit of measurement such that increasing |h| by~1 means
+-moving a certain tiny distance to the right. The actual unit of
+-measurement is variable, as explained below; \TeX\ sets things up so that
+-its \.{DVI} output is in sp units, i.e., scaled points, in agreement with
+-all the |scaled| dimensions in \TeX's data structures.
+-
+-@ Here is a list of all the commands that may appear in a \.{DVI} file. Each
+-command is specified by its symbolic name (e.g., |bop|), its opcode byte
+-(e.g., 139), and its parameters (if any). The parameters are followed
+-by a bracketed number telling how many bytes they occupy; for example,
+-`|p[4]|' means that parameter |p| is four bytes long.
+-
+-\yskip\hang|set_char_0| 0. Typeset character number~0 from font~|f|
+-such that the reference point of the character is at |(h,v)|. Then
+-increase |h| by the width of that character. Note that a character may
+-have zero or negative width, so one cannot be sure that |h| will advance
+-after this command; but |h| usually does increase.
+-
+-\yskip\hang\\{set\_char\_1} through \\{set\_char\_127} (opcodes 1 to 127).
+-Do the operations of |set_char_0|; but use the character whose number
+-matches the opcode, instead of character~0.
+-
+-\yskip\hang|set1| 128 |c[1]|. Same as |set_char_0|, except that character
+-number~|c| is typeset. \TeX82 uses this command for characters in the
+-range |128<=c<256|.
+-
+-\yskip\hang|@!set2| 129 |c[2]|. Same as |set1|, except that |c|~is two
+-bytes long, so it is in the range |0<=c<65536|. \TeX82 never uses this
+-command, but it should come in handy for extensions of \TeX\ that deal
+-with oriental languages.
+-@^oriental characters@>@^Chinese characters@>@^Japanese characters@>
+-
+-\yskip\hang|@!set3| 130 |c[3]|. Same as |set1|, except that |c|~is three
+-bytes long, so it can be as large as $2^{24}-1$. Not even the Chinese
+-language has this many characters, but this command might prove useful
+-in some yet unforeseen extension.
+-
+-\yskip\hang|@!set4| 131 |c[4]|. Same as |set1|, except that |c|~is four
+-bytes long. Imagine that.
+-
+-\yskip\hang|set_rule| 132 |a[4]| |b[4]|. Typeset a solid black rectangle
+-of height~|a| and width~|b|, with its bottom left corner at |(h,v)|. Then
+-set |h:=h+b|. If either |a<=0| or |b<=0|, nothing should be typeset. Note
+-that if |b<0|, the value of |h| will decrease even though nothing else happens.
+-See below for details about how to typeset rules so that consistency with
+-\MF\ is guaranteed.
+-
+-\yskip\hang|@!put1| 133 |c[1]|. Typeset character number~|c| from font~|f|
+-such that the reference point of the character is at |(h,v)|. (The `put'
+-commands are exactly like the `set' commands, except that they simply put out a
+-character or a rule without moving the reference point afterwards.)
+-
+-\yskip\hang|@!put2| 134 |c[2]|. Same as |set2|, except that |h| is not changed.
+-
+-\yskip\hang|@!put3| 135 |c[3]|. Same as |set3|, except that |h| is not changed.
+-
+-\yskip\hang|@!put4| 136 |c[4]|. Same as |set4|, except that |h| is not changed.
+-
+-\yskip\hang|put_rule| 137 |a[4]| |b[4]|. Same as |set_rule|, except that
+-|h| is not changed.
+-
+-\yskip\hang|nop| 138. No operation, do nothing. Any number of |nop|'s
+-may occur between \.{DVI} commands, but a |nop| cannot be inserted between
+-a command and its parameters or between two parameters.
+-
+-\yskip\hang|bop| 139 $c_0[4]$ $c_1[4]$ $\ldots$ $c_9[4]$ $p[4]$. Beginning
+-of a page: Set |(h,v,w,x,y,z):=(0,0,0,0,0,0)| and set the stack empty. Set
+-the current font |f| to an undefined value.  The ten $c_i$ parameters hold
+-the values of \.{\\count0} $\ldots$ \.{\\count9} in \TeX\ at the time
+-\.{\\shipout} was invoked for this page; they can be used to identify
+-pages, if a user wants to print only part of a \.{DVI} file. The parameter
+-|p| points to the previous |bop| in the file; the first
+-|bop| has $p=-1$.
+-
+-\yskip\hang|eop| 140.  End of page: Print what you have read since the
+-previous |bop|. At this point the stack should be empty. (The \.{DVI}-reading
+-programs that drive most output devices will have kept a buffer of the
+-material that appears on the page that has just ended. This material is
+-largely, but not entirely, in order by |v| coordinate and (for fixed |v|) by
+-|h|~coordinate; so it usually needs to be sorted into some order that is
+-appropriate for the device in question.)
+-
+-\yskip\hang|push| 141. Push the current values of |(h,v,w,x,y,z)| onto the
+-top of the stack; do not change any of these values. Note that |f| is
+-not pushed.
+-
+-\yskip\hang|pop| 142. Pop the top six values off of the stack and assign
+-them respectively to |(h,v,w,x,y,z)|. The number of pops should never
+-exceed the number of pushes, since it would be highly embarrassing if the
+-stack were empty at the time of a |pop| command.
+-
+-\yskip\hang|right1| 143 |b[1]|. Set |h:=h+b|, i.e., move right |b| units.
+-The parameter is a signed number in two's complement notation, |-128<=b<128|;
+-if |b<0|, the reference point moves left.
+-
+-\yskip\hang|right2| 144 |b[2]|. Same as |right1|, except that |b| is a
+-two-byte quantity in the range |-32768<=b<32768|.
+-
+-\yskip\hang|right3| 145 |b[3]|. Same as |right1|, except that |b| is a
+-three-byte quantity in the range |@t$-2^{23}$@><=b<@t$2^{23}$@>|.
+-
+-\yskip\hang|right4| 146 |b[4]|. Same as |right1|, except that |b| is a
+-four-byte quantity in the range |@t$-2^{31}$@><=b<@t$2^{31}$@>|.
+-
+-\yskip\hang|w0| 147. Set |h:=h+w|; i.e., move right |w| units. With luck,
+-this parameterless command will usually suffice, because the same kind of motion
+-will occur several times in succession; the following commands explain how
+-|w| gets particular values.
+-
+-\yskip\hang|w1| 148 |b[1]|. Set |w:=b| and |h:=h+b|. The value of |b| is a
+-signed quantity in two's complement notation, |-128<=b<128|. This command
+-changes the current |w|~spacing and moves right by |b|.
+-
+-\yskip\hang|@!w2| 149 |b[2]|. Same as |w1|, but |b| is two bytes long,
+-|-32768<=b<32768|.
+-
+-\yskip\hang|@!w3| 150 |b[3]|. Same as |w1|, but |b| is three bytes long,

+-
+-\yskip\hang|@!w4| 151 |b[4]|. Same as |w1|, but |b| is four bytes long,
+-|@t$-2^{31}$@><=b<@t$2^{31}$@>|.
+-
+-\yskip\hang|x0| 152. Set |h:=h+x|; i.e., move right |x| units. The `|x|'
+-commands are like the `|w|' commands except that they involve |x| instead
+-of |w|.
+-
+-\yskip\hang|x1| 153 |b[1]|. Set |x:=b| and |h:=h+b|. The value of |b| is a
+-signed quantity in two's complement notation, |-128<=b<128|. This command
+-changes the current |x|~spacing and moves right by |b|.
+-
+-\yskip\hang|@!x2| 154 |b[2]|. Same as |x1|, but |b| is two bytes long,
+-|-32768<=b<32768|.

+-\yskip\hang|@!x4| 156 |b[4]|. Same as |x1|, but |b| is four bytes long,
+-|@t$-2^{31}$@><=b<@t$2^{31}$@>|.
+-
+-\yskip\hang|down1| 157 |a[1]|. Set |v:=v+a|, i.e., move down |a| units.
+-The parameter is a signed number in two's complement notation, |-128<=a<128|;
+-if |a<0|, the reference point moves up.
+-
+-\yskip\hang|@!down2| 158 |a[2]|. Same as |down1|, except that |a| is a
+-two-byte quantity in the range |-32768<=a<32768|.
+-
+-\yskip\hang|@!down3| 159 |a[3]|. Same as |down1|, except that |a| is a
+-three-byte quantity in the range |@t$-2^{23}$@><=a<@t$2^{23}$@>|.
+-

+-four-byte quantity in the range |@t$-2^{31}$@><=a<@t$2^{31}$@>|.
+-
+-\yskip\hang|y0| 161. Set |v:=v+y|; i.e., move down |y| units. With luck,
+-this parameterless command will usually suffice, because the same kind of motion
+-will occur several times in succession; the following commands explain how
+-|y| gets particular values.
+-
+-\yskip\hang|y1| 162 |a[1]|. Set |y:=a| and |v:=v+a|. The value of |a| is a
+-signed quantity in two's complement notation, |-128<=a<128|. This command
+-changes the current |y|~spacing and moves down by |a|.
+-
+-\yskip\hang|@!y2| 163 |a[2]|. Same as |y1|, but |a| is two bytes long,
+-|-32768<=a<32768|.
+-
+-\yskip\hang|@!y3| 164 |a[3]|. Same as |y1|, but |a| is three bytes long,
+-|@t$-2^{23}$@><=a<@t$2^{23}$@>|.
+-
+-\yskip\hang|@!y4| 165 |a[4]|. Same as |y1|, but |a| is four bytes long,
+-|@t$-2^{31}$@><=a<@t$2^{31}$@>|.
+-
+-\yskip\hang|z0| 166. Set |v:=v+z|; i.e., move down |z| units. The `|z|' commands
+-are like the `|y|' commands except that they involve |z| instead of |y|.
+-
+-\yskip\hang|z1| 167 |a[1]|. Set |z:=a| and |v:=v+a|. The value of |a| is a
+-signed quantity in two's complement notation, |-128<=a<128|. This command
+-changes the current |z|~spacing and moves down by |a|.
+-
+-\yskip\hang|@!z2| 168 |a[2]|. Same as |z1|, but |a| is two bytes long,
+-|-32768<=a<32768|.
+-
+-\yskip\hang|@!z3| 169 |a[3]|. Same as |z1|, but |a| is three bytes long,
+-|@t$-2^{23}$@><=a<@t$2^{23}$@>|.
+-
+-\yskip\hang|@!z4| 170 |a[4]|. Same as |z1|, but |a| is four bytes long,
+-|@t$-2^{31}$@><=a<@t$2^{31}$@>|.
+-
+-\yskip\hang|fnt_num_0| 171. Set |f:=0|. Font 0 must previously have been
+-defined by a \\{fnt\_def} instruction, as explained below.
+-
+-\yskip\hang\\{fnt\_num\_1} through \\{fnt\_num\_63} (opcodes 172 to 234). Set
+-|f:=1|, \dots, \hbox{|f:=63|}, respectively.
+-
+-\yskip\hang|fnt1| 235 |k[1]|. Set |f:=k|. \TeX82 uses this command for font
+-numbers in the range |64<=k<256|.
+-
+-\yskip\hang|@!fnt2| 236 |k[2]|. Same as |fnt1|, except that |k|~is two
+-bytes long, so it is in the range |0<=k<65536|. \TeX82 never generates this
+-command, but large font numbers may prove useful for specifications of
+-color or texture, or they may be used for special fonts that have fixed
+-numbers in some external coding scheme.
+-
+-\yskip\hang|@!fnt3| 237 |k[3]|. Same as |fnt1|, except that |k|~is three
+-bytes long, so it can be as large as $2^{24}-1$.
+-
+-\yskip\hang|@!fnt4| 238 |k[4]|. Same as |fnt1|, except that |k|~is four
+-bytes long; this is for the really big font numbers (and for the negative ones).
+-
+-\yskip\hang|xxx1| 239 |k[1]| |x[k]|. This command is undefined in
+-general; it functions as a $(k+2)$-byte |nop| unless special \.{DVI}-reading
+-programs are being used. \TeX82 generates |xxx1| when a short enough
+-\.{\\special} appears, setting |k| to the number of bytes being sent. It
+-is recommended that |x| be a string having the form of a keyword followed
+-by possible parameters relevant to that keyword.
+-
+-\yskip\hang|@!xxx2| 240 |k[2]| |x[k]|. Like |xxx1|, but |0<=k<65536|.
+-
+-\yskip\hang|@!xxx3| 241 |k[3]| |x[k]|. Like |xxx1|, but |0<=k<@t$2^{24}$@>|.
+-

+-
+-@ The preamble contains basic information about the file as a whole. As
+-stated above, there are six parameters:
+-$$\hbox{|@!i[1]| |@!num[4]| |@!den[4]| |@!mag[4]| |@!k[1]| |@!x[k]|.}$$
+-The |i| byte identifies \.{DVI} format; currently this byte is always set
+-to~2. (The value |i=3| is currently used for an extended format that
+-allows a mixture of right-to-left and left-to-right typesetting.
+-Some day we will set |i=4|, when \.{DVI} format makes another
+-incompatible change---perhaps in the year 2048.)
+-
+-The next two parameters, |num| and |den|, are positive integers that define
+-the units of measurement; they are the numerator and denominator of a
+-fraction by which all dimensions in the \.{DVI} file could be multiplied
+-in order to get lengths in units of $10^{-7}$ meters. Since $\rm 7227{pt} =
+-254{cm}$, and since \TeX\ works with scaled points where there are $2^{16}$
+-sp in a point, \TeX\ sets
+-$|num|/|den|=(254\cdot10^5)/(7227\cdot2^{16})=25400000/473628672$.
+-@^sp@>
+-
+-The |mag| parameter is what \TeX\ calls \.{\\mag}, i.e., 1000 times the
+-desired magnification. The actual fraction by which dimensions are
+-multiplied is therefore $|mag|\cdot|num|/1000|den|$. Note that if a \TeX\
+-source document does not call for any `\.{true}' dimensions, and if you
+-change it only by specifying a different \.{\\mag} setting, the \.{DVI}
+-file that \TeX\ creates will be completely unchanged except for the value
+-of |mag| in the preamble and postamble. (Fancy \.{DVI}-reading programs allow
+-users to override the |mag|~setting when a \.{DVI} file is being printed.)
+-
+-Finally, |k| and |x| allow the \.{DVI} writer to include a comment, which is not
+-interpreted further. The length of comment |x| is |k|, where |0<=k<256|.
+-
+-
+-@c
+-#define id_byte 2               /* identifies the kind of \.{DVI} files described here */
+-
+-@ Font definitions for a given font number |k| contain further parameters
+-$$\hbox{|c[4]| |s[4]| |d[4]| |a[1]| |l[1]| |n[a+l]|.}$$
+-The four-byte value |c| is the check sum that \TeX\ found in the \.{TFM}
+-file for this font; |c| should match the check sum of the font found by
+-programs that read this \.{DVI} file.
+-@^check sum@>
+-
+-Parameter |s| contains a fixed-point scale factor that is applied to
+-the character widths in font |k|; font dimensions in \.{TFM} files and
+-other font files are relative to this quantity, which is called the
+-``at size'' elsewhere in this documentation. The value of |s| is
+-always positive and less than $2^{27}$. It is given in the same units
+-as the other \.{DVI} dimensions, i.e., in sp when \TeX82 has made the
+-file.  Parameter |d| is similar to |s|; it is the ``design size,'' and
+-(like~|s|) it is given in \.{DVI} units. Thus, font |k| is to be used
+-at $|mag|\cdot s/1000d$ times its normal size.
+-
+-The remaining part of a font definition gives the external name of the font,
+-which is an ASCII string of length |a+l|. The number |a| is the length
+-of the ``area'' or directory, and |l| is the length of the font name itself;
+-the standard local system font area is supposed to be used when |a=0|.
+-The |n| field contains the area in its first |a| bytes.
+-
+-Font definitions must appear before the first use of a particular font number.
+-Once font |k| is defined, it must not be defined again; however, we
+-shall see below that font definitions appear in the postamble as well as
+-in the pages, so in this sense each font number is defined exactly twice,
+-if at all. Like |nop| commands, font definitions can
+-appear before the first |bop|, or between an |eop| and a |bop|.
+-
+-@ Sometimes it is desirable to make horizontal or vertical rules line up
+-precisely with certain features in characters of a font. It is possible to
+-guarantee the correct matching between \.{DVI} output and the characters
+-generated by \MF\ by adhering to the following principles: (1)~The \MF\
+-characters should be positioned so that a bottom edge or left edge that is
+-supposed to line up with the bottom or left edge of a rule appears at the
+-reference point, i.e., in row~0 and column~0 of the \MF\ raster. This
+-ensures that the position of the rule will not be rounded differently when
+-the pixel size is not a perfect multiple of the units of measurement in
+-the \.{DVI} file. (2)~A typeset rule of height $a>0$ and width $b>0$
+-should be equivalent to a \MF-generated character having black pixels in
+-precisely those raster positions whose \MF\ coordinates satisfy
+-|0<=x<@t$\alpha$@>b| and |0<=y<@t$\alpha$@>a|, where $\alpha$ is the number
+-of pixels per \.{DVI} unit.

+-@^rules aligning with characters@>
+-
+-@ The last page in a \.{DVI} file is followed by `|post|'; this command
+-introduces the postamble, which summarizes important facts that \TeX\ has
+-accumulated about the file, making it possible to print subsets of the data
+-with reasonable efficiency. The postamble has the form
+-$$\vbox{\halign{\hbox{#\hfil}\cr
+-  |post| |p[4]| |num[4]| |den[4]| |mag[4]| |l[4]| |u[4]| |s[2]| |t[2]|\cr
+-  $\langle\,$font definitions$\,\rangle$\cr
+-  |post_post| |q[4]| |i[1]| 223's$[{\G}4]$\cr}}$$
+-Here |p| is a pointer to the final |bop| in the file. The next three
+-parameters, |num|, |den|, and |mag|, are duplicates of the quantities that
+-appeared in the preamble.
+-
+-Parameters |l| and |u| give respectively the height-plus-depth of the tallest
+-page and the width of the widest page, in the same units as other dimensions
+-of the file. These numbers might be used by a \.{DVI}-reading program to
+-position individual ``pages'' on large sheets of film or paper; however,
+-the standard convention for output on normal size paper is to position each
+-page so that the upper left-hand corner is exactly one inch from the left
+-and the top. Experience has shown that it is unwise to design \.{DVI}-to-printer
+-software that attempts cleverly to center the output; a fixed position of
+-the upper left corner is easiest for users to understand and to work with.
+-Therefore |l| and~|u| are often ignored.
+-
+-Parameter |s| is the maximum stack depth (i.e., the largest excess of
+-|push| commands over |pop| commands) needed to process this file. Then
+-comes |t|, the total number of pages (|bop| commands) present.
+-
+-The postamble continues with font definitions, which are any number of
+-\\{fnt\_def} commands as described above, possibly interspersed with |nop|
+-commands. Each font number that is used in the \.{DVI} file must be defined
+-exactly twice: Once before it is first selected by a \\{fnt} command, and once
+-in the postamble.
+-
+-@ The last part of the postamble, following the |post_post| byte that
+-signifies the end of the font definitions, contains |q|, a pointer to the
+-|post| command that started the postamble.  An identification byte, |i|,
+-comes next; this currently equals~2, as in the preamble.
+-
+-The |i| byte is followed by four or more bytes that are all equal to
+-the decimal number 223 (i.e., '337 in octal). \TeX\ puts out four to seven of
+-these trailing bytes, until the total length of the file is a multiple of
+-four bytes, since this works out best on machines that pack four bytes per
+-word; but any number of 223's is allowed, as long as there are at least four
+-of them. In effect, 223 is a sort of signature that is added at the very end.
+-@^Fuchs, David Raymond@>
+-
+-This curious way to finish off a \.{DVI} file makes it feasible for
+-\.{DVI}-reading programs to find the postamble first, on most computers,
+-even though \TeX\ wants to write the postamble last. Most operating
+-systems permit random access to individual words or bytes of a file, so
+-the \.{DVI} reader can start at the end and skip backwards over the 223's
+-until finding the identification byte. Then it can back up four bytes, read
+-|q|, and move to byte |q| of the file. This byte should, of course,
+-contain the value 248 (|post|); now the postamble can be read, so the
+-\.{DVI} reader can discover all the information needed for typesetting the
+-pages. Note that it is also possible to skip through the \.{DVI} file at
+-reasonably high speed to locate a particular page, if that proves
+-desirable. This saves a lot of time, since \.{DVI} files used in production
+-jobs tend to be large.
+-
+-Unfortunately, however, standard \PASCAL\ does not include the ability to
+-@^system dependencies@>
+-access a random position in a file, or even to determine the length of a file.
+-Almost all systems nowadays provide the necessary capabilities, so \.{DVI}
+-format has been designed to work most efficiently with modern operating systems.
+-But if \.{DVI} files have to be processed under the restrictions of standard
+-\PASCAL, one can simply read them from front to back, since the necessary
+-header information is present in the preamble and in the font definitions.
+-(The |l| and |u| and |s| and |t| parameters, which appear only in the
+-postamble, are ``frills'' that are handy but not absolutely necessary.)

+-
+-@* \[32] Shipping pages out.
+-After considering \TeX's eyes and stomach, we come now to the bowels.
+-@^bowels@>
+-
+-The |ship_out| procedure is given a pointer to a box; its mission is
+-to describe that box in \.{DVI} form, outputting a ``page'' to |dvi_file|.
+-The \.{DVI} coordinates $(h,v)=(0,0)$ should correspond to the upper left
+-corner of the box being shipped.
+-
+-Since boxes can be inside of boxes inside of boxes, the main work of
+-|ship_out| is done by two mutually recursive routines, |hlist_out|
+-and |vlist_out|, which traverse the hlists and vlists inside of horizontal
+-and vertical boxes.
+-
+-As individual pages are being processed, we need to accumulate
+-information about the entire set of pages, since such statistics must be
+-reported in the postamble. The global variables |total_pages|, |max_v|,
+-|max_h|, |max_push|, and |last_bop| are used to record this information.
+-
+-The variable |doing_leaders| is |true| while leaders are being output.
+-The variable |dead_cycles| contains the number of times an output routine
+-has been initiated since the last |ship_out|.
+-
+-A few additional global variables are also defined here for use in
+-|vlist_out| and |hlist_out|. They could have been local variables, but
+-that would waste stack space when boxes are deeply nested, since the
+-values of these variables are not needed during recursive calls.

+-
+-@ The \.{DVI} bytes are output to a buffer instead of being written directly
+-to the output file. This makes it possible to reduce the overhead of
+-subroutine calls, thereby measurably speeding up the computation, since
+-output of \.{DVI} bytes is part of \TeX's inner loop. And it has another
+-advantage as well, since we can change instructions in the buffer in order to
+-make the output more compact. For example, a `|down2|' command can be
+-changed to a `|y2|', thereby making a subsequent `|y0|' command possible,
+-saving two bytes.
+-
+-The output buffer is divided into two parts of equal size; the bytes found
+-in |dvi_buf[0..half_buf-1]| constitute the first half, and those in
+-|dvi_buf[half_buf..dvi_buf_size-1]| constitute the second. The global
+-variable |dvi_ptr| points to the position that will receive the next
+-output byte. When |dvi_ptr| reaches |dvi_limit|, which is always equal
+-to one of the two values |half_buf| or |dvi_buf_size|, the half buffer that
+-is about to be invaded next is sent to the output and |dvi_limit| is
+-changed to its other value. Thus, there is always at least a half buffer's
+-worth of information present, except at the very beginning of the job.
+-
+-Bytes of the \.{DVI} file are numbered sequentially starting with 0;
+-the next byte to be generated will be number |dvi_offset+dvi_ptr|.
+-A byte is present in the buffer only if its number is |>=dvi_gone|.
+-
+-Some systems may find it more efficient to make |dvi_buf| a |packed|
+-array, since output of four bytes at once may be facilitated.

+-int dvi_gone = 0;               /* the number of bytes already output to |dvi_file| */
+-
+-@ The actual output of |dvi_buf[a..b]| to |dvi_file| is performed by calling
+-|write_dvi(a,b)|. For best results, this procedure should be optimized to

+-
+-@ Versions of \TeX\ intended for small computers might well choose to omit
+-the ideas in the next few parts of this program, since it is not really
+-necessary to optimize the \.{DVI} code by making use of the |w0|, |x0|,
+-|y0|, and |z0| commands. Furthermore, the algorithm that we are about to
+-describe does not pretend to give an optimum reduction in the length
+-of the \.{DVI} code; after all, speed is more important than compactness.
+-But the method is surprisingly effective, and it takes comparatively little
+-time.
+-
+-We can best understand the basic idea by first considering a simpler problem
+-that has the same essential characteristics. Given a sequence of digits,
+-say $3\,1\,4\,1\,5\,9\,2\,6\,5\,3\,5\,8\,9$, we want to assign subscripts
+-$d$, $y$, or $z$ to each digit so as to maximize the number of ``$y$-hits''
+-and ``$z$-hits''; a $y$-hit is an instance of two appearances of the same
+-digit with the subscript $y$, where no $y$'s intervene between the two
+-appearances, and a $z$-hit is defined similarly. For example, the sequence
+-above could be decorated with subscripts as follows:
+-$$3_z\,1_y\,4_d\,1_y\,5_y\,9_d\,2_d\,6_d\,5_y\,3_z\,5_y\,8_d\,9_d.$$
+-There are three $y$-hits ($1_y\ldots1_y$ and $5_y\ldots5_y\ldots5_y$) and
+-one $z$-hit ($3_z\ldots3_z$); there are no $d$-hits, since the two appearances
+-of $9_d$ have $d$'s between them, but we don't count $d$-hits so it doesn't
+-matter how many there are. These subscripts are analogous to the \.{DVI}
+-commands called \\{down}, $y$, and $z$, and the digits are analogous to
+-different amounts of vertical motion; a $y$-hit or $z$-hit corresponds to
+-the opportunity to use the one-byte commands |y0| or |z0| in a \.{DVI} file.
+-
+-\TeX's method of assigning subscripts works like this: Append a new digit,
+-say $\delta$, to the right of the sequence. Now look back through the
+-sequence until one of the following things happens: (a)~You see
+-$\delta_y$ or $\delta_z$, and this was the first time you encountered a
+-$y$ or $z$ subscript, respectively.  Then assign $y$ or $z$ to the new
+-$\delta$; you have scored a hit. (b)~You see $\delta_d$, and no $y$
+-subscripts have been encountered so far during this search.  Then change
+-the previous $\delta_d$ to $\delta_y$ (this corresponds to changing a
+-command in the output buffer), and assign $y$ to the new $\delta$; it's
+-another hit.  (c)~You see $\delta_d$, and a $y$ subscript has been seen
+-but not a $z$.  Change the previous $\delta_d$ to $\delta_z$ and assign
+-$z$ to the new $\delta$. (d)~You encounter both $y$ and $z$ subscripts
+-before encountering a suitable $\delta$, or you scan all the way to the
+-front of the sequence. Assign $d$ to the new $\delta$; this assignment may
+-be changed later.
+-
+-The subscripts $3_z\,1_y\,4_d\ldots\,$ in the example above were, in fact,
+-produced by this procedure, as the reader can verify. (Go ahead and try it.)
+-
+-@ In order to implement such an idea, \TeX\ maintains a stack of pointers
+-to the \\{down}, $y$, and $z$ commands that have been generated for the
+-current page. And there is a similar stack for \\{right}, |w|, and |x|
+-commands. These stacks are called the down stack and right stack, and their
+-top elements are maintained in the variables |down_ptr| and |right_ptr|.
+-
+-Each entry in these stacks contains four fields: The |width| field is
+-the amount of motion down or to the right; the |location| field is the
+-byte number of the \.{DVI} command in question (including the appropriate
+-|dvi_offset|); the |vlink| field points to the next item below this one
+-on the stack; and the |vinfo| field encodes the options for possible change
+-in the \.{DVI} command.

+-This implementation of readchar() uses parts of the program dvips
+-written by Tomas Rokicki--the inventor of the pkformat--(loadfont.c,
+-download.c and unpack.c). Dvips in turn is derived from pktype.
+-Pktype(TeX) is described in debt in ``The PKtype processor'',
+-which is available as pktype.weave as part of the METAFONTware.
+-What was needed to implement readchar() is rearranged in pkfile.c to
+-get more modularity in the style of MODULA2.

++
++    The information in a \TFM\file appears in a sequence of 8-bit bytes. Since
++    the number of bytes is always a multiple of 4, we could also regard the file
++    as a sequence of 32-bit words, but \TeX\ uses the byte interpretation. The
++    format of \TFM\files was designed by Lyle Ramshaw in 1980. The intent is
++    to convey a lot of different kinds of information in a compact but useful
++    form.
++
++    $\Omega$ is capable of reading not only \TFM\files, but also \.{OFM}
++    files, which can describe fonts with up to 65536 characters and with huge
++    lig/kern tables. These fonts will often be virtual fonts built up from real
++    fonts with 256 characters, but $\Omega$ is not aware of this.
++
++    The documentation below describes \TFM\files, with slight additions to
++    show where \.{OFM} files differ.
++
++    The first 24 bytes (6 words) of a \TFM\file contain twelve 16-bit integers
++    that give the lengths of the various subsequent portions of the file. These
++    twelve integers are, in order:
++
++    \starttabulate
++        \NC \type {lf| \NC length of the entire file, in words \NC \NR
++        \NC \type {lh| \NC length of the header data, in words \NC \NR
++        \NC \type {bc| \NC smallest character code in the font \NC \NR
++        \NC \type {ec| \NC largest character code in the font \NC \NR
++        \NC \type {nw| \NC number of words in the width table \NC \NR
++        \NC \type {nh| \NC number of words in the height table \NC \NR
++        \NC \type {nd| \NC number of words in the depth table \NC \NR
++        \NC \type {ni| \NC number of words in the italic correction table \NC \NR
++        \NC \type {nl| \NC number of words in the lig/kern table \NC \NR
++        \NC \type {nk| \NC number of words in the kern table \NC \NR
++        \NC \type {ne| \NC number of words in the extensible character table \NC \NR
++        \NC \type {np| \NC number of font parameter words \NC \NR
++    \stoptabulate
++
++    They are all nonnegative and less than $2^{15}$. We must have
++    |bc-1<=ec<=255|, and $|lf=6+lh+(ec-bc+1)+nw+nh+nd+ni+nl+nk+ne+np|$. Note that
++    a \TFM\font may contain as many as 256 characters (if |bc=0| and
++    |ec=255|), and as few as 0 characters (if |bc=ec+1|).
++
++    Incidentally, when two or more 8-bit bytes are combined to form an integer of
++    16 or more bits, the most significant bytes appear first in the file. This is
++    called BigEndian order.
++
++    The first 52 bytes (13 words) of an \.{OFM} file contains thirteen 32-bit
++    integers that give the lengths of the various subsequent portions of the
++    file. The first word is 0 (future versions of \.{OFM} files could have
++    different values; what is important is that the first two bytes be 0 to
++    differentiate \TFM\and \.{OFM} files). The next twelve integers are as
++    above, all nonegative and less than~$2^{31}$. We must have |bc-1<=ec<=65535|,
++    and $$\hbox{|lf=13+lh+2*(ec-bc+1)+nw+nh+nd+ni+nl+nk+ne+np|.}$$ Note that an
++    \.{OFM} font may contain as many as 65536 characters (if |bc=0| and
++    |ec=65535|), and as few as 0 characters (if |bc=ec+1|).
++
++    The rest of the \TFM\file may be regarded as a sequence of ten data arrays
++    having the informal specification
++
++    \starttabulate
++    \NC \type {header}     \NC \type {[0..lh-1]} \NC \type {stuff} \NC \NR
++    \NC \type {char\_info} \NC \type {[bc..ec]}  \NC \type {char_info_word} \NC \NR
++    \NC \type {width}      \NC \type {[0..nw-1]} \NC \type {fix_word} \NC \NR
++    \NC \type {height}     \NC \type {[0..nh-1]} \NC \type {fix_word} \NC \NR
++    \NC \type {depth}      \NC \type {[0..nd-1]} \NC \type {fix_word} \NC \NR
++    \NC \type {italic}     \NC \type {[0..ni-1]} \NC \type {fix_word} \NC \NR
++    \NC \type {lig\_kern}  \NC \type {[0..nl-1]} \NC \type {lig_kern_command} \NC \NR
++    \NC \type {kern}       \NC \type {[0..nk-1]} \NC \type {fix_word} \NC \NR
++    \NC \type {exten}      \NC \type {[0..ne-1]} \NC \type {extensible_recipe} \NC \NR
++    \NC \type {param}      \NC \type {[1..np]}   \NC \type {fix_word} \NC \NR
++    \stoptabulate
++
++    The most important data type used here is a |@!fix_word|, which is a 32-bit
++    representation of a binary fraction. A |fix_word| is a signed quantity, with
++    the two's complement of the entire word used to represent negation. Of the 32
++    bits in a |fix_word|, exactly 12 are to the left of the binary point; thus,
++    the largest |fix_word| value is $2048-2^{-20}$, and the smallest is $-2048$.
++    We will see below, however, that all but two of the |fix_word| values must
++    lie between $-16$ and $+16$.
++
++    The first data array is a block of header information, which contains general
++    facts about the font. The header must contain at least two words, |header[0]|
++    and |header[1]|, whose meaning is explained below. Additional header
++    information of use to other software routines might also be included, but
++    \TeX82 does not need to know about such details. For example, 16 more words
++    of header information are in use at the Xerox Palo Alto Research Center; the
++    first ten specify the character coding scheme used (e.g., `\.{XEROX text}' or
++    `\.{TeX math symbols}'), the next five give the font identifier (e.g.,
++    `\.{HELVETICA}' or `\.{CMSY}'), and the last gives the ``face byte.'' The
++    program that converts \.{DVI} files to Xerox printing format gets this
++    information by looking at the \TFM\file, which it needs to read anyway
++    because of other information that is not explicitly repeated in
++    \.{DVI}~format.
++
++    \startitemize
++
++        \startitem
++            |header[0]| is a 32-bit check sum that \TeX\ will copy into the
++            \.{DVI} output file. Later on when the \.{DVI} file is printed,
++            possibly on another computer, the actual font that gets used is
++            supposed to have a check sum that agrees with the one in the \TFM\
++            file used by \TeX. In this way, users will be warned about potential
++            incompatibilities. (However, if the check sum is zero in either the
++            font file or the \TFM\file, no check is made.) The actual relation
++            between this check sum and the rest of the \TFM\file is not
++            important; the check sum is simply an identification number with the
++            property that incompatible fonts almost always have distinct check
++            sums.
++        \stopitem
++
++        \startitem
++            |header[1]| is a |fix_word| containing the design size of the font,
++            in units of \TeX\ points. This number must be at least 1.0; it is
++            fairly arbitrary, but usually the design size is 10.0 for a ``10
++            point'' font, i.e., a font that was designed to look best at a
++            10-point size, whatever that really means. When a \TeX\ user asks for
++            a font `\.{at} $\delta$ \.{pt}', the effect is to override the design
++            size and replace it by $\delta$, and to multiply the $x$ and~$y$
++            coordinates of the points in the font image by a factor of $\delta$
++            divided by the design size. {\sl All other dimensions in the\/
++            \TFM\file are |fix_word|\kern-1pt\ numbers in design-size units},
++            with the exception of |param[1]| (which denotes the slant ratio).
++            Thus, for example, the value of |param[6]|, which defines the \.{em}
++            unit, is often the |fix_word| value $2^{20}=1.0$, since many fonts
++            have a design size equal to one em. The other dimensions must be less
++            than 16 design-size units in absolute value; thus, |header[1]| and
++            |param[1]| are the only |fix_word| entries in the whole \TFM\file
++            whose first byte might be something besides 0 or 255.
++        \stopitem
++
++    \stopitemize
++
++    Next comes the |char_info| array, which contains one |@!char_info_word| per
++    character. Each word in this part of a \TFM\file contains six fields
++    packed into four bytes as follows.
++
++    \startitemize
++        \startitem
++            first byte: |width_index| (8 bits)
++        \stopitem
++        \startitem
++            second byte: |height_index| (4 bits) times 16, plus |depth_index|
++            (4~bits)
++        \stopitem
++        \startitem
++            third byte: |italic_index| (6 bits) times 4, plus |tag| (2~bits)
++        \stopitem
++        \startitem
++            fourth byte: |remainder| (8 bits)
++        \stopitem
++    \stopitemize
++
++    The actual width of a character is \\{width}|[width_index]|, in design-size
++    units; this is a device for compressing information, since many characters
++    have the same width. Since it is quite common for many characters to have the
++    same height, depth, or italic correction, the \TFM\format imposes a limit
++    of 16 different heights, 16 different depths, and 64 different italic
++    corrections.
++
++    For \.{OFM} files, two words (eight bytes) are used. The arrangement is as
++    follows.
++
++    \startitemize
++        \startitem
++            first and second bytes: |width_index| (16 bits)
++        \stopitem
++            \startitem third byte: |height_index| (8 bits)
++        \stopitem
++        \startitem
++            fourth byte: |depth_index| (8~bits)
++        \stopitem
++        \startitem
++            fifth and sixth bytes: |italic_index| (14 bits) times 4, plus |tag|
++            (2~bits)
++        \startitem
++            seventh and eighth bytes: |remainder| (16 bits)
++        \stopitem
++    \stopitemize
++
++    Therefore the \.{OFM} format imposes a limit of 256 different heights, 256
++    different depths, and 16384 different italic corrections.
++
++    The italic correction of a character has two different uses. (a)~In ordinary
++    text, the italic correction is added to the width only if the \TeX\ user
++    specifies `\.{\\/}' after the character. (b)~In math formulas, the italic
++    correction is always added to the width, except with respect to the
++    positioning of subscripts.
++
++    Incidentally, the relation $\\{width}[0]=\\{height}[0]=\\{depth}[0]=
++    \\{italic}[0]=0$ should always hold, so that an index of zero implies a value
++    of zero. The |width_index| should never be zero unless the character does not
++    exist in the font, since a character is valid if and only if it lies between
++    |bc| and |ec| and has a nonzero |width_index|.
++
++    \TeX\ checks the information of a \TFM\file for validity as the file is
++    being read in, so that no further checks will be needed when typesetting is
++    going on. The somewhat tedious subroutine that does this is called
++    |read_font_info|. It has four parameters: the user font identifier~|u|, the
++    file name and area strings |nom| and |aire|, and the ``at'' size~|s|. If
++    |s|~is negative, it's the negative of a scale factor to be applied to the
++    design size; |s=-1000| is the normal case. Otherwise |s| will be substituted
++    for the design size; in this case, |s| must be positive and less than
++    $2048\rm\,pt$ (i.e., it must be less than $2^{27}$ when considered as an
++    integer).
++
++    The subroutine opens and closes a global file variable called |tfm_file|. It
++    returns the value of the internal font number that was just loaded. If an
++    error is detected, an error message is issued and no font information is
++    stored; |null_font| is returned in this case.
++
++    The |tag| field in a |char_info_word| has four values that explain how to
++    interpret the |remainder| field.
++
++    \startitemize
++        \startitem
++            |tag=0| (|no_tag|) means that |remainder| is unused.
++        \stopitem
++        \startitem
++            |tag=1| (|lig_tag|) means that this character has a ligature/kerning
++            program starting at position |remainder| in the |lig_kern| array
++        \stopitem
++        \startitem
++            |tag=2| (|list_tag|) means that this character is part of a chain of
++            characters of ascending sizes, and not the largest in the chain. The
++            |remainder| field gives the character code of the next larger
++            character
++        \stopitem
++        \startitem
++            |tag=3| (|ext_tag|) means that this character code represents an
++            extensible character, i.e., a character that is built up of smaller
++            pieces so that it can be made arbitrarily large. The pieces are
++            specified in |exten[remainder]|
++        \stopitem
++    \stopitemize
++
++    Characters with |tag=2| and |tag=3| are treated as characters with |tag=0|
++    unless they are used in special circumstances in math formulas. For example,
++    the \.{\\sum} operation looks for a |list_tag|, and the \.{\\left} operation
++    looks for both |list_tag| and |ext_tag|.
++
++    The |lig_kern| array contains instructions in a simple programming language
++    that explains what to do for special letter pairs. Each word in this array,
++    in a \TFM\file, is a |@!lig_kern_command| of four bytes.
++
++    \startitemize
++        \startitem
++            first byte: |skip_byte|, indicates that this is the final program
++            step if the byte is 128 or more, otherwise the next step is obtained
++            by skipping this number of intervening steps
++        \stopitem
++        \startitem
++            second byte: |next_char|, if |next_char| follows the current
++            character, then perform the operation and stop, otherwise
++            continue
++        \stopitem
++        \startitem
++            third byte: |op_byte|, indicates a ligature step if less than~128, a
++            kern step otherwise
++        \stopitem
++        \startitem
++            fourth byte: |remainder|
++        \stopitem
++    \stopitemize
++
++    In an \.{OFM} file, eight bytes are used, two bytes for each field.
++
++    In a kern step, an additional space equal to |kern[256 * (op_byte-128) +
++    remainder]| is inserted between the current character and |next_char|. This
++    amount is often negative, so that the characters are brought closer together
++    by kerning; but it might be positive.
++
++    There are eight kinds of ligature steps, having |op_byte| codes $4a+2b+c$
++    where $0\le a\le b+c$ and $0\le b,c\le1$. The character whose code is
++    |remainder| is inserted between the current character and |next_char|; then
++    the current character is deleted if $b=0$, and |next_char| is deleted if
++    $c=0$; then we pass over $a$~characters to reach the next current character
++    (which may have a ligature/kerning program of its own).
++
++    If the very first instruction of the |lig_kern| array has |skip_byte=255|,
++    the |next_char| byte is the so-called right boundary character of this font;
++    the value of |next_char| need not lie between |bc| and~|ec|. If the very last
++    instruction of the |lig_kern| array has |skip_byte=255|, there is a special
++    ligature/kerning program for a left boundary character, beginning at location
++    |256*op_byte+remainder|. The interpretation is that \TeX\ puts implicit
++    boundary characters before and after each consecutive string of characters
++    from the same font. These implicit characters do not appear in the output,
++    but they can affect ligatures and kerning.
++
++    If the very first instruction of a character's |lig_kern| program has
++    |skip_byte>128|, the program actually begins in location
++    |256*op_byte+remainder|. This feature allows access to large |lig_kern|
++    arrays, because the first instruction must otherwise appear in a location
++    |<=255| in a \TFM\file, |<=65535| in an \.{OFM} file.
++
++    Any instruction with |skip_byte>128| in the |lig_kern| array must satisfy the
++    condition $$\hbox{|256*op_byte+remainder<nl|.}$$ If such an instruction is
++    encountered during normal program execution, it denotes an unconditional
++    halt; no ligature or kerning command is performed.
++
++    Extensible characters are specified by an |@!extensible_recipe|, which
++    consists of four bytes in a \TFM\file, called |@!top|, |@!mid|, |@!bot|,
++    and |@!rep| (in this order). In an \.{OFM} file, each field takes two bytes,
++    for eight in total. These bytes are the character codes of individual pieces
++    used to build up a large symbol. If |top|, |mid|, or |bot| are zero, they are
++    not present in the built-up result. For example, an extensible vertical line
++    is like an extensible bracket, except that the top and bottom pieces are
++    missing.
++
++    Let $T$, $M$, $B$, and $R$ denote the respective pieces, or an empty box if
++    the piece isn't present. Then the extensible characters have the form
++    $TR^kMR^kB$ from top to bottom, for some |k>=0|, unless $M$ is absent; in the
++    latter case we can have $TR^kB$ for both even and odd values of~|k|. The
++    width of the extensible character is the width of $R$; and the
++    height-plus-depth is the sum of the individual height-plus-depths of the
++    components used, since the pieces are butted together in a vertical list.
++
++    The final portion of a \TFM\file is the |param| array, which is another
++    sequence of |fix_word| values.
++
++    \startitemize
++
++    \startitem
++        |param[1]=slant| is the amount of italic slant, which is used to help
++        position accents. For example, |slant=.25| means that when you go up one
++        unit, you also go .25 units to the right. The |slant| is a pure number;
++        it's the only |fix_word| other than the design size itself that is not
++        scaled by the design size.
++    \stopitem
++
++    \startitem
++        |param[2]=space| is the normal spacing between words in text. Note that
++        character |" "| in the font need not have anything to do with blank
++        spaces.
++    \stopitem
++
++    \startitem
++        |param[3]=space_stretch| is the amount of glue stretching between words.
++    \stopitem
++
++    \startitem
++        |param[4]=space_shrink| is the amount of glue shrinking between words.
++    \stopitem
++
++    \startitem
++        |param[5]=x_height| is the size of one ex in the font; it is also the
++        height of letters for which accents don't have to be raised or lowered.
++    \stopitem
++
++    \startitem
++        |param[6]=quad| is the size of one em in the font.
++    \stopitem
++

++    parameter information, which is explained later.

++    There are programs called \.{TFtoPL} and \.{PLtoTF} that convert between the

++    These programs contain extensive diagnostic information, so \TeX\ does not
++    have to bother giving precise details about why it rejects a particular

++The function |readimage| performs some basic initializations. Then it looks at
++the file extension to determine the image type and calls specific code/functions.
++The main disadvantage is that standard file extensions have to be used, otherwise
+ pdfTeX is not able to detect the correct image type. The patch now looks at the
+ file header first regardless of the file extension. This is implemented in
+ function |check_type_by_header|. If this check fails, the traditional test of
+ standard file extension is tried, done in function |check_type_by_extension|.
+ 
+-Magic headers:
+-
+-* "PNG (Portable Network Graphics) Specification", Version 1.2
+-  (http://www.libpng.org/pub/png):
+-
+-   3.1. PNG file signature
+-
+-      The first eight bytes of a PNG file always contain the following
+-      (decimal) values: 137 80 78 71 13 10 26 10
+-
+-Translation to C: |"\x89PNG\r\n\x1A\n"|
+-
+-* "JPEG File Interchange Format", Version 1.02:
+-
+-  * you can identify a JFIF file by looking for the following sequence:
+-    X'FF', SOI X'FF', APP0, <2 bytes to be skipped>, "JFIF", X'00'.
+-
+-Function |check_type_by_header| only looks at the first two bytes: |"\xFF\xD8"|

+-  * The "implementation notes" say:
+-
+-   3.4.1,  File Header
+-     12. Acrobat viewers require only that the header appear somewhere within the
+-         first 1024 bytes of the file.
+-     13. Acrobat viewers will also accept a header of the form \%!PS-Adobe-N.n PDF-M.m
+-
+-The check in function |check_type_by_header| only implements the first issue. The
+-implementation notes are not considered. Therefore files with garbage at start of
+-file must have the standard extension.

+-When the line-breaking routine is unable to find a feasible sequence of
+-breakpoints, it makes a second pass over the paragraph, attempting to hyphenate
+-the hyphenatable words. The goal of hyphenation is to insert discretionary
+-material into the paragraph so that there are more potential places to break.
+-
+-The general rules for hyphenation are somewhat complex and technical, because we
+-want to be able to hyphenate words that are preceded or followed by punctuation
+-marks, and because we want the rules to work for languages other than English. We
+-also must contend with the fact that hyphens might radically alter the ligature
+-and kerning structure of a word.
+-
+-A sequence of characters will be considered for hyphenation only if it belongs to
+-a ``potentially hyphenatable part'' of the current paragraph. This is a sequence
+-of nodes $p_0p_1\ldots p_m$ where $p_0$ is a glue node, $p_1\ldots p_{m-1}$ are
+-either character or ligature or whatsit or implicit kern nodes, and $p_m$ is a
+-glue or penalty or insertion or adjust or mark or whatsit or explicit kern node.
+-(Therefore hyphenation is disabled by boxes, math formulas, and discretionary
+-nodes already inserted by the user.) The ligature nodes among $p_1\ldots p_{m-1}$
+-are effectively expanded into the original non-ligature characters; the kern
+-nodes and whatsits are ignored. Each character |c| is now classified as either a
+-nonletter (if |lc_code(c)=0|), a lowercase letter (if |lc_code(c)=c|), or an
+-uppercase letter (otherwise); an uppercase letter is treated as if it were
+-|lc_code(c)| for purposes of hyphenation. The characters generated by $p_1\ldots
+-p_{m-1}$ may begin with nonletters; let $c_1$ be the first letter that is not in
+-the middle of a ligature. Whatsit nodes preceding $c_1$ are ignored; a whatsit
+-found after $c_1$ will be the terminating node $p_m$. All characters that do not
+-have the same font as $c_1$ will be treated as nonletters. The |hyphen_char| for
+-that font must be between 0 and 255, otherwise hyphenation will not be attempted.
+-\TeX\ looks ahead for as many consecutive letters $c_1\ldots c_n$ as possible;
+-however, |n| must be less than 64, so a character that would otherwise be
+-$c_{64}$ is effectively not a letter. Furthermore $c_n$ must not be in the middle
+-of a ligature. In this way we obtain a string of letters $c_1\ldots c_n$ that are
+-generated by nodes $p_a\ldots p_b$, where |1<=a<=b+1<=m|. If |n>=l_hyf+r_hyf|,
+-this string qualifies for hyphenation; however, |uc_hyph| must be positive, if
+-$c_1$ is uppercase.
+-
+-The hyphenation process takes place in three stages. First, the candidate
+-sequence $c_1\ldots c_n$ is found; then potential positions for hyphens are
+-determined by referring to hyphenation tables; and finally, the nodes $p_a\ldots
+-p_b$ are replaced by a new sequence of nodes that includes the discretionary
+-breaks found.
+-
+-Fortunately, we do not have to do all this calculation very often, because of the
+-way it has been taken out of \TeX's inner loop. For example, when the second
+-edition of the author's 700-page book {\sl Seminumerical Algorithms} was typeset
+-by \TeX, only about 1.2 hyphenations needed to be @^Knuth, Donald Ervin@> tried
+-per paragraph, since the line breaking algorithm needed to use two passes on only
+-about 5 per cent of the paragraphs.
+-
+-When a word been set up to contain a candidate for hyphenation, \TeX\ first looks
+-to see if it is in the user's exception dictionary. If not, hyphens are inserted
+-based on patterns that appear within the given word, using an algorithm due to
+-Frank~M. Liang. @^Liang, Franklin Mark@>
+-
+-@ This is incompatible with TEX because the first word of a paragraph can be
+-hyphenated, but most european users seem to agree that prohibiting hyphenation
+-there was not the best idea ever.

+-@ Compute the ID string as per PDF1.4 9.3:
+-
+-File identifers are defined by the optional ID entry in a PDF file's trailer
+-dictionary (see Section 3.4.4, "File Trailer"; see also implementation note 105
+-in Appendix H). The value of this entry is an array of two strings. The first
+-string is a permanent identifier based on the contents of the file at the time it
+-was originally created, and does not change when the file is incrementally
+-updated. The second string is a changing identifier based on the file's contents
+-at the time it was last updated. When a file is first written, both identifiers
+-are set to the same value. If both identifiers match when a file reference is
+-resolved, it is very likely that the correct file has been found; if only the
+-first identifier matches, then a different version of the correct file has been
+-found. To help ensure the uniqueness of file identifiers, it is recommend that
+-they be computed using a message digest algorithm such as MD5 (described in
+-Internet RFC 1321, The MD5 Message-Digest Algorithm; see the Bibliography), using
+-the following information (see implementation note 106 in Appendix H): - The
+-current time
+-
+-- A string representation of the file's location, usually a pathname
+-- The size of the file in bytes
+-- The values of all entries in the file's document information
+-  dictionary (see Section 9.2.1,  Document Information Dictionary )
+-
+-This stipulates only that the two IDs must be identical when the file is created
+-and that they should be reasonably unique. Since it's difficult to get the file
+-size at this point in the execution of pdfTeX and scanning the info dict is also
+-difficult, we start with a simpler implementation using just the first two items.

+-@ Print the /CreationDate entry.
+-
+-PDF Reference, third edition says about the expected date format:
+-
+-3.8.2 Dates
+-
+-PDF defines a standard date format, which closely follows that of the
+-international standard ASN.1 (Abstract Syntax Notation One), defined in ISO/IEC
+-8824 (see the Bibliography). A date is a string of the form
+-
+-(D:YYYYMMDDHHmmSSOHH'mm')
+-
+-where
+-
+-YYYY  is the year
+-MM    is the month
+-DD    is the day (01-31)
+-HH    is the hour (00-23)
+-mm    is the minute (00-59)
+-SS    is the second (00-59)
+-O     is the relationship of local time to Universal Time (UT), denoted by one
+-      of the characters +, -, or Z (see below)
+-HH    followed by ' is the absolute value of the offset from UT in hours (00-23)
+-mm    followed by ' is the absolute value of the offset from UT in minutes (00-59)
+-
+-The apostrophe character (') after HH and mm is part of the syntax. All fields
+-after the year are optional. (The prefix D:, although also optional, is strongly
+-recommended.) The default values for MM and DD are both 01; all other numerical
+-fields default to zero values. A plus sign (+) as the value of the O field
+-signifies that local time is later than UT, a minus sign (-) that local time is
+-earlier than UT, and the letter Z that local time is equal to UT. If no UT
+-information is specified, the relationship of the specified time to UT is
+-considered to be unknown. Whether or not the time zone is known, the rest of the
+-date should be specified in local time.

+-For example, December 23, 1998, at 7:52 PM, U.S. Pacific Standard Time, is

++
++    It's sort of a miracle whenever \.{\\halign} and \.{\\valign} work, because
++    they cut across so many of the control structures of \TeX. Therefore the
++    present page is probably not the best place for a beginner to start reading
++    this program; it is better to master everything else first.
++
++    Let us focus our thoughts on an example of what the input might be, in order
++    to get some idea about how the alignment miracle happens. The example doesn't
++    do anything useful, but it is sufficiently general to indicate all of the
++    special cases that must be dealt with; please do not be disturbed by its
++    apparent complexity and meaninglessness.
++
++    \starttyping
++    \tabskip 2pt plus 3pt
++    \halign to 300pt{u1#v1&
++    \hskip 50pt \tabskip 1pt plus 1fil u2#v2&
++    \hskip 50pt u3#v3\cr
++    \hskip 25pt a1&\omit a2&\vrule\cr
++    \hskip 25pt \noalign\{\vskip 3pt}
++    \hskip 25pt b1\span b2\cr
++    \hskip 25pt \omit&c2\span\omit\cr}
++    \stoptyping
++
++    Here's what happens:
++
++    \startitemize
++
++        \startitem
++            When `\.{\\halign to 300pt\{}' is scanned, the |scan_spec| routine
++            places the 300pt dimension onto the |save_stack|, and an
++            |align_group| code is placed above it. This will make it possible to
++            complete the alignment when the matching `\.\}' is found.
++        \stopitem
++
++        \startitem
++            The preamble is scanned next. Macros in the preamble are not
++            expanded, except as part of a tabskip specification. For example, if
++            \.{u2} had been a macro in the preamble above, it would have been
++            expanded, since \TeX\ must look for `\.{minus...}' as part of the
++            tabskip glue. A ``preamble list'' is constructed based on the user's
++            preamble; in our case it contains the following seven items:
++
++            \starttabulate
++            \NC \type{\glue 2pt plus 3pt}              \NC the tabskip preceding column 1      \NC \NR
++            \NC \type{\alignrecord} of width $-\infty$ \NC preamble info for column 1          \NC \NR
++            \NC \type{\glue 2pt plus 3pt}              \NC the tabskip between columns 1 and 2 \NC \NR
++            \NC \type{\alignrecord} of width $-\infty$ \NC preamble info for column 2          \NC \NR
++            \NC \type{\glue 1pt plus 1fil}             \NC the tabskip between columns 2 and 3 \NC \NR
++            \NC \type{\alignrecord} of width $-\infty$ \NC preamble info for column 3          \NC \NR
++            \NC \type{\glue 1pt plus 1fil}             \NC the tabskip following column 3      \NC \NR
++            \stoptabulate
++
++            These ``alignrecord'' entries have the same size as an |unset_node|,
++            since they will later be converted into such nodes. These alignrecord
++            nodes have no |depth| field; this is split into |u_part| and
++            |v_part|, and they point to token lists for the templates of the
++            alignment. For example, the |u_part| field in the first alignrecord
++            points to the token list `\.{u1}', i.e., the template preceding the
++            `\.\#' for column~1. Furthermore, They have a |span_ptr| instead of a
++            |node_attr| field, and these |span_ptr| fields are initially set to
++            the value |end_span|, for reasons explained below.
++        \stopitem
++
++        \startitem
++            \TeX\ now looks at what follows the \.{\\cr} that ended the preamble.
++            It is not `\.{\\noalign}' or `\.{\\omit}', so this input is put back
++            to be read again, and the template `\.{u1}' is fed to the scanner.
++            Just before reading `\.{u1}', \TeX\ goes into restricted horizontal
++            mode. Just after reading `\.{u1}', \TeX\ will see `\.{a1}', and then
++            (when the {\.\&} is sensed) \TeX\ will see `\.{v1}'. Then \TeX\ scans
++            an |endv| token, indicating the end of a column. At this point an
++            |unset_node| is created, containing the contents of the current hlist
++            (i.e., `\.{u1a1v1}'). The natural width of this unset node replaces
++            the |width| field of the alignrecord for column~1; in general, the
++            alignrecords will record the maximum natural width that has occurred
++            so far in a given column.
++        \stopitem
++
++        \startitem
++            Since `\.{\\omit}' follows the `\.\&', the templates for column~2 are
++            now bypassed. Again \TeX\ goes into restricted horizontal mode and
++            makes an |unset_node| from the resulting hlist; but this time the
++            hlist contains simply `\.{a2}'. The natural width of the new unset
++            box is remembered in the |width| field of the alignrecord for
++            column~2.
++        \stopitem
++
++        \startitem
++            A third |unset_node| is created for column 3, using essentially the
++            mechanism that worked for column~1; this unset box contains
++            `\.{u3\\vrule v3}'. The vertical rule in this case has running
++            dimensions that will later extend to the height and depth of the
++            whole first row, since each |unset_node| in a row will eventually
++            inherit the height and depth of its enclosing box.
++        \stopitem
++
++        \startitem
++            The first row has now ended; it is made into a single unset box
++            comprising the following seven items:
++
++            \starttyping
++            \glue 2pt plus 3pt
++            \unsetbox for 1 column: u1a1v1
++            \glue 2pt plus 3pt
++            \unsetbox for 1 column: a2
++            \glue 1pt plus 1fil
++            \unsetbox for 1 column: u3\vrule v3
++            \glue 1pt plus 1fil
++            \stoptyping
++
++            The width of this unset row is unimportant, but it has the correct
++            height and depth, so the correct baselineskip glue will be computed
++            as the row is inserted into a vertical list.
++        \stopitem
++
++        \startitem
++            Since `\.{\\noalign}' follows the current \.{\\cr}, \TeX\ appends
++            additional material (in this case \.{\\vskip 3pt}) to the vertical
++            list. While processing this material, \TeX\ will be in internal
++            vertical mode, and |no_align_group| will be on |save_stack|.
++        \stopitem
++
++        \startitem
++            The next row produces an unset box that looks like this:
++
++            \starttyping
++            \glue 2pt plus 3pt
++            \unsetbox for 2 columns: u1b1v1u2b2v2
++            \glue 1pt plus 1fil
++            \unsetbox for 1 column: {(empty)}
++            \glue 1pt plus 1fil
++            \stoptyping
++
++            The natural width of the unset box that spans columns 1~and~2 is
++            stored in a ``span node,'' which we will explain later; the
++            |span_ptr| field of the alignrecord for column~1 now points to the
++            new span node, and the |span_ptr| of the span node points to
++            |end_span|.
++        \stopitem
++
++        \startitem
++
++            The final row produces the unset box
++
++            \starttyping
++            \glue 2pt plus 3pt\cr
++            \unsetbox for 1 column: {(empty)}
++            \glue 2pt plus 3pt\cr
++            \unsetbox for 2 columns: u2c2v2
++            \glue 1pt plus 1fil
++            \stoptyping
++
++            A new span node is attached to the alignrecord for column 2.
++        \stopitem
++
++        \startitem
++            The last step is to compute the true column widths and to change all
++            the unset boxes to hboxes, appending the whole works to the vertical
++            list that encloses the \.{\\halign}. The rules for deciding on the
++            final widths of each unset column box will be explained below.
++        \stopitem
++
++    \stopitemize
++
++    Note that as \.{\\halign} is being processed, we fearlessly give up control
++    to the rest of \TeX. At critical junctures, an alignment routine is called
++    upon to step in and do some little action, but most of the time these
++    routines just lurk in the background. It's something like post-hypnotic
++    suggestion.
++
++    We have mentioned that alignrecords contain no |height| or |depth| fields.
++    Their |glue_sign| and |glue_order| are pre-empted as well, since it is
++    necessary to store information about what to do when a template ends. This
++    information is called the |extra_info| field.

++    A span node is a 3-word record containing |width|, |span_span|, and

++
++        It's time now to dismantle the preamble list and to compute the
++        column widths. Let $w_{ij}$ be the maximum of the natural widths of
++        all entries that span columns $i$ through $j$, inclusive. The
++        alignrecord for column~$i$ contains $w_{ii}$ in its |width| field,
++        and there is also a linked list of the nonzero $w_{ij}$ for
++        increasing $j$, accessible via the |info| field; these span nodes
++        contain the value $j-i+|min_quarterword|$ in their |link| fields. The
++        values of $w_{ii}$ were initialized to |null_flag|, which we regard
++        as $-\infty$.
++
++        The final column widths are defined by the formula $$w_j=\max_{1\L
++        i\L j}\biggl( w_{ij}-\sum_{i\L k<j}(t_k+w_k)\biggr),$$ where $t_k$ is
++        the natural width of the tabskip glue between columns $k$ and~$k+1$.
++        However, if $w_{ij}=-\infty$ for all |i| in the range |1<=i<=j|
++        (i.e., if every entry that involved column~|j| also involved
++        column~|j+1|), we let $w_j=0$, and we zero out the tabskip glue after
++        column~|j|.
++
++        \TeX\ computes these values by using the following scheme: First
++        $w_1=w_{11}$. Then replace $w_{2j}$ by $\max(w_{2j},w_{1j}-t_1-w_1)$,
++        for all $j>1$. Then $w_2=w_{22}$. Then replace $w_{3j}$ by
++        $\max(w_{3j},w_{2j}-t_2-w_2)$ for all $j>2$; and so on. If any $w_j$
++        turns out to be $-\infty$, its value is changed to zero and so is the
++        next tabskip.

+-@ It's sort of a miracle whenever \.{\\halign} and \.{\\valign} work, because
+-they cut across so many of the control structures of \TeX.
+-
+-Therefore the present page is probably not the best place for a beginner to
+-start reading this program; it is better to master everything else first.
+-
+-Let us focus our thoughts on an example of what the input might be, in order
+-to get some idea about how the alignment miracle happens. The example doesn't
+-do anything useful, but it is sufficiently general to indicate all of the
+-special cases that must be dealt with; please do not be disturbed by its
+-apparent complexity and meaninglessness.
+-$$\vbox{\halign{\.{#}\hfil\cr
+-{}\\tabskip 2pt plus 3pt\cr
+-{}\\halign to 300pt\{u1\#v1\&\cr
+-\hskip 50pt\\tabskip 1pt plus 1fil u2\#v2\&\cr

+-\hskip 25pt \\noalign\{\\vskip 3pt\}\cr
+-\hskip 25pt b1\\span b2\\cr\cr
+-\hskip 25pt \\omit\&c2\\span\\omit\\cr\}\cr}}$$
+-Here's what happens:
+-
+-\yskip
+-(0) When `\.{\\halign to 300pt\{}' is scanned, the |scan_spec| routine
+-places the 300pt dimension onto the |save_stack|, and an |align_group|
+-code is placed above it. This will make it possible to complete the alignment
+-when the matching `\.\}' is found.
+-
+-(1) The preamble is scanned next. Macros in the preamble are not expanded,
+-@^preamble@>
+-except as part of a tabskip specification. For example, if \.{u2} had been
+-a macro in the preamble above, it would have been expanded, since \TeX\
+-must look for `\.{minus...}' as part of the tabskip glue. A ``preamble list''
+-is constructed based on the user's preamble; in our case it contains the
+-following seven items:
+-$$\vbox{\halign{\.{#}\hfil\qquad&(#)\hfil\cr
+-{}\\glue 2pt plus 3pt&the tabskip preceding column 1\cr
+-{}\\alignrecord, width $-\infty$&preamble info for column 1\cr
+-{}\\glue 2pt plus 3pt&the tabskip between columns 1 and 2\cr
+-{}\\alignrecord, width $-\infty$&preamble info for column 2\cr
+-{}\\glue 1pt plus 1fil&the tabskip between columns 2 and 3\cr
+-{}\\alignrecord, width $-\infty$&preamble info for column 3\cr
+-{}\\glue 1pt plus 1fil&the tabskip following column 3\cr}}$$
+-These ``alignrecord'' entries have the same size as an |unset_node|,
+-since they will later be converted into such nodes. These alignrecord
+-nodes have no |depth| field; this is split into |u_part| and |v_part|,
+-and they point to token lists for the templates of the alignment. For
+-example, the |u_part| field in the first alignrecord points to the
+-token list `\.{u1}', i.e., the template preceding the `\.\#' for
+-column~1.  Furthermore, They have a |span_ptr| instead of a |node_attr|
+-field, and these |span_ptr| fields are initially set to the value
+-|end_span|, for reasons explained below.
+-
+-(2) \TeX\ now looks at what follows the \.{\\cr} that ended the preamble.
+-It is not `\.{\\noalign}' or `\.{\\omit}', so this input is put back to
+-be read again, and the template `\.{u1}' is fed to the scanner. Just
+-before reading `\.{u1}', \TeX\ goes into restricted horizontal mode.
+-Just after reading `\.{u1}', \TeX\ will see `\.{a1}', and then (when the
+-{\.\&} is sensed) \TeX\ will see `\.{v1}'. Then \TeX\ scans an |endv|
+-token, indicating the end of a column. At this point an |unset_node| is
+-created, containing the contents of the current hlist (i.e., `\.{u1a1v1}').
+-The natural width of this unset node replaces the |width| field of the
+-alignrecord for column~1; in general, the alignrecords will record the
+-maximum natural width that has occurred so far in a given column.
+-
+-(3) Since `\.{\\omit}' follows the `\.\&', the templates for column~2
+-are now bypassed. Again \TeX\ goes into restricted horizontal mode and
+-makes an |unset_node| from the resulting hlist; but this time the
+-hlist contains simply `\.{a2}'. The natural width of the new unset box
+-is remembered in the |width| field of the alignrecord for column~2.
+-
+-(4) A third |unset_node| is created for column 3, using essentially the
+-mechanism that worked for column~1; this unset box contains `\.{u3\\vrule
+-v3}'. The vertical rule in this case has running dimensions that will later
+-extend to the height and depth of the whole first row, since each |unset_node|
+-in a row will eventually inherit the height and depth of its enclosing box.
+-
+-(5) The first row has now ended; it is made into a single unset box
+-comprising the following seven items:
+-$$\vbox{\halign{\hbox to 325pt{\qquad\.{#}\hfil}\cr
+-{}\\glue 2pt plus 3pt\cr
+-{}\\unsetbox for 1 column: u1a1v1\cr
+-{}\\glue 2pt plus 3pt\cr
+-{}\\unsetbox for 1 column: a2\cr
+-{}\\glue 1pt plus 1fil\cr
+-{}\\unsetbox for 1 column: u3\\vrule v3\cr
+-{}\\glue 1pt plus 1fil\cr}}$$
+-The width of this unset row is unimportant, but it has the correct height
+-and depth, so the correct baselineskip glue will be computed as the row
+-is inserted into a vertical list.
+-
+-(6) Since `\.{\\noalign}' follows the current \.{\\cr}, \TeX\ appends
+-additional material (in this case \.{\\vskip 3pt}) to the vertical list.
+-While processing this material, \TeX\ will be in internal vertical
+-mode, and |no_align_group| will be on |save_stack|.
+-
+-(7) The next row produces an unset box that looks like this:
+-$$\vbox{\halign{\hbox to 325pt{\qquad\.{#}\hfil}\cr
+-{}\\glue 2pt plus 3pt\cr
+-{}\\unsetbox for 2 columns: u1b1v1u2b2v2\cr
+-{}\\glue 1pt plus 1fil\cr
+-{}\\unsetbox for 1 column: {\rm(empty)}\cr
+-{}\\glue 1pt plus 1fil\cr}}$$
+-The natural width of the unset box that spans columns 1~and~2 is stored
+-in a ``span node,'' which we will explain later; the |span_ptr| field of the
+-alignrecord for column~1 now points to the new span node, and the |span_ptr|
+-of the span node points to |end_span|.
+-
+-(8) The final row produces the unset box
+-$$\vbox{\halign{\hbox to 325pt{\qquad\.{#}\hfil}\cr
+-{}\\glue 2pt plus 3pt\cr
+-{}\\unsetbox for 1 column: {\rm(empty)}\cr
+-{}\\glue 2pt plus 3pt\cr
+-{}\\unsetbox for 2 columns: u2c2v2\cr
+-{}\\glue 1pt plus 1fil\cr}}$$
+-A new span node is attached to the alignrecord for column 2.
+-
+-(9) The last step is to compute the true column widths and to change all the
+-unset boxes to hboxes, appending the whole works to the vertical list that
+-encloses the \.{\\halign}. The rules for deciding on the final widths of
+-each unset column box will be explained below.
+-
+-\yskip\noindent
+-Note that as \.{\\halign} is being processed, we fearlessly give up control
+-to the rest of \TeX. At critical junctures, an alignment routine is
+-called upon to step in and do some little action, but most of the time
+-these routines just lurk in the background. It's something like
+-post-hypnotic suggestion.
+-
+-@ We have mentioned that alignrecords contain no |height| or |depth| fields.
+-Their |glue_sign| and |glue_order| are pre-empted as well, since it
+-is necessary to store information about what to do when a template ends.
+-This information is called the |extra_info| field.
+-
+-@c
+-/* could be in texnodes.h, but documented here*/
+-
+-#define u_part(A)     vlink((A)+depth_offset) /* pointer to \<u_j> token list */
+-#define v_part(A)     vinfo((A)+depth_offset) /* pointer to \<v_j> token list */
+-#define span_ptr(A)   vinfo((A)+1)            /* column spanning list */
+-#define extra_info(A) vinfo((A)+list_offset)  /* info to remember during template */
+-
+-@ Alignments can occur within alignments, so a small stack is used to access
+-the alignrecord information. At each level we have a |preamble| pointer,
+-indicating the beginning of the preamble list; a |cur_align| pointer,
+-indicating the current position in the preamble list; a |cur_span| pointer,
+-indicating the value of |cur_align| at the beginning of a sequence of
+-spanned columns; a |cur_loop| pointer, indicating the tabskip glue before
+-an alignrecord that should be copied next if the current list is extended;
+-and the |align_state| variable, which indicates the nesting of braces so
+-that \.{\\cr} and \.{\\span} and tab marks are properly intercepted.
+-There also are pointers |cur_head| and |cur_tail| to the head and tail
+-of a list of adjustments being moved out from horizontal mode to
+-vertical~mode, and alike |cur_pre_head| and |cur_pre_tail| for pre-adjust
+-lists.
+-
+-The current values of these nine quantities appear in global variables;
+-when they have to be pushed down, they are stored in 6-word nodes, and
+-|align_ptr| points to the topmost such node.
+-

+-/* The |align_state| and |preamble| variables are initialized elsewhere. */
+-
+-@ Alignment stack maintenance is handled by a pair of trivial routines
+-called |push_alignment| and |pop_alignment|.
+-
+-(HH:) It makes not much sense to add support for an \.{attr} keyword to
+-\.{\\halign} and \.{\\valign} because then we need to decide if we tag
+-rows or cells or both or come up with \.{cellattr} and \.{rowattr} and
+-such. But then it even makes sense to have explicit commands (in addition
+-to the seperator) to tags individual cells. Too muss hassle for now and the
+-advantages are not that large.

+-@ \TeX\ has eight procedures that govern alignments: |init_align| and
+-|fin_align| are used at the very beginning and the very end; |init_row| and
+-|fin_row| are used at the beginning and end of individual rows; |init_span|
+-is used at the beginning of a sequence of spanned columns (possibly involving
+-only one column); |init_col| and |fin_col| are used at the beginning and
+-end of individual columns; and |align_peek| is used after \.{\\cr} to see
+-whether the next item is \.{\\noalign}.
+-
+-We shall consider these routines in the order they are first used during
+-the course of a complete \.{\\halign}, namely |init_align|, |align_peek|,

+-
+-
+-@ The preamble is copied directly, except that \.{\\tabskip} causes a change

+-token survives in the preamble and the `\.{\\tabskip}' defines new

+-@ A span node is a 3-word record containing |width|, |span_span|, and
+-|span_ptr| fields. The |span_span| field indicates the number of
+-spanned columns; the |span_ptr| field points to a span node for the same
+-starting column, having a greater extent of spanning, or to
+-|end_span|, which has the largest possible |span_span| field; the |width|
+-field holds the largest natural width corresponding to a particular
+-set of spanned columns.
+-
+-A list of the maximum widths so far, for spanned columns starting at a
+-given column, begins with the |span_ptr| field of the alignrecord for
+-that column. The code has to make sure that there is room for
+-|span_ptr| in both the alignrecord and the span nodes, which is why

+-these span nodes contain the value $j-i+|min_quarterword|$ in their

+-we regard as $-\infty$.
+-
+-The final column widths are defined by the formula
+-$$w_j=\max_{1\L i\L j}\biggl( w_{ij}-\sum_{i\L k<j}(t_k+w_k)\biggr),$$
+-where $t_k$ is the natural width of the tabskip glue between columns
+-$k$ and~$k+1$. However, if $w_{ij}=-\infty$ for all |i| in the range
+-|1<=i<=j| (i.e., if every entry that involved column~|j| also involved
+-column~|j+1|), we let $w_j=0$, and we zero out the tabskip glue after
+-column~|j|.
+-
+-\TeX\ computes these values by using the following scheme: First $w_1=w_{11}$.
+-Then replace $w_{2j}$ by $\max(w_{2j},w_{1j}-t_1-w_1)$, for all $j>1$.
+-Then $w_2=w_{22}$. Then replace $w_{3j}$ by $\max(w_{3j},w_{2j}-t_2-w_2)$
+-for all $j>2$; and so on. If any $w_j$ turns out to be $-\infty$, its
+-value is changed to zero and so is the next tabskip.

++The principal computations performed by \TeX\ are done entirely in terms of
++integers less than $2^{31}$ in magnitude; and divisions are done only when both
++dividend and divisor are nonnegative. Thus, the arithmetic specified in this
++program can be carried out in exactly the same way on a wide variety of
++computers, including some small ones. Why? Because the arithmetic calculations
++need to be spelled out precisely in order to guarantee that \TeX\ will produce
++identical output on different machines. If some quantities were rounded
++differently in different implementations, we would find that line breaks and even
++page breaks might occur in different places. Hence the arithmetic of \TeX\ has
++been designed with care, and systems that claim to be implementations of \TeX82
++should follow precisely the @:TeX82}{\TeX82@> calculations as they appear in the
++present program.
++
++Actually there are three places where \TeX\ uses |div| with a possibly negative
++numerator. These are harmless; see |div| in the index. Also if the user sets the
++\.{\\time} or the \.{\\year} to a negative value, some diagnostic information
++will involve negative-numerator division. The same remarks apply for |mod| as

++Physical sizes that a \TeX\ user specifies for portions of documents are
++represented internally as scaled points. Thus, if we define an `sp' (scaled
++@^sp@> point) as a unit equal to $2^{-16}$ printer's points, every dimension
++inside of \TeX\ is an integer number of sp. There are exactly 4,736,286.72 sp per
++inch. Users are not allowed to specify dimensions larger than $2^{30}-1$ sp,
++which is a distance of about 18.892 feet (5.7583 meters); two such quantities can
++be added without overflow on a 32-bit computer.
++
++The present implementation of \TeX\ does not check for overflow when @^overflow
++in arithmetic@> dimensions are added or subtracted. This could be done by
++inserting a few dozen tests of the form `\ignorespaces|if x>=010000000000 then
++@t\\{report\_overflow}@>|', but the chance of overflow is so remote that such
++tests do not seem worthwhile.
++
++\TeX\ needs to do only a few arithmetic operations on scaled quantities, other
++than addition and subtraction, and the following subroutines do most of the work.
++A single computation might use several subroutine calls, and it is desirable to
++avoid producing multiple error messages in case of arithmetic overflow; so the

++This section is (almost) straight from MetaPost. I (Taco) had to change the types
++(use |integer| instead of |fraction|), but that should not have any influence on
++the actual calculations (the original comments refer to quantities like
++|fraction_four| ($2^{30}$), and that is the same as the numeric representation of
++|max_dimen|).
++
++I've copied the low-level variables and routines that are needed, but only those
++(e.g. |m_log|), not the accompanying ones like |m_exp|. Most of the following
++low-level numeric routines are only needed within the calculation of |norm_rand|.
++I've been forced to rename |make_fraction| to |make_frac| because TeX already has
++a routine by that name with a wholly different function (it creates a
++|fraction_noad| for math typesetting)
++
++And now let's complete our collection of numeric utility routines by considering
++random number generation. \MP{} generates pseudo-random numbers with the additive
++scheme recommended in Section 3.6 of {\sl The Art of Computer Programming};
++however, the results are random fractions between 0 and |fraction_one-1|,
++inclusive.
++
++There's an auxiliary array |randoms| that contains 55 pseudo-random fractions.
++Using the recurrence $x_n=(x_{n-55}-x_{n-31})\bmod 2^{28}$, we generate batches
++of 55 new $x_n$'s at a time by calling |new_randoms|. The global variable

++The |make_frac| routine produces the |fraction| equivalent of |p/q|, given
++integers |p| and~|q|; it computes the integer
++$f=\lfloor2^{28}p/q+{1\over2}\rfloor$, when $p$ and $q$ are positive. If |p| and
++|q| are both of the same scaled type |t|, the ``type relation''
++|make_frac(t,t)=fraction| is valid; and it's also possible to use the subroutine
++``backwards,'' using the relation |make_frac(t,fraction)=t| between scaled types.
++
++If the result would have magnitude $2^{31}$ or more, |make_frac| sets
++|arith_error:=true|. Most of \MP's internal computations have been designed to
++avoid this sort of error.
++
++If this subroutine were programmed in assembly language on a typical machine, we
++could simply compute |(@t$2^{28}$@>*p)div q|, since a double-precision product
++can often be input to a fixed-point division instruction. But when we are
++restricted to PASCAL arithmetic it is necessary either to resort to
++multiple-precision maneuvering or to use a simple but slow iteration. The
++multiple-precision technique would be about three times faster than the code
++adopted here, but it would be comparatively long and tricky, involving about
++sixteen additional multiplications and divisions.
++
++This operation is part of \MP's ``inner loop''; indeed, it will consume nearly
++10\%! of the running time (exclusive of input and output) if the code below is
++left unchanged. A machine-dependent recoding will therefore make \MP\ run faster.
++The present implementation is highly portable, but slow; it avoids multiplication
++and division except in the initial stage. System wizards should be careful to
++replace it with a routine that is guaranteed to produce identical results in all
++cases. @^system dependencies@>
++
++As noted below, a few more routines should also be replaced by machine-dependent
++code, for efficiency. But when a procedure is not part of the ``inner loop,''
++such changes aren't advisable; simplicity and robustness are preferable to
++trickery, unless the cost is too high.

+-
+-@ The principal computations performed by \TeX\ are done entirely in terms of
+-integers less than $2^{31}$ in magnitude; and divisions are done only when both
+-dividend and divisor are nonnegative. Thus, the arithmetic specified in this
+-program can be carried out in exactly the same way on a wide variety of
+-computers, including some small ones. Why? Because the arithmetic
+-calculations need to be spelled out precisely in order to guarantee that
+-\TeX\ will produce identical output on different machines. If some
+-quantities were rounded differently in different implementations, we would
+-find that line breaks and even page breaks might occur in different places.
+-Hence the arithmetic of \TeX\ has been designed with care, and systems that
+-claim to be implementations of \TeX82 should follow precisely the
+-@:TeX82}{\TeX82@>
+-calculations as they appear in the present program.
+-
+-(Actually there are three places where \TeX\ uses |div| with a possibly negative
+-numerator. These are harmless; see |div| in the index. Also if the user
+-sets the \.{\\time} or the \.{\\year} to a negative value, some diagnostic
+-information will involve negative-numerator division. The same remarks
+-apply for |mod| as well as for |div|.)
+-
+-Here is a routine that calculates half of an integer, using an
+-unambiguous convention with respect to signed odd numbers.
+-
+-@c
+-int half(int x)
+-{
+-    if (odd(x))
+-        return ((x + 1) / 2);
+-    else
+-        return (x / 2);
+-}
+-
+-
+-@ The following function is used to create a scaled integer from a given decimal
+-fraction $(.d_0d_1\ldots d_{k-1})$, where |0<=k<=17|. The digit $d_i$ is
+-given in |dig[i]|, and the calculation produces a correctly rounded result.
+-
+-@c
+-scaled round_decimals(int k)
+-{                               /* converts a decimal fraction */
+-    int a;                      /* the accumulator */
+-    a = 0;
+-    while (k-- > 0) {
+-        a = (a + dig[k] * two) / 10;
+-    }
+-    return ((a + 1) / 2);
+-}
+-
+-
+-@ Conversely, here is a procedure analogous to |print_int|. If the output
+-of this procedure is subsequently read by \TeX\ and converted by the
+-|round_decimals| routine above, it turns out that the original value will
+-be reproduced exactly; the ``simplest'' such decimal number is output,
+-but there is always at least one digit following the decimal point.
+-
+-The invariant relation in the \&{repeat} loop is that a sequence of
+-decimal digits yet to be printed will yield the original number if and only if
+-they form a fraction~$f$ in the range $s-\delta\L10\cdot2^{16}f<s$.
+-We can stop if and only if $f=0$ satisfies this condition; the loop will
+-terminate before $s$ can possibly become zero.
+-

+-@ Physical sizes that a \TeX\ user specifies for portions of documents are
+-represented internally as scaled points. Thus, if we define an `sp' (scaled

+-point) as a unit equal to $2^{-16}$ printer's points, every dimension
+-inside of \TeX\ is an integer number of sp. There are exactly
+-4,736,286.72 sp per inch.  Users are not allowed to specify dimensions
+-larger than $2^{30}-1$ sp, which is a distance of about 18.892 feet (5.7583
+-meters); two such quantities can be added without overflow on a 32-bit
+-computer.
+-
+-The present implementation of \TeX\ does not check for overflow when

+-dimensions are added or subtracted. This could be done by inserting a
+-few dozen tests of the form `\ignorespaces|if x>=010000000000 then

+-other than addition and subtraction, and the following subroutines do most of
+-the work. A single computation might use several subroutine calls, and it is
+-desirable to avoid producing multiple error messages in case of arithmetic
+-overflow; so the routines set the global variable |arith_error| to |true|
+-instead of reporting errors directly to the user. Another global variable,
+-|tex_remainder|, holds the remainder after a division.

+-@ When \TeX\ ``packages'' a list into a box, it needs to calculate the

+-so the precise details of rounding, etc., in the glue calculation are not
+-of critical importance for the consistency of results on different computers.
+-
+-We shall use the type |glue_ratio| for such proportionality ratios.
+-A glue ratio should take the same amount of memory as an
+-|integer| (usually 32 bits) if it is to blend smoothly with \TeX's
+-other data structures. Thus |glue_ratio| should be equivalent to
+-|short_real| in some implementations of PASCAL. Alternatively,
+-it is possible to deal with glue ratios using nothing but fixed-point
+-arithmetic; see {\sl TUGboat \bf3},1 (March 1982), 10--27. (But the
+-routines cited there must be modified to allow negative glue ratios.)
+-@^system dependencies@>
+-
+-
+-@ This section is (almost) straight from MetaPost. I had to change
+-the types (use |integer| instead of |fraction|), but that should
+-not have any influence on the actual calculations (the original
+-comments refer to quantities like |fraction_four| ($2^{30}$), and
+-that is the same as the numeric representation of |max_dimen|).
+-
+-I've copied the low-level variables and routines that are needed, but
+-only those (e.g. |m_log|), not the accompanying ones like |m_exp|. Most
+-of the following low-level numeric routines are only needed within the
+-calculation of |norm_rand|. I've been forced to rename |make_fraction|
+-to |make_frac| because TeX already has a routine by that name with
+-a wholly different function (it creates a |fraction_noad| for math
+-typesetting) -- Taco
+-
+-And now let's complete our collection of numeric utility routines
+-by considering random number generation.
+-\MP{} generates pseudo-random numbers with the additive scheme recommended
+-in Section 3.6 of {\sl The Art of Computer Programming}; however, the
+-results are random fractions between 0 and |fraction_one-1|, inclusive.
+-
+-There's an auxiliary array |randoms| that contains 55 pseudo-random
+-fractions. Using the recurrence $x_n=(x_{n-55}-x_{n-31})\bmod 2^{28}$,
+-we generate batches of 55 new $x_n$'s at a time by calling |new_randoms|.
+-The global variable |j_random| tells which element has most recently
+-been consumed.
+-
+-@c
+-static int randoms[55];         /* the last 55 random values generated */
+-static int j_random;            /* the number of unused |randoms| */
+-scaled random_seed;             /* the default random seed */
+-
+-@ A small bit of metafont is needed. 
+-
+-@c
+-#define fraction_half 01000000000       /* $2^{27}$, represents 0.50000000 */
+-#define fraction_one 02000000000        /* $2^{28}$, represents 1.00000000 */
+-#define fraction_four 010000000000      /* $2^{30}$, represents 4.00000000 */
+-#define el_gordo 017777777777   /* $2^{31}-1$, the largest value that \MP\ likes */
+-
+-@ The |make_frac| routine produces the |fraction| equivalent of
+-|p/q|, given integers |p| and~|q|; it computes the integer
+-$f=\lfloor2^{28}p/q+{1\over2}\rfloor$, when $p$ and $q$ are
+-positive. If |p| and |q| are both of the same scaled type |t|,
+-the ``type relation'' |make_frac(t,t)=fraction| is valid;
+-and it's also possible to use the subroutine ``backwards,'' using
+-the relation |make_frac(t,fraction)=t| between scaled types.
+-
+-If the result would have magnitude $2^{31}$ or more, |make_frac|
+-sets |arith_error:=true|. Most of \MP's internal computations have
+-been designed to avoid this sort of error.
+-
+-If this subroutine were programmed in assembly language on a typical
+-machine, we could simply compute |(@t$2^{28}$@>*p)div q|, since a
+-double-precision product can often be input to a fixed-point division
+-instruction. But when we are restricted to PASCAL arithmetic it
+-is necessary either to resort to multiple-precision maneuvering
+-or to use a simple but slow iteration. The multiple-precision technique
+-would be about three times faster than the code adopted here, but it
+-would be comparatively long and tricky, involving about sixteen
+-additional multiplications and divisions.
+-
+-This operation is part of \MP's ``inner loop''; indeed, it will
+-consume nearly 10\%! of the running time (exclusive of input and output)
+-if the code below is left unchanged. A machine-dependent recoding
+-will therefore make \MP\ run faster. The present implementation
+-is highly portable, but slow; it avoids multiplication and division
+-except in the initial stage. System wizards should be careful to
+-replace it with a routine that is guaranteed to produce identical
+-results in all cases.
+-@^system dependencies@>
+-
+-As noted below, a few more routines should also be replaced by machine-dependent
+-code, for efficiency. But when a procedure is not part of the ``inner loop,''
+-such changes aren't advisable; simplicity and robustness are
+-preferable to trickery, unless the cost is too high.

++
++    When \TeX\ appends new material to its main vlist in vertical mode, it uses a
++    method something like |vsplit| to decide where a page ends, except that the
++    calculations are done ``on line'' as new items come in. The main complication
++    in this process is that insertions must be put into their boxes and removed
++    from the vlist, in a more-or-less optimum manner.
++
++    We shall use the term ``current page'' for that part of the main vlist that
++    is being considered as a candidate for being broken off and sent to the
++    user's output routine. The current page starts at |vlink(page_head)|, and it
++    ends at |page_tail|. We have |page_head=page_tail| if this list is empty.
++
++    Utter chaos would reign if the user kept changing page specifications while a
++    page is being constructed, so the page builder keeps the pertinent
++    specifications frozen as soon as the page receives its first box or
++    insertion. The global variable |page_contents| is |empty| when the current
++    page contains only mark nodes and content-less whatsit nodes; it is
++    |inserts_only| if the page contains only insertion nodes in addition to marks
++    and whatsits. Glue nodes, kern nodes, and penalty nodes are discarded until a
++    box or rule node appears, at which time |page_contents| changes to
++    |box_there|. As soon as |page_contents| becomes non-|empty|, the current
++    |vsize| and |max_depth| are squirreled away into |page_goal| and
++    |page_max_depth|; the latter values will be used until the page has been
++    forwarded to the user's output routine. The \.{\\topskip} adjustment is made
++    when |page_contents| changes to |box_there|.
++
++    Although |page_goal| starts out equal to |vsize|, it is decreased by the
++    scaled natural height-plus-depth of the insertions considered so far, and by
++    the \.{\\skip} corrections for those insertions. Therefore it represents the
++    size into which the non-inserted material should fit, assuming that all
++    insertions in the current page have been made.
++
++    The global variables |best_page_break| and |least_page_cost| correspond
++    respectively to the local variables |best_place| and |least_cost| in the
++    |vert_break| routine that we have already studied; i.e., they record the
++    location and value of the best place currently known for breaking the current
++    page. The value of |page_goal| at the time of the best break is stored in
++    |best_size|.

++
++    The page builder has another data structure to keep track of insertions. This
++    is a list of four-word nodes, starting and ending at |page_ins_head|. That
++    is, the first element of the list is node |t$_1$=vlink(page_ins_head)|;
++    node $r_j$ is followed by |t$_{j+1}$=vlink(t$_j$)|; and if there are
++    |n| items we have |$_{n+1}$>=page_ins_head|. The |subtype| field of each
++    node in this list refers to an insertion number; for example, `\.{\\insert
++    250}' would correspond to a node whose |subtype| is |qi(250)| (the same as
++    the |subtype| field of the relevant |ins_node|). These |subtype| fields are
++    in increasing order, and |subtype(page_ins_head)=65535|, so |page_ins_head|
++    serves as a convenient sentinel at the end of the list. A record is present
++    for each insertion number that appears in the current page.
++
++    The |type| field in these nodes distinguishes two possibilities that might
++    occur as we look ahead before deciding on the optimum page break. If
++    |type(r)=inserting_node|, then |height(r)| contains the total of the
++    height-plus-depth dimensions of the box and all its inserts seen so far.
++    |type(r)=split_up_node|, then no more insertions will be made into this box,
++    because at least one previous insertion was too big to fit on the current
++    page; |broken_ptr(r)| points to the node where that insertion will be split,
++    if \TeX\ decides to split it, |broken_ins(r)| points to the insertion node
++    that was tentatively split, and |height(r)| includes also the natural height
++    plus depth of the part that would be split off.
++
++    In both cases, |last_ins_ptr(r)| points to the last |ins_node| encountered
++    for box |qo(subtype(r))| that would be at least partially inserted on the
++    next page; and |best_ins_ptr(r)| points to the last such |ins_node| that
++    should actually be inserted, to get the page with minimum badness among all
++    page breaks considered so far. We have |best_ins_ptr(r)=null| if and only if
++    no insertion for this box should be made to produce this optimum page.
++
++    Pages are built by appending nodes to the current list in \TeX's vertical
++    mode, which is at the outermost level of the semantic nest. This vlist is
++    split into two parts; the ``current page'' that we have been talking so much
++    about already, and the ``contribution list'' that receives new nodes as they
++    are created. The current page contains everything that the page builder has
++    accounted for in its data structures, as described above, while the
++    contribution list contains other things that have been generated by other
++    parts of \TeX\ but have not yet been seen by the page builder. The
++    contribution list starts at |vlink(contrib_head)|, and it ends at the current
++    node in \TeX's vertical mode.
++

++                            |n| over 1000.) Now we will choose the best way to
++                            break the vlist of the insertion, using the same

+-@ When \TeX\ appends new material to its main vlist in vertical mode, it uses
+-a method something like |vsplit| to decide where a page ends, except that
+-the calculations are done ``on line'' as new items come in.
+-The main complication in this process is that insertions must be put
+-into their boxes and removed from the vlist, in a more-or-less optimum manner.
+-
+-We shall use the term ``current page'' for that part of the main vlist that
+-is being considered as a candidate for being broken off and sent to the
+-user's output routine. The current page starts at |vlink(page_head)|, and
+-it ends at |page_tail|.  We have |page_head=page_tail| if this list is empty.
+-@^current page@>
+-
+-Utter chaos would reign if the user kept changing page specifications
+-while a page is being constructed, so the page builder keeps the pertinent
+-specifications frozen as soon as the page receives its first box or
+-insertion.  The global variable |page_contents| is |empty| when the
+-current page contains only mark nodes and content-less whatsit nodes; it
+-is |inserts_only| if the page contains only insertion nodes in addition to
+-marks and whatsits.  Glue nodes, kern nodes, and penalty nodes are
+-discarded until a box or rule node appears, at which time |page_contents|
+-changes to |box_there|.  As soon as |page_contents| becomes non-|empty|,
+-the current |vsize| and |max_depth| are squirreled away into |page_goal|
+-and |page_max_depth|; the latter values will be used until the page has
+-been forwarded to the user's output routine. The \.{\\topskip} adjustment
+-is made when |page_contents| changes to |box_there|.
+-
+-Although |page_goal| starts out equal to |vsize|, it is decreased by the
+-scaled natural height-plus-depth of the insertions considered so far, and by
+-the \.{\\skip} corrections for those insertions. Therefore it represents
+-the size into which the non-inserted material should fit, assuming that
+-all insertions in the current page have been made.
+-
+-The global variables |best_page_break| and |least_page_cost| correspond
+-respectively to the local variables |best_place| and |least_cost| in the
+-|vert_break| routine that we have already studied; i.e., they record the
+-location and value of the best place currently known for breaking the
+-current page. The value of |page_goal| at the time of the best break is
+-stored in |best_size|.
+-
+-@c
+-halfword page_tail;             /* the final node on the current page */
+-int page_contents;              /* what is on the current page so far? */
+-scaled page_max_depth;          /* maximum box depth on page being built */
+-halfword best_page_break;       /* break here to get the best page known so far */
+-int least_page_cost;            /* the score for this currently best page */
+-scaled best_size;               /* its |page_goal| */
+-
+-@ The page builder has another data structure to keep track of insertions.
+-This is a list of four-word nodes, starting and ending at |page_ins_head|.
+-That is, the first element of the list is node |r@t$_1$@>=vlink(page_ins_head)|;
+-node $r_j$ is followed by |r@t$_{j+1}$@>=vlink(r@t$_j$@>)|; and if there are
+-|n| items we have |r@t$_{n+1}$@>=page_ins_head|. The |subtype| field of
+-each node in this list refers to an insertion number; for example, `\.{\\insert
+-250}' would correspond to a node whose |subtype| is |qi(250)|
+-(the same as the |subtype| field of the relevant |ins_node|). These |subtype|
+-fields are in increasing order, and |subtype(page_ins_head)=65535|, so
+-|page_ins_head| serves as a convenient sentinel
+-at the end of the list. A record is present for each insertion number that
+-appears in the current page.
+-
+-The |type| field in these nodes distinguishes two possibilities that
+-might occur as we look ahead before deciding on the optimum page break.
+-If |type(r)=inserting_node|, then |height(r)| contains the total of the
+-height-plus-depth dimensions of the box and all its inserts seen so far.
+- |type(r)=split_up_node|, then no more insertions will be made into this box,
+-because at least one previous insertion was too big to fit on the current
+-page; |broken_ptr(r)| points to the node where that insertion will be
+-split, if \TeX\ decides to split it, |broken_ins(r)| points to the
+-insertion node that was tentatively split, and |height(r)| includes also the
+-natural height plus depth of the part that would be split off.
+-
+-In both cases, |last_ins_ptr(r)| points to the last |ins_node|
+-encountered for box |qo(subtype(r))| that would be at least partially
+-inserted on the next page; and |best_ins_ptr(r)| points to the last
+-such |ins_node| that should actually be inserted, to get the page with
+-minimum badness among all page breaks considered so far. We have
+-|best_ins_ptr(r)=null| if and only if no insertion for this box should
+-be made to produce this optimum page.
+-
+-@ Pages are built by appending nodes to the current list in \TeX's
+-vertical mode, which is at the outermost level of the semantic nest. This
+-vlist is split into two parts; the ``current page'' that we have been
+-talking so much about already, and the ``contribution list'' that receives
+-new nodes as they are created.  The current page contains everything that
+-the page builder has accounted for in its data structures, as described
+-above, while the contribution list contains other things that have been
+-generated by other parts of \TeX\ but have not yet been
+-seen by the page builder.
+-The contribution list starts at |vlink(contrib_head)|, and it ends at the
+-current node in \TeX's vertical mode.
+-
+-When \TeX\ has appended new material in vertical mode, it calls the procedure
+-|build_page|, which tries to catch up by moving nodes from the contribution
+-list to the current page. This procedure will succeed in its goal of
+-emptying the contribution list, unless a page break is discovered, i.e.,
+-unless the current page has grown to the point where the optimum next
+-page break has been determined. In the latter case, the nodes after the
+-optimum break will go back onto the contribution list, and control will
+-effectively pass to the user's output routine.
+-
+-We make |type(page_head)=glue_node|, so that an initial glue node on
+-the current page will not be considered a valid breakpoint.
+-
+-@c
+-void initialize_buildpage(void)
+-{
+-    subtype(page_ins_head) = 65535;
+-    type(page_ins_head) = split_up_node;
+-    vlink(page_ins_head) = page_ins_head;
+-
+-    type(page_head) = glue_node;
+-    subtype(page_head) = normal;
+-}
+-
+-
+-@ An array |page_so_far| records the heights and depths of everything
+-on the current page. This array contains six |scaled| numbers, like the
+-similar arrays already considered in |line_break| and |vert_break|; and it
+-also contains |page_goal| and |page_depth|, since these values are
+-all accessible to the user via |set_page_dimen| commands. The

+-corrections are not, since they have been subtracted from |page_goal|.
+-
+-The variable |page_depth| records the depth of the current page; it has been
+-adjusted so that it is at most |page_max_depth|. The variable
+-|last_glue| points to the glue specification of the most recent node
+-contributed from the contribution list, if this was a glue node; otherwise
+-|last_glue=max_halfword|. (If the contribution list is nonempty,
+-however, the value of |last_glue| is not necessarily accurate.)
+-The variables |last_penalty|, |last_kern|, and |last_node_type|
+-are similar.  And
+-finally, |insert_penalties| holds the sum of the penalties associated with
+-all split and floating insertions.

+-@ Let's pause a moment now and try to look at the Big Picture.
+-The \TeX\ program consists of three main parts: syntactic routines,
+-semantic routines, and output routines. The chief purpose of the
+-syntactic routines is to deliver the user's input to the semantic routines,
+-one token at a time. The semantic routines act as an interpreter
+-responding to these tokens, which may be regarded as commands. And the
+-output routines are periodically called on to convert box-and-glue
+-lists into a compact set of instructions that will be sent
+-to a typesetter. We have discussed the basic data structures and utility
+-routines of \TeX, so we are good and ready to plunge into the real activity by
+-considering the syntactic routines.
+-
+-Our current goal is to come to grips with the |get_next| procedure,
+-which is the keystone of \TeX's input mechanism. Each call of |get_next|
+-sets the value of three variables |cur_cmd|, |cur_chr|, and |cur_cs|,
+-representing the next input token.
+-$$\vbox{\halign{#\hfil\cr
+-  \hbox{|cur_cmd| denotes a command code from the long list of codes
+-   given above;}\cr
+-  \hbox{|cur_chr| denotes a character code or other modifier of the command
+-   code;}\cr
+-  \hbox{|cur_cs| is the |eqtb| location of the current control sequence,}\cr
+-  \hbox{\qquad if the current token was a control sequence,
+-   otherwise it's zero.}\cr}}$$
+-Underlying this external behavior of |get_next| is all the machinery
+-necessary to convert from character files to tokens. At a given time we
+-may be only partially finished with the reading of several files (for
+-which \.{\\input} was specified), and partially finished with the expansion
+-of some user-defined macros and/or some macro parameters, and partially
+-finished with the generation of some text in a template for \.{\\halign},
+-and so on. When reading a character file, special characters must be
+-classified as math delimiters, etc.; comments and extra blank spaces must
+-be removed, paragraphs must be recognized, and control sequences must be
+-found in the hash table. Furthermore there are occasions in which the
+-scanning routines have looked ahead for a word like `\.{plus}' but only
+-part of that word was found, hence a few characters must be put back
+-into the input and scanned again.
+-
+-To handle these situations, which might all be present simultaneously,
+-\TeX\ uses various stacks that hold information about the incomplete
+-activities, and there is a finite state control for each level of the
+-input mechanism. These stacks record the current state of an implicitly
+-recursive process, but the |get_next| procedure is not recursive.
+-Therefore it will not be difficult to translate these algorithms into
+-low-level languages that do not support recursion.

+-@ TODO: we need to use a formatted normal_error in:
+-
+-hyphen.w
+-luafflib.c
+-
+-@ @c
+-#include "ptexlib.h"
+-#define edit_var "TEXEDIT"
+-
+-@ When something anomalous is detected, \TeX\ typically does something like this:
+-$$\vbox{\halign{#\hfil\cr
+-|print_err("Something anomalous has been detected");|\cr
+-|help3("This is the first line of my offer to help.")|\cr
+-|("This is the second line. I'm trying to")|\cr
+-|("explain the best way for you to proceed.");|\cr
+-|error;|\cr}}$$
+-A two-line help message would be given using |help2|, etc.; these informal
+-helps should use simple vocabulary that complements the words used in the
+-official error message that was printed. (Outside the U.S.A., the help
+-messages should preferably be translated into the local vernacular. Each
+-line of help is at most 60 characters long, in the present implementation,
+-so that |max_print_line| will not be exceeded.)
+-
+-The |print_err| procedure supplies a `\.!' before the official message,
+-and makes sure that the terminal is awake if a stop is going to occur.
+-The |error| procedure supplies a `\..' after the official message, then it
+-shows the location of the error; and if |interaction=error_stop_mode|,
+-it also enters into a dialog with the user, during which time the help
+-message may be printed.

+-Sometimes, recursive calls to the following |expand| routine may
+-cause exhaustion of the run-time calling stack, resulting in
+-forced execution stops by the operating system. To diminish the chance
+-of this happening, a counter is used to keep track of the recursion
+-depth, in conjunction with a constant called |expand_depth|.
+-
+-Note that this does not catch all possible infinite recursion loops,
+-just the ones that exhaust the application calling stack. The
+-actual maximum value of |expand_depth| is outside of our control, but
+-the initial setting of |100| should be enough to prevent problems.

+-
+-@ The |expand| subroutine is used when |cur_cmd>max_command|. It removes a
+-``call'' or a conditional or one of the other special operations just
+-listed.  It follows that |expand| might invoke itself recursively. In all
+-cases, |expand| destroys the current token, but it sets things up so that
+-the next |get_next| will deliver the appropriate next token. The value of
+-|cur_tok| need not be known when |expand| is called.
+-
+-Since several of the basic scanning routines communicate via global variables,
+-their values are saved as local variables of |expand| so that
+-recursive calls don't invalidate them.

+-arrays by symbolic macros |top_mark|, etc. The value of |top_mark(x)|, etc.

+-appears in the token list whose reference count is in location |cur_chr|
+-of |mem|.
+-
+-The global variable |long_state| will be set to |call| or to |long_call|,
+-depending on whether or not the control sequence disallows \.{\\par}
+-in its parameters. The |get_next| routine will set |long_state| to

+-control sequence occurs in the midst of an argument.

+-an auxiliary stack called |pstack| while they are being scanned, since
+-the |param_stack| may be losing entries during the matching process.
+-(Note that |param_stack| can't be gaining entries, since |macro_call| is

+-next.
+-
+-The global variable |cur_cs| contains the |eqtb| address of the control sequence
+-being expanded, when |macro_call| begins. If this control sequence has not been
+-declared \.{\\long}, i.e., if its command code in the |eq_type| field is

+-               Incidentally, it is possible for \.{\\par} tokens to sneak in to certain

++
++    The program above includes a bunch of ``hooks'' that allow further
++    capabilities to be added without upsetting \TeX's basic structure. Most of
++    these hooks are concerned with ``whatsit'' nodes, which are intended to be
++    used for special purposes; whenever a new extension to \TeX\ involves a new
++    kind of whatsit node, a corresponding change needs to be made to the routines
++    below that deal with such nodes, but it will usually be unnecessary to make
++    many changes to the other parts of this program.
++
++    In order to demonstrate how extensions can be made, we shall treat
++    `\.{\\write}', `\.{\\openout}', `\.{\\closeout}', `\.{\\immediate}', and
++    `\.{\\special}' as if they were extensions. These commands are actually
++    primitives of \TeX, and they should appear in all implementations of the
++    system; but let's try to imagine that they aren't. Then the program below
++    illustrates how a person could add them.
++
++    Sometimes, of course, an extension will require changes to \TeX\ itself; no
++    system of hooks could be complete enough for all conceivable extensions. The
++    features associated with `\.{\\write}' are almost all confined to the
++    following paragraphs, but there are small parts of the |print_ln| and
++    |print_char| procedures that were introduced specifically to \.{\\write}
++    characters. Furthermore one of the token lists recognized by the scanner is a
++    |write_text|; and there are a few other miscellaneous places where we have
++    already provided for some aspect of \.{\\write}. The goal of a \TeX\ extender
++    should be to minimize alterations to the standard parts of the program, and
++    to avoid them completely if possible. He or she should also be quite sure
++    that there's no easy way to accomplish the desired goals with the standard
++    features that \TeX\ already has. ``Think thrice before extending,'' because
++    that may save a lot of work, and it will also keep incompatible extensions of
++    \TeX\ from proliferating.
++
++    First let's consider the format of whatsit nodes that are used to represent
++    the data associated with \.{\\write} and its relatives. Recall that a whatsit
++    has |type=whatsit_node|, and the |subtype| is supposed to distinguish
++    different kinds of whatsits. Each node occupies two or more words; the exact
++    number is immaterial, as long as it is readily determined from the |subtype|
++    or other data.
++
++    We shall introduce five |subtype| values here, corresponding to the control
++    sequences \.{\\openout}, \.{\\write}, \.{\\closeout}, and \.{\\special}. The
++    second word of I/O whatsits has a |write_stream| field that identifies the
++    write-stream number (0 to 15, or 16 for out-of-range and positive, or 17 for
++    out-of-range and negative). In the case of \.{\\write} and \.{\\special},
++    there is also a field that points to the reference count of a token list that
++    should be sent. In the case of \.{\\openout}, we need three words and three
++    auxiliary subfields to hold the string numbers for name, area, and extension.
++
++    Extensions might introduce new command codes; but it's best to use
++    |extension| with a modifier, whenever possible, so that |main_control| stays
++    the same.
++
++    The sixteen possible \.{\\write} streams are represented by the |write_file|
++    array. The |j|th file is open if and only if |write_open[j]=true|. The last
++    two streams are special; |write_open[16]| represents a stream number greater
++    than 15, while |write_open[17]| represents a negative stream number, and both
++    of these variables are always |false|.

++    This section is devoted to the {\sl Synchronize \TeX nology} - or simply {\sl
++    Sync\TeX} - used to synchronize between input and output. This section
++    explains how synchronization basics are implemented. Before we enter into
++    more technical details, let us recall in a few words what is synchronization.
++
++    \TeX\ typesetting system clearly separates the input and the output material,
++    and synchronization will provide a new link between both that can help text
++    editors and viewers to work together. More precisely, forwards
++    synchronization is the ability, given a location in the input source file, to
++    find what is the corresponding place in the output. Backwards synchronization
++    just performs the opposite: given a location in the output, retrieve the
++    corresponding material in the input source file.
++
++    For better code management and maintainance, we adopt a naming convention.
++    Throughout this program, code related to the {\sl Synchronize \TeX nology} is
++    tagged with the ``{\sl synctex}'' key word. Any code extract where {\sl
++    Sync\TeX} plays its part, either explicitly or implicitly, (should) contain
++    the string ``{\sl synctex}''. This naming convention also holds for external
++    files. Moreover, all the code related to {\sl Sync\TeX} is gathered in this
++    section, except the definitions.
++
++    Enabling synchronization should be performed from the command line,
++    |synctexoption| is used for that purpose. This global integer variable is
++    declared here but it is not used here. This is just a placeholder where the
++    command line controller will put the {\sl Sync\TeX} related options, and the
++    {\sl Sync\TeX} controller will read them.
++
++*/
++
++int synctexoption;
++
++/*tex
++
++    A convenient primitive is provided: \.{\\synctex=1} in the input source file
++    enables synchronization whereas \.{\\synctex=0} disables it. Its memory
++    address is |synctex_code|. It is initialized by the {\sl Sync\TeX} controller
++    to the command-line option if given. The controller may filter some reserved
++    bits.
++
++    In order to give the {\sl Sync\TeX} controller read and write access to the
++    contents of the \.{\\synctex} primitive, we declare |synctexoffset|, such
++    that |mem[synctexoffset]| and \.{\\synctex} correspond to the same memory
++    storage. |synctexoffset| is initialized to the correct value when quite
++    everything is initialized.
++
++*/
++
++/*tex Holds the true value of |synctex_code|: */
++
++int synctexoffset;
++
++/*tex
++
++    Synchronization is achieved with the help of an auxiliary file named `\.{{\sl
++    jobname}.synctex}' ({\sl jobname} is the contents of the \.{\\jobname}
++    macro), where a {\sl Sync\TeX} controller implemented in the external
++    |synctex.c| file will store geometrical information. This {\sl Sync\TeX}
++    controller will take care of every technical details concerning the {\sl
++    Sync\TeX} file, we will only focus on the messages the controller will
++    receive from the \TeX\ program.
++
++    The most accurate synchronization information should allow to map any
++    character of the input source file to the corresponding location in the
++    output, if relevant. Ideally, the synchronization information of the input
++    material consists of the file name, the line and column numbers of every
++    character. The synchronization information in the output is simply the page
++    number and either point coordinates, or box dimensions and position. The
++    problem is that the mapping between these informations is only known at ship
++    out time, which means that we must keep track of the input synchronization
++    information until the pages ship out.
++
++    As \TeX\ only knows about file names and line numbers, but forgets the column
++    numbers, we only consider a restricted input synchronization information
++    called {\sl Sync\TeX\ information}. It consists of a unique file name
++    identifier, the {\sl Sync\TeX\ file tag}, and the line number.
++
++    Keeping track of such information, should be different whether characters or
++    nodes are involved. Actually, only certain nodes are involved in {\sl
++    Sync\TeX}, we call them {\sl synchronized nodes}. Synchronized nodes store
++    the {\sl Sync\TeX} information in their last two words: the first one
++    contains a {\sl Sync\TeX\ file tag} uniquely identifying the input file, and
++    the second one contains the current line number, as returned by the
++    \.{\\inputlineno} primitive. The |synctex_field_size| macro contains the
++    necessary size to store the {\sl Sync\TeX} information in a node.
++
++    When declaring the size of a new node, it is recommanded to use the following
++    convention: if the node is synchronized, use a definition similar to
++    |my_synchronized_node_size|={\sl xxx}+|synctex_field_size|. Moreover, one
++    should expect that the {\sl Sync\TeX} information is always stored in the
++    last two words of a synchronized node.
++
++    By default, every node with a sufficiently big size is initialized at
++    creation time in the |get_node| routine with the current {\sl Sync\TeX}
++    information, whether or not the node is synchronized. One purpose is to set
++    this information very early in order to minimize code dependencies, including
++    forthcoming extensions. Another purpose is to avoid the assumption that every
++    node type has a dedicated getter, where initialization should take place.
++    Actually, it appears that some nodes are created using directly the
++    |get_node| routine and not the dedicated constructor. And finally,
++    initializing the node at only one place is less error prone.
++
++    Instead of storing the input file name, it is better to store just an
++    identifier. Each time \TeX\ opens a new file, it notifies the {\sl Sync\TeX}
++    controller with a |synctex_start_input| message. This controller will create
++    a new {\sl Sync\TeX} file tag and will update the current input state record
++    accordingly. If the input comes from the terminal or a pseudo file, the
++    |synctex_tag| is set to 0. It results in automatically disabling
++    synchronization for material input from the terminal or pseudo files.
++
++    Synchronized nodes are boxes, math, kern and glue nodes. Other nodes should
++    be synchronized too, in particular math noads. \TeX\ assumes that math, kern
++    and glue nodes have the same size, this is why both are synchronized. {\sl In
++    fine}, only horizontal lists are really used in {\sl Sync\TeX}, but all box
++    nodes are considered the same with respect to synchronization, because a box
++    node type is allowed to change at execution time.
++
++    {\em Nota Bene:} The {\sl Sync\TeX} code is very close to the memory model.
++    It is not connected to any other part of the code, except for memory
++    management. It is possible to neutralize the {\sl Sync\TeX} code rather
++    simply. The first step is to define a null |synctex_field_size|. The second
++    step is to comment out the code in ``Initialize bigger nodes...'' and every
++    ``Copy ... {\sl Sync\TeX} information''. The last step will be to comment out
++    the |synctex_tag_field| related code in the definition of |synctex_tag| and
++    the various ``Prepare ... {\sl Sync\TeX} information''. Then all the
++    remaining code should be just harmless. The resulting program would behave
++    exactly the same as if absolutely no {\sl Sync\TeX} related code was there,
++    including memory management. Of course, all this assumes that {\sl Sync\TeX}
++    is turned off from the command line.
++
++    Here are extra variables for Web2c. (This numbering of the system-dependent
++    section allows easy integration of Web2c and e-\TeX, etc.)

+-@ The program above includes a bunch of ``hooks'' that allow further
+-capabilities to be added without upsetting \TeX's basic structure.
+-Most of these hooks are concerned with ``whatsit'' nodes, which are
+-intended to be used for special purposes; whenever a new extension to
+-\TeX\ involves a new kind of whatsit node, a corresponding change needs
+-to be made to the routines below that deal with such nodes,
+-but it will usually be unnecessary to make many changes to the
+-other parts of this program.
+-
+-In order to demonstrate how extensions can be made, we shall treat
+-`\.{\\write}', `\.{\\openout}', `\.{\\closeout}', `\.{\\immediate}',
+-and `\.{\\special}' as if they were extensions.
+-These commands are actually primitives of \TeX, and they should
+-appear in all implementations of the system; but let's try to imagine
+-that they aren't. Then the program below illustrates how a person
+-could add them.
+-
+-Sometimes, of course, an extension will require changes to \TeX\ itself;
+-no system of hooks could be complete enough for all conceivable extensions.
+-The features associated with `\.{\\write}' are almost all confined to the
+-following paragraphs, but there are small parts of the |print_ln| and
+-|print_char| procedures that were introduced specifically to \.{\\write}
+-characters. Furthermore one of the token lists recognized by the scanner
+-is a |write_text|; and there are a few other miscellaneous places where we
+-have already provided for some aspect of \.{\\write}.  The goal of a \TeX\
+-extender should be to minimize alterations to the standard parts of the
+-program, and to avoid them completely if possible. He or she should also
+-be quite sure that there's no easy way to accomplish the desired goals
+-with the standard features that \TeX\ already has. ``Think thrice before
+-extending,'' because that may save a lot of work, and it will also keep
+-incompatible extensions of \TeX\ from proliferating.
+-@^system dependencies@>
+-@^extensions to \TeX@>
+-
+-First let's consider the format of whatsit nodes that are used to represent
+-the data associated with \.{\\write} and its relatives. Recall that a whatsit
+-has |type=whatsit_node|, and the |subtype| is supposed to distinguish
+-different kinds of whatsits. Each node occupies two or more words; the
+-exact number is immaterial, as long as it is readily determined from the
+-|subtype| or other data.
+-
+-We shall introduce five |subtype| values here, corresponding to the
+-control sequences \.{\\openout}, \.{\\write}, \.{\\closeout}, and \.{\\special}.
+-The second word of I/O whatsits has a |write_stream| field
+-that identifies the write-stream number (0 to 15, or 16 for out-of-range and
+-positive, or 17 for out-of-range and negative).
+-In the case of \.{\\write} and \.{\\special}, there is also a field that
+-points to the reference count of a token list that should be sent. In the
+-case of \.{\\openout}, we need three words and three auxiliary subfields
+-to hold the string numbers for name, area, and extension.
+-
+-@ Extensions might introduce new command codes; but it's best to use
+-|extension| with a modifier, whenever possible, so that |main_control|
+-stays the same.
+-
+-@ The sixteen possible \.{\\write} streams are represented by the |write_file|
+-array. The |j|th file is open if and only if |write_open[j]=true|. The last
+-two streams are special; |write_open[16]| represents a stream number
+-greater than 15, while |write_open[17]| represents a negative stream number,
+-and both of these variables are always |false|.

+-@ This section is devoted to the {\sl Synchronize \TeX nology}
+-- or simply {\sl Sync\TeX} - used to synchronize between input and output.
+-This section explains how synchronization basics are implemented.
+-Before we enter into more technical details,
+-let us recall in a few words what is synchronization.
+-
+-\TeX\ typesetting system clearly separates the input and the output material,
+-and synchronization will provide a new link between both that can help
+-text editors and viewers to work together.
+-More precisely, forwards synchronization is the ability,
+-given a location in the input source file,
+-to find what is the corresponding place in the output.
+-Backwards synchronization just performs the opposite:
+-given a location in the output,
+-retrieve the corresponding material in the input source file.
+-
+-For better code management and maintainance, we adopt a naming convention.
+-Throughout this program, code related to the {\sl Synchronize \TeX nology} is tagged
+-with the ``{\sl synctex}'' key word. Any code extract where {\sl Sync\TeX} plays
+-its part, either explicitly or implicitly, (should) contain the string ``{\sl synctex}''.
+-This naming convention also holds for external files.
+-Moreover, all the code related to {\sl Sync\TeX} is gathered in this section,
+-except the definitions.
+-
+-Enabling synchronization should be performed from the command line,
+-|synctexoption| is used for that purpose.
+-This global integer variable is declared here but it is not used here.
+-This is just a placeholder where the command line controller will put
+-the {\sl Sync\TeX} related options, and the {\sl Sync\TeX} controller will read them.
+-
+-@c
+-int synctexoption;
+-
+-@ A convenient primitive is provided:
+-\.{\\synctex=1} in the input source file enables synchronization whereas
+-\.{\\synctex=0} disables it.
+-Its memory address is |synctex_code|.
+-It is initialized by the {\sl Sync\TeX} controller to the command-line option if given.
+-The controller may filter some reserved bits.
+-
+-In order to give the {\sl Sync\TeX} controller read and write access to
+-the contents of the \.{\\synctex} primitive, we declare |synctexoffset|,
+-such that |mem[synctexoffset]| and \.{\\synctex} correspond to
+-the same memory storage. |synctexoffset| is initialized to
+-the correct value when quite everything is initialized.
+-
+-@c
+-int synctexoffset;              /* holds the true value of |synctex_code| */
+-
+-@ Synchronization is achieved with the help of an auxiliary file named
+-`\.{{\sl jobname}.synctex}' ({\sl jobname} is the contents of the
+-\.{\\jobname} macro), where a {\sl Sync\TeX} controller implemented
+-in the external |synctex.c| file will store geometrical information.
+-This {\sl Sync\TeX} controller will take care of every technical details
+-concerning the {\sl Sync\TeX} file, we will only focus on the messages
+-the controller will receive from the \TeX\ program.
+-
+-The most accurate synchronization information should allow to map
+-any character of the input source file to the corresponding location
+-in the output, if relevant.
+-Ideally, the synchronization information of the input material consists of
+-the file name, the line and column numbers of every character.
+-The synchronization information in the output is simply the page number and
+-either point coordinates, or box dimensions and position.
+-The problem is that the mapping between these informations is only known at
+-ship out time, which means that we must keep track of the input
+-synchronization information until the pages ship out.
+-
+-As \TeX\ only knows about file names and line numbers,
+-but forgets the column numbers, we only consider a
+-restricted input synchronization information called {\sl Sync\TeX\ information}.
+-It consists of a unique file name identifier, the {\sl Sync\TeX\ file tag},
+-and the line number.
+-
+-Keeping track of such information,
+-should be different whether characters or nodes are involved.
+-Actually, only certain nodes are involved in {\sl Sync\TeX},
+-we call them {\sl synchronized nodes}.
+-Synchronized nodes store the {\sl Sync\TeX} information in their last two words:
+-the first one contains a {\sl Sync\TeX\ file tag} uniquely identifying
+-the input file, and the second one contains the current line number,
+-as returned by the \.{\\inputlineno} primitive.
+-The |synctex_field_size| macro contains the necessary size to store
+-the {\sl Sync\TeX} information in a node.
+-
+-When declaring the size of a new node, it is recommanded to use the following
+-convention: if the node is synchronized, use a definition similar to
+-|my_synchronized_node_size|={\sl xxx}+|synctex_field_size|.
+-Moreover, one should expect that the {\sl Sync\TeX} information is always stored
+-in the last two words of a synchronized node.
+-
+-By default, every node with a sufficiently big size is initialized
+-at creation time in the |get_node| routine with the current
+-{\sl Sync\TeX} information, whether or not the node is synchronized.
+-One purpose is to set this information very early in order to minimize code
+-dependencies, including forthcoming extensions.
+-Another purpose is to avoid the assumption that every node type has a dedicated getter,
+-where initialization should take place. Actually, it appears that some nodes are created
+-using directly the |get_node| routine and not the dedicated constructor.
+-And finally, initializing the node at only one place is less error prone.
+-
+-Instead of storing the input file name, it is better to store just an identifier.
+-Each time \TeX\ opens a new file, it notifies the {\sl Sync\TeX} controller with
+-a |synctex_start_input| message.
+-This controller will create a new {\sl Sync\TeX} file tag and
+-will update the current input state record accordingly.
+-If the input comes from the terminal or a pseudo file, the |synctex_tag| is set to 0.
+-It results in automatically disabling synchronization for material
+-input from the terminal or pseudo files.
+-
+-Synchronized nodes are boxes, math, kern and glue nodes.
+-Other nodes should be synchronized too, in particular math noads.
+-\TeX\ assumes that math, kern and glue nodes have the same size,
+-this is why both are synchronized.
+-{\sl In fine}, only horizontal lists are really used in {\sl Sync\TeX},
+-but all box nodes are considered the same with respect to synchronization,
+-because a box node type is allowed to change at execution time.
+-
+-{\sl Nota Bene:}
+-The {\sl Sync\TeX} code is very close to the memory model.
+-It is not connected to any other part of the code,
+-except for memory management. It is possible to neutralize the {\sl Sync\TeX} code
+-rather simply. The first step is to define a null |synctex_field_size|.
+-The second step is to comment out the code in ``Initialize bigger nodes...'' and every
+-``Copy ... {\sl Sync\TeX} information''.
+-The last step will be to comment out the |synctex_tag_field| related code in the
+-definition of |synctex_tag| and the various ``Prepare ... {\sl Sync\TeX} information''.
+-Then all the remaining code should be just harmless.
+-The resulting program would behave exactly the same as if absolutely no {\sl Sync\TeX}
+-related code was there, including memory management.
+-Of course, all this assumes that {\sl Sync\TeX} is turned off from the command line.

++
++    We come now to what is probably the most interesting algorithm of \TeX: the
++    mechanism for choosing the ``best possible'' breakpoints that yield the
++    individual lines of a paragraph. \TeX's line-breaking algorithm takes a given
++    horizontal list and converts it to a sequence of boxes that are appended to
++    the current vertical list. In the course of doing this, it creates a special
++    data structure containing three kinds of records that are not used elsewhere
++    in \TeX. Such nodes are created while a paragraph is being processed, and
++    they are destroyed afterwards; thus, the other parts of \TeX\ do not need to
++    know anything about how line-breaking is done.
++
++    The method used here is based on an approach devised by Michael F. Plass and
++    the author in 1977, subsequently generalized and improved by the same two
++    people in 1980. A detailed discussion appears in {\sl SOFTWARE---Practice
++    \AM\ Experience \bf11} (1981), 1119--1184, where it is shown that the
++    line-breaking problem can be regarded as a special case of the problem of
++    computing the shortest path in an acyclic network. The cited paper includes
++    numerous examples and describes the history of line breaking as it has been
++    practiced by printers through the ages. The present implementation adds two
++    new ideas to the algorithm of 1980: Memory space requirements are
++    considerably reduced by using smaller records for inactive nodes than for
++    active ones, and arithmetic overflow is avoided by using ``delta distances''
++    instead of keeping track of the total distance from the beginning of the
++    paragraph to the current point.
++
++    The |line_break| procedure should be invoked only in horizontal mode; it
++    leaves that mode and places its output into the current vlist of the
++    enclosing vertical mode (or internal vertical mode). There is one explicit
++    parameter: |d| is true for partial paragraphs preceding display math mode; in
++    this case the amount of additional penalty inserted before the final line is
++    |display_widow_penalty| instead of |widow_penalty|.
++
++    There are also a number of implicit parameters: The hlist to be broken starts
++    at |vlink(head)|, and it is nonempty. The value of |prev_graf| in the
++    enclosing semantic level tells where the paragraph should begin in the
++    sequence of line numbers, in case hanging indentation or \.{\\parshape} are
++    in use; |prev_graf| is zero unless this paragraph is being continued after a
++    displayed formula. Other implicit parameters, such as the |par_shape_ptr| and
++    various penalties to use for hyphenation, etc., appear in |eqtb|.
++
++    After |line_break| has acted, it will have updated the current vlist and the
++    value of |prev_graf|. Furthermore, the global variable |just_box| will point
++    to the final box created by |line_break|, so that the width of this line can
++    be ascertained when it is necessary to decide whether to use
++    |above_display_skip| or |above_display_short_skip| before a displayed
++    formula.

++
++    In it's complete form, |line_break| is a rather lengthy procedure---sort of a
++    small world unto itself---we must build it up little by little. Below you see
++    only the general outline.
++
++    The main task performed here is to move the list from |head| to |temp_head|
++    and go into the enclosing semantic level. We also append the
++    \.{\\parfillskip} glue to the end of the paragraph, removing a space (or
++    other glue node) if it was there, since spaces usually precede blank lines
++    and instances of `\.{\$\$}'. The |par_fill_skip| is preceded by an infinite
++    penalty, so it will never be considered as a potential breakpoint.
++
++    That code assumes that a |glue_node| and a |penalty_node| occupy the same
++    number of |mem|~words.
++
++    Most other processing is delegated to external functions.

++    The algorithm essentially determines the best possible way to achieve each

++    questions like, ``What is the best way to break the opening part of the
++    paragraph so that the fourth line is a tight line ending at such-and-such a
++    place?'' However, the fact that all lines are to be the same length after a
++    certain point makes it possible to regard all sufficiently large line numbers
++    as equivalent, when the looseness parameter is zero, and this makes it
++    possible for the algorithm to save space and time.
++
++    An ``active node'' and a ``passive node'' are created in |mem| for each

++    The active list also contains ``delta'' nodes that help the algorithm compute
++    the badness of individual lines. Such nodes appear only between two active
++    nodes, and they have |type=delta_node|. If |p| and |r| are active nodes and
++    if |q| is a delta node between them, so that |vlink(p)=q| and |vlink(q)=r|,
++    then |q| tells the space difference between lines in the horizontal list that
++    start after breakpoint |p| and lines that start after breakpoint |r|. In
++    other words, if we know the length of the line that starts after |p| and ends
++    at our current position, then the corresponding length of the line that
++    starts after |r| is obtained by adding the amounts in node~|q|. A delta node
++    contains seven scaled numbers, since it must record the net change in glue
++    stretchability with respect to all orders of infinity. The natural width
++    difference appears in |mem[q+1].sc|; the stretch differences in units of pt,
++    sfi, fil, fill, and filll appear in |mem[q+2..q+6].sc|; and the shrink
++    difference appears in |mem[q+7].sc|. The |subtype| field of a delta node is
++    not used.
++
++    Actually, we have two more fields that are used by |pdftex|.
++
++    As the algorithm runs, it maintains a set of seven delta-like registers for
++    the length of the line following the first active breakpoint to the current
++    position in the given hlist. When it makes a pass through the active list, it
++    also maintains a similar set of seven registers for the length following the
++    active breakpoint of current interest. A third set holds the length of an
++    empty line (namely, the sum of \.{\\leftskip} and \.{\\rightskip}); and a
++    fourth set is used to create new delta nodes.
++
++    When we pass a delta node we want to do operations like:
++
++    \starttyping
++    for k := 1 to 7 do
++        cur_active_width[k] := cur_active_width[k] + mem[q+k].sc|};
++    \stoptyping
++
++    and we want to do this without the overhead of |for| loops. The |do_all_six|
++    macro makes such six-tuples convenient.

++
++    Let's state the principles of the delta nodes more precisely and concisely,
++    so that the following programs will be less obscure. For each legal
++    breakpoint~|p| in the paragraph, we define two quantities $\alpha(p)$ and
++    $\beta(p)$ such that the length of material in a line from breakpoint~|p| to
++    breakpoint~|q| is $\gamma+\beta(q)-\alpha(p)$, for some fixed $\gamma$.
++    Intuitively, $\alpha(p)$ and $\beta(q)$ are the total length of material from
++    the beginning of the paragraph to a point ``after'' a break at |p| and to a
++    point ``before'' a break at |q|; and $\gamma$ is the width of an empty line,
++    namely the length contributed by \.{\\leftskip} and \.{\\rightskip}.
++
++    Suppose, for example, that the paragraph consists entirely of alternating
++    boxes and glue skips; let the boxes have widths $x_1\ldots x_n$ and let the
++    skips have widths $y_1\ldots y_n$, so that the paragraph can be represented
++    by $x_1y_1\ldots x_ny_n$. Let $p_i$ be the legal breakpoint at $y_i$; then
++    $\alpha(p_i)=x_1+y_1+\cdots+x_i+y_i$, and $\beta(p_i)= x_1+y_1+\cdots+x_i$.
++    To check this, note that the length of material from $p_2$ to $p_5$, say, is
++    $\gamma+x_3+y_3+x_4+y_4+x_5=\gamma+\beta(p_5) -\alpha(p_2)$.
++
++    The quantities $\alpha$, $\beta$, $\gamma$ involve glue stretchability and
++    shrinkability as well as a natural width. If we were to compute $\alpha(p)$
++    and $\beta(p)$ for each |p|, we would need multiple precision arithmetic, and
++    the multiprecise numbers would have to be kept in the active nodes. \TeX\
++    avoids this problem by working entirely with relative differences or
++    ``deltas.'' Suppose, for example, that the active list contains
++    $a_1\,\delta_1\,a_2\,\delta_2\,a_3$, where the |a|'s are active breakpoints
++    and the $\delta$'s are delta nodes. Then $\delta_1=\alpha(a_1)-\alpha(a_2)$
++    and $\delta_2=\alpha(a_2)-\alpha(a_3)$. If the line breaking algorithm is
++    currently positioned at some other breakpoint |p|, the |active_width| array
++    contains the value $\gamma+\beta(p)-\alpha(a_1)$. If we are scanning through
++    the list of active nodes and considering a tentative line that runs from
++    $a_2$ to~|p|, say, the |cur_active_width| array will contain the value
++    $\gamma+\beta(p)-\alpha(a_2)$. Thus, when we move from $a_2$ to $a_3$, we
++    want to add $\alpha(a_2)-\alpha(a_3)$ to |cur_active_width|; and this is just
++    $\delta_2$, which appears in the active list between $a_2$ and $a_3$. The
++    |background| array contains $\gamma$. The |break_width| array will be used to
++    calculate values of new delta nodes when the active list is being updated.
++
++    The heart of the line-breaking procedure is `|try_break|', a subroutine that
++    tests if the current breakpoint |cur_p| is feasible, by running through the
++    active list to see what lines of text can be made from active nodes
++    to~|cur_p|. If feasible breaks are possible, new break nodes are created. If
++    |cur_p| is too far from an active node, that node is deactivated.
++
++    The parameter |pi| to |try_break| is the penalty associated with a break at
++    |cur_p|; we have |pi=eject_penalty| if the break is forced, and
++    |pi=inf_penalty| if the break is illegal.
++
++    The other parameter, |break_type|, is set to |hyphenated_node| or
++    |unhyphenated_node|, depending on whether or not the current break is at a
++    |disc_node|. The end of a paragraph is also regarded as `|hyphenated_node|';
++    this case is distinguishable by the condition |cur_p=null|.

++    as the length of a line ``from |cur_p| to |cur_p|''; we call it the
++    |break_width| at |cur_p|.
++
++    The |break_width| is usually negative, since it consists of the background
++    (which is normally zero) minus the width of nodes following~|cur_p| that are
++    eliminated after a break. If, for example, node |cur_p| is a glue node, the

+-
+-@ We come now to what is probably the most interesting algorithm of \TeX:
+-the mechanism for choosing the ``best possible'' breakpoints that yield
+-the individual lines of a paragraph. \TeX's line-breaking algorithm takes
+-a given horizontal list and converts it to a sequence of boxes that are
+-appended to the current vertical list. In the course of doing this, it
+-creates a special data structure containing three kinds of records that are
+-not used elsewhere in \TeX. Such nodes are created while a paragraph is
+-being processed, and they are destroyed afterwards; thus, the other parts
+-of \TeX\ do not need to know anything about how line-breaking is done.
+-
+-The method used here is based on an approach devised by Michael F. Plass and
+-@^Plass, Michael Frederick@>
+-@^Knuth, Donald Ervin@>
+-the author in 1977, subsequently generalized and improved by the same two
+-people in 1980. A detailed discussion appears in {\sl SOFTWARE---Practice
+-\AM\ Experience \bf11} (1981), 1119--1184, where it is shown that the
+-line-breaking problem can be regarded as a special case of the problem of
+-computing the shortest path in an acyclic network. The cited paper includes
+-numerous examples and describes the history of line breaking as it has been
+-practiced by printers through the ages. The present implementation adds two
+-new ideas to the algorithm of 1980: Memory space requirements are considerably
+-reduced by using smaller records for inactive nodes than for active ones,
+-and arithmetic overflow is avoided by using ``delta distances'' instead of
+-keeping track of the total distance from the beginning of the paragraph to the
+-current point.
+-
+-The |line_break| procedure should be invoked only in horizontal mode; it
+-leaves that mode and places its output into the current vlist of the
+-enclosing vertical mode (or internal vertical mode).
+-There is one explicit parameter:  |d| is true for partial paragraphs
+-preceding display math mode; in this case the amount of additional
+-penalty inserted before the final line is |display_widow_penalty|
+-instead of |widow_penalty|.
+-
+-There are also a number of implicit parameters: The hlist to be broken
+-starts at |vlink(head)|, and it is nonempty. The value of |prev_graf| in the
+-enclosing semantic level tells where the paragraph should begin in the
+-sequence of line numbers, in case hanging indentation or \.{\\parshape}
+-are in use; |prev_graf| is zero unless this paragraph is being continued
+-after a displayed formula.  Other implicit parameters, such as the
+-|par_shape_ptr| and various penalties to use for hyphenation, etc., appear
+-in |eqtb|.
+-
+-After |line_break| has acted, it will have updated the current vlist and the
+-value of |prev_graf|. Furthermore, the global variable |just_box| will
+-point to the final box created by |line_break|, so that the width of this
+-line can be ascertained when it is necessary to decide whether to use
+-|above_display_skip| or |above_display_short_skip| before a displayed formula.
+-
+-@c
+-halfword just_box;              /* the |hlist_node| for the last line of the new paragraph */
+-
+-@ In it's complete form, |line_break| is a rather lengthy
+-procedure---sort of a small world unto itself---we must build it up
+-little by little. Below you see only the general outline.
+-
+-The main task performed here is to move the list from |head| to
+-|temp_head| and go into the enclosing semantic level. We also append
+-the \.{\\parfillskip} glue to the end of the paragraph, removing a
+-space (or other glue node) if it was there, since spaces usually
+-precede blank lines and instances of `\.{\$\$}'. The |par_fill_skip|
+-is preceded by an infinite penalty, so it will never be considered as
+-a potential breakpoint.
+-
+-That code assumes that a |glue_node| and a |penalty_node| occupy the
+-same number of |mem|~words.
+-@^data structure assumptions@>

+-   or |disc_node|); the ordinal number of the line that will follow this
+-   breakpoint; and the fitness classification of the line that has just

+-@ The algorithm essentially determines the best possible way to achieve
+-   each feasible combination of position, line, and fitness. Thus, it answers
+-   questions like, ``What is the best way to break the opening part of the
+-   paragraph so that the fourth line is a tight line ending at such-and-such
+-   a place?'' However, the fact that all lines are to be the same length
+-   after a certain point makes it possible to regard all sufficiently large
+-   line numbers as equivalent, when the looseness parameter is zero, and this
+-   makes it possible for the algorithm to save space and time.
+-
+-   An ``active node'' and a ``passive node'' are created in |mem| for each
+-   feasible breakpoint that needs to be considered. Active nodes are three
+-   words long and passive nodes are two words long. We need active nodes only
+-   for breakpoints near the place in the paragraph that is currently being
+-   examined, so they are recycled within a comparatively short time after
+-   they are created.
+-
+-@ An active node for a given breakpoint contains six fields:
+-
+-|vlink| points to the next node in the list of active nodes; the
+-last active node has |vlink=active|.
+-
+-|break_node| points to the passive node associated with this
+-breakpoint.
+-
+-|line_number| is the number of the line that follows this
+-breakpoint.
+-
+-|fitness| is the fitness classification of the line ending at this
+-breakpoint.
+-
+-|type| is either |hyphenated_node| or |unhyphenated_node|, depending on
+-whether this breakpoint is a |disc_node|.
+-
+-|total_demerits| is the minimum possible sum of demerits over all
+-lines leading from the beginning of the paragraph to this breakpoint.
+-
+-The value of |vlink(active)| points to the first active node on a vlinked list
+-of all currently active nodes. This list is in order by |line_number|,
+-except that nodes with |line_number>easy_line| may be in any order relative
+-to each other.
+-
+-@c
+-void initialize_active(void)
+-{
+-    type(active) = hyphenated_node;
+-    line_number(active) = max_halfword;
+-    subtype(active) = 0;        /* the |subtype| is never examined */
+-}
+-
+-@ The passive node for a given breakpoint contains EIGHT fields:
+-
+-|vlink| points to the passive node created just before this one,
+-if any, otherwise it is |null|.
+-
+-|cur_break| points to the position of this breakpoint in the
+-horizontal list for the paragraph being broken.
+-
+-|prev_break| points to the passive node that should precede this
+-one in an optimal path to this breakpoint.
+-
+-|serial| is equal to |n| if this passive node is the |n|th
+-one created during the current pass. (This field is used only when
+-printing out detailed statistics about the line-breaking calculations.)
+-
+-|passive_pen_inter| holds the current \.{\\localinterlinepenalty}
+-
+-|passive_pen_broken| holds the current \.{\\localbrokenpenalty}
+-
+-There is a global variable called |passive| that points to the most
+-recently created passive node. Another global variable, |printed_node|,
+-is used to help print out the paragraph when detailed information about
+-the line-breaking computation is being displayed.
+-
+-@c
+-static halfword passive;        /* most recent node on passive list */
+-static halfword printed_node;   /*most recent node that has been printed */
+-static halfword pass_number;    /*the number of passive nodes allocated on this pass */
+-
+-@ The active list also contains ``delta'' nodes that help the algorithm
+-compute the badness of individual lines. Such nodes appear only between two
+-active nodes, and they have |type=delta_node|. If |p| and |r| are active nodes
+-and if |q| is a delta node between them, so that |vlink(p)=q| and |vlink(q)=r|,
+-then |q| tells the space difference between lines in the horizontal list that
+-start after breakpoint |p| and lines that start after breakpoint |r|. In
+-other words, if we know the length of the line that starts after |p| and
+-ends at our current position, then the corresponding length of the line that
+-starts after |r| is obtained by adding the amounts in node~|q|. A delta node
+-contains seven scaled numbers, since it must record the net change in glue
+-stretchability with respect to all orders of infinity. The natural width
+-difference appears in |mem[q+1].sc|; the stretch differences in units of
+-pt, sfi, fil, fill, and filll appear in |mem[q+2..q+6].sc|; and the shrink
+-difference appears in |mem[q+7].sc|. The |subtype| field of a delta node
+-is not used.
+-
+-Actually, we have two more fields that are used by |pdftex|.
+-
+-As the algorithm runs, it maintains a set of seven delta-like registers
+-for the length of the line following the first active breakpoint to the
+-current position in the given hlist. When it makes a pass through the
+-active list, it also maintains a similar set of seven registers for the
+-length following the active breakpoint of current interest. A third set
+-holds the length of an empty line (namely, the sum of \.{\\leftskip} and
+-\.{\\rightskip}); and a fourth set is used to create new delta nodes.
+-
+-When we pass a delta node we want to do operations like
+-$$\hbox{\ignorespaces|for
+-k:=1 to 7 do cur_active_width[k]:=cur_active_width[k]+mem[q+k].sc|};$$ and we
+-want to do this without the overhead of |for| loops. The |do_all_six|
+-macro makes such six-tuples convenient.
+-
+-@c
+-static scaled active_width[10] = { 0 }; /*distance from first active node to~|cur_p| */
+-static scaled background[10] = { 0 };   /*length of an ``empty'' line */
+-static scaled break_width[10] = { 0 };  /*length being computed after current break */
+-
+-static boolean auto_breaking;   /*make |auto_breaking| accessible out of |line_break| */
+-
+-@  Let's state the principles of the delta nodes more precisely and concisely,
+-   so that the following programs will be less obscure. For each legal
+-   breakpoint~|p| in the paragraph, we define two quantities $\alpha(p)$ and
+-   $\beta(p)$ such that the length of material in a line from breakpoint~|p|
+-   to breakpoint~|q| is $\gamma+\beta(q)-\alpha(p)$, for some fixed $\gamma$.
+-   Intuitively, $\alpha(p)$ and $\beta(q)$ are the total length of material from
+-   the beginning of the paragraph to a point ``after'' a break at |p| and to a
+-   point ``before'' a break at |q|; and $\gamma$ is the width of an empty line,
+-   namely the length contributed by \.{\\leftskip} and \.{\\rightskip}.
+-
+-   Suppose, for example, that the paragraph consists entirely of alternating
+-   boxes and glue skips; let the boxes have widths $x_1\ldots x_n$ and
+-   let the skips have widths $y_1\ldots y_n$, so that the paragraph can be
+-   represented by $x_1y_1\ldots x_ny_n$. Let $p_i$ be the legal breakpoint
+-   at $y_i$; then $\alpha(p_i)=x_1+y_1+\cdots+x_i+y_i$, and $\beta(p_i)=
+-   x_1+y_1+\cdots+x_i$. To check this, note that the length of material from
+-   $p_2$ to $p_5$, say, is $\gamma+x_3+y_3+x_4+y_4+x_5=\gamma+\beta(p_5)
+-   -\alpha(p_2)$.
+-
+-   The quantities $\alpha$, $\beta$, $\gamma$ involve glue stretchability and
+-   shrinkability as well as a natural width. If we were to compute $\alpha(p)$
+-   and $\beta(p)$ for each |p|, we would need multiple precision arithmetic, and
+-   the multiprecise numbers would have to be kept in the active nodes.
+-   \TeX\ avoids this problem by working entirely with relative differences
+-   or ``deltas.'' Suppose, for example, that the active list contains
+-   $a_1\,\delta_1\,a_2\,\delta_2\,a_3$, where the |a|'s are active breakpoints
+-   and the $\delta$'s are delta nodes. Then $\delta_1=\alpha(a_1)-\alpha(a_2)$
+-   and $\delta_2=\alpha(a_2)-\alpha(a_3)$. If the line breaking algorithm is
+-   currently positioned at some other breakpoint |p|, the |active_width| array
+-   contains the value $\gamma+\beta(p)-\alpha(a_1)$. If we are scanning through
+-   the list of active nodes and considering a tentative line that runs from
+-   $a_2$ to~|p|, say, the |cur_active_width| array will contain the value
+-   $\gamma+\beta(p)-\alpha(a_2)$. Thus, when we move from $a_2$ to $a_3$,
+-   we want to add $\alpha(a_2)-\alpha(a_3)$ to |cur_active_width|; and this
+-   is just $\delta_2$, which appears in the active list between $a_2$ and
+-   $a_3$. The |background| array contains $\gamma$. The |break_width| array
+-   will be used to calculate values of new delta nodes when the active
+-   list is being updated.
+-
+-@  The heart of the line-breaking procedure is `|try_break|', a subroutine
+-   that tests if the current breakpoint |cur_p| is feasible, by running
+-   through the active list to see what lines of text can be made from active
+-   nodes to~|cur_p|.  If feasible breaks are possible, new break nodes are
+-   created.  If |cur_p| is too far from an active node, that node is
+-   deactivated.
+-
+-   The parameter |pi| to |try_break| is the penalty associated
+-   with a break at |cur_p|; we have |pi=eject_penalty| if the break is forced,
+-   and |pi=inf_penalty| if the break is illegal.
+-
+-   The other parameter, |break_type|, is set to |hyphenated_node| or |unhyphenated_node|,
+-   depending on whether or not the current break is at a |disc_node|. The
+-   end of a paragraph is also regarded as `|hyphenated_node|'; this case is
+-   distinguishable by the condition |cur_p=null|.

+-@  As we consider various ways to end a line at |cur_p|, in a given line number

+-   line breaks ending at |cur_p| with a |tight_fit| line; |best_place[tight_fit]|
+-   points to the passive node for the break before~|cur_p| that achieves such

+-   keeps track of the smallest value in the |minimal_demerits| array.

++This is where the action starts. We're speaking of \LUATEX, a continuation of
++\PDFTEX\ (which included \ETEX) and \ALEPH. As \TEX, \LUATEX\ is a document
++compiler intended to simplify high quality typesetting for many of the world's
++languages. It is an extension of D. E. Knuth's \TEX, which was designed
++essentially for the typesetting of languages using the Latin alphabet. Although
++it is a direct decendant of \TEX, and therefore mostly compatible, there are
++some subtle differences that relate to \UNICODE\ support and \OPENTYPE\ math.
++
++The \ALEPH\ subsystem loosens many of the restrictions imposed by~\TeX: register
++numbers are no longer limited to 8~bits. Fonts may have more than 256~characters,
++more than 256~fonts may be used, etc. We use a similar model. We also borrowed
++the directional model but have upgraded it a bit as well as integrated it more
++tightly.
++
++This program is directly derived from Donald E. Knuth's \TEX; the change history
++which follows and the reward offered for finders of bugs refer specifically to
++\TEX; they should not be taken as referring to \LUATEX, \PDFTEX, nor \ETEX,
++although the change history is relevant in that it demonstrates the evolutionary
++path followed. This program is not \TEX; that name is reserved strictly for the
++program which is the creation and sole responsibility of Professor Knuth.

++Although considerable effort has been expended to make the LuaTeX program correct
++and reliable, no warranty is implied; the authors disclaim any obligation or
++liability for damages, including but not limited to special, indirect, or
++consequential damages arising out of or in connection with the use or performance
++of this software. This work has been a ``labor of love'' and the authors hope
++that users enjoy it.
++
++{\em You will find a lot of comments that originate in original \TEX. We kept them
++as a side effect of the conversion from \WEB\ to \CWEB. Because there is not much
++webbing going on here eventually the files became regular \CCODE\ files with still
++potentially typeset comments. As we add our own comments, and also comments are
++there from \PDFTEX, \ALEPH\ and \ETEX, we get a curious mix. The best comments are
++of course from Don Knuth. All bad comments are ours. All errors are ours too!
++
++Not all comments make sense, because some things are implemented differently, for
++instance some memory management. But the principles of tokens and nodes stayed.
++It anyway means that you sometimes need to keep in mind that the explanation is
++more geared to traditional \TEX. But that's not a bad thing. Sorry Don for any
++confusion we introduced. The readers should have a copy of the \TEX\ books at hand
++anyway.}
++
++A large piece of software like \TeX\ has inherent complexity that cannot be
++reduced below a certain level of difficulty, although each individual part is
++fairly simple by itself. The \.{WEB} language is intended to make the algorithms
++as readable as possible, by reflecting the way the individual program pieces fit
++together and by providing the cross-references that connect different parts.
++Detailed comments about what is going on, and about why things were done in
++certain ways, have been liberally sprinkled throughout the program. These
++comments explain features of the implementation, but they rarely attempt to
++explain the \TeX\ language itself, since the reader is supposed to be familiar
++with {\sl The \TeX book}.
++
++The present implementation has a long ancestry, beginning in the summer of~1977,
++when Michael~F. Plass and Frank~M. Liang designed and coded a prototype @^Plass,
++Michael Frederick@> @^Liang, Franklin Mark@> @^Knuth, Donald Ervin@> based on
++some specifications that the author had made in May of that year. This original
++proto\TeX\ included macro definitions and elementary manipulations on boxes and
++glue, but it did not have line-breaking, page-breaking, mathematical formulas,
++alignment routines, error recovery, or the present semantic nest; furthermore, it
++used character lists instead of token lists, so that a control sequence like
++\.{\\halign} was represented by a list of seven characters. A complete version of
++\TeX\ was designed and coded by the author in late 1977 and early 1978; that
++program, like its prototype, was written in the {\mc SAIL} language, for which an
++excellent debugging system was available. Preliminary plans to convert the {\mc
++SAIL} code into a form somewhat like the present ``web'' were developed by Luis
++Trabb~Pardo and @^Trabb Pardo, Luis Isidoro@> the author at the beginning of
++1979, and a complete implementation was created by Ignacio~A. Zabala in 1979 and
++1980. The \TeX82 program, which @^Zabala Salelles, Ignacio Andr\'es@> was written
++by the author during the latter part of 1981 and the early part of 1982, also
++incorporates ideas from the 1979 implementation of @^Guibas, Leonidas Ioannis@>
++@^Sedgewick, Robert@> @^Wyatt, Douglas Kirk@> \TeX\ in {\mc MESA} that was
++written by Leonidas Guibas, Robert Sedgewick, and Douglas Wyatt at the Xerox Palo
++Alto Research Center. Several hundred refinements were introduced into \TeX82
++based on the experiences gained with the original implementations, so that
++essentially every part of the system has been substantially improved. After the
++appearance of ``Version 0'' in September 1982, this program benefited greatly
++from the comments of many other people, notably David~R. Fuchs and Howard~W.
++Trickey. A final revision in September 1989 extended the input character set to
++eight-bit codes and introduced the ability to hyphenate words from different
++languages, based on some ideas of Michael~J. Ferguson. @^Fuchs, David Raymond@>
++@^Trickey, Howard Wellington@> @^Ferguson, Michael John@>
++
++No doubt there still is plenty of room for improvement, but the author is firmly
++committed to keeping \TeX82 ``frozen'' from now on; stability and reliability are
++to be its main virtues.
++On the other hand, the \.{WEB} description can be extended without changing the
++core of \TeX82 itself, and the program has been designed so that such extensions
++are not extremely difficult to make. The |banner| string defined here should be
++changed whenever \TeX\ undergoes any modifications, so that it will be clear
++which version of \TeX\ might be the guilty party when a problem arises.

++This program contains code for various features extending \TeX, therefore this

++reserved for software systems that are fully compatible with each other. A
++special test suite called the ``\.{TRIP} test'' is available for helping to
++determine whether a particular implementation deserves to be known as `\TeX'
++[cf.~Stanford Computer Science report CS1027, November 1984].

++We have noted that there are two versions of \TeX82. One, called \.{INITEX},

++handled by \LUA\ code and therefore not present in the format.

+-
+-e-TeX is copyright (C) 1994,98 by Peter Breitenlohner.
+-
+-This is LuaTeX, a continuation of $\pdfTeX$ and $\Aleph$.  LuaTeX is a
+-document compiler intended to simplify high-quality typesetting for
+-many of the world's languages.  It is an extension of D. E. Knuth's
+-\TeX, which was designed essentially for the typesetting of languages
+-using the Latin alphabet.
+-
+-The $\Aleph$ subsystem loosens many of the restrictions imposed by~\TeX:
+-register numbers are no longer limited to 8~bits;  fonts may have more
+-than 256~characters;  more than 256~fonts may be used;  etc.
+-
+-% This program is directly derived from Donald E. Knuth's TeX;
+-% the change history which follows and the reward offered for finders of
+-% bugs refer specifically to TeX; they should not be taken as referring
+-% to LuaTeX, pdfTeX, nor e-TeX, although the change history is relevant in that it
+-% demonstrates the evolutionary path followed.  This program is not TeX;
+-% that name is reserved strictly for the program which is the creation
+-% and sole responsibility of Professor Knuth.
+-

+-
+-A large piece of software like \TeX\ has inherent complexity that cannot
+-be reduced below a certain level of difficulty, although each individual
+-part is fairly simple by itself. The \.{WEB} language is intended to make
+-the algorithms as readable as possible, by reflecting the way the
+-individual program pieces fit together and by providing the
+-cross-references that connect different parts. Detailed comments about
+-what is going on, and about why things were done in certain ways, have
+-been liberally sprinkled throughout the program.  These comments explain
+-features of the implementation, but they rarely attempt to explain the
+-\TeX\ language itself, since the reader is supposed to be familiar with
+-{\sl The \TeX book}.

+-@:TeXbook}{\sl The \TeX book@>
+-
+-The present implementation has a long ancestry, beginning in the summer
+-of~1977, when Michael~F. Plass and Frank~M. Liang designed and coded
+-a prototype
+-@^Plass, Michael Frederick@>
+-@^Liang, Franklin Mark@>
+-@^Knuth, Donald Ervin@>
+-based on some specifications that the author had made in May of that year.
+-This original proto\TeX\ included macro definitions and elementary
+-manipulations on boxes and glue, but it did not have line-breaking,
+-page-breaking, mathematical formulas, alignment routines, error recovery,
+-or the present semantic nest; furthermore,
+-it used character lists instead of token lists, so that a control sequence
+-like \.{\\halign} was represented by a list of seven characters. A
+-complete version of \TeX\ was designed and coded by the author in late
+-1977 and early 1978; that program, like its prototype, was written in the
+-{\mc SAIL} language, for which an excellent debugging system was
+-available. Preliminary plans to convert the {\mc SAIL} code into a form
+-somewhat like the present ``web'' were developed by Luis Trabb~Pardo and
+-@^Trabb Pardo, Luis Isidoro@>
+-the author at the beginning of 1979, and a complete implementation was
+-created by Ignacio~A. Zabala in 1979 and 1980. The \TeX82 program, which
+-@^Zabala Salelles, Ignacio Andr\'es@>
+-was written by the author during the latter part of 1981 and the early
+-part of 1982, also incorporates ideas from the 1979 implementation of
+-@^Guibas, Leonidas Ioannis@>
+-@^Sedgewick, Robert@>
+-@^Wyatt, Douglas Kirk@>
+-\TeX\ in {\mc MESA} that was written by Leonidas Guibas, Robert Sedgewick,
+-and Douglas Wyatt at the Xerox Palo Alto Research Center.  Several hundred
+-refinements were introduced into \TeX82 based on the experiences gained with
+-the original implementations, so that essentially every part of the system
+-has been substantially improved. After the appearance of ``Version 0'' in
+-September 1982, this program benefited greatly from the comments of
+-many other people, notably David~R. Fuchs and Howard~W. Trickey.
+-A final revision in September 1989 extended the input character set to
+-eight-bit codes and introduced the ability to hyphenate words from
+-different languages, based on some ideas of Michael~J. Ferguson.
+-@^Fuchs, David Raymond@>
+-@^Trickey, Howard Wellington@>
+-@^Ferguson, Michael John@>
+-
+-No doubt there still is plenty of room for improvement, but the author
+-is firmly committed to keeping \TeX82 ``frozen'' from now on; stability
+-and reliability are to be its main virtues.
+-
+-On the other hand, the \.{WEB} description can be extended without changing
+-the core of \TeX82 itself, and the program has been designed so that such
+-extensions are not extremely difficult to make.
+-The |banner| string defined here should be changed whenever \TeX\
+-undergoes any modifications, so that it will be clear which version of
+-\TeX\ might be the guilty party when a problem arises.

+-This program contains code for various features extending \TeX,
+-therefore this program is called `\eTeX' and not
+-`\TeX'; the official name `\TeX' by itself is reserved
+-for software systems that are fully compatible with each other.
+-A special test suite called the ``\.{TRIP} test'' is available for
+-helping to determine whether a particular implementation deserves to be
+-known as `\TeX' [cf.~Stanford Computer Science report CS1027,

++\TeX\ is typically in the midst of building many lists at once. For example, when
++a math formula is being processed, \TeX\ is in math mode and working on an mlist;
++this formula has temporarily interrupted \TeX\ from being in horizontal mode and
++building the hlist of a paragraph; and this paragraph has temporarily interrupted
++\TeX\ from being in vertical mode and building the vlist for the next page of a
++document. Similarly, when a \.{\\vbox} occurs inside of an \.{\\hbox}, \TeX\ is
++temporarily interrupted from working in restricted horizontal mode, and it enters
++internal vertical mode. The ``semantic nest'' is a stack that keeps track of what
++lists and modes are currently suspended.
++
++At each level of processing we are in one of six modes:
++
++|vmode| stands for vertical mode (the page builder);
++
++|hmode| stands for horizontal mode (the paragraph builder);
++
++|mmode| stands for displayed formula mode;
++
++|-vmode| stands for internal vertical mode (e.g., in a \.{\\vbox});
++
++|-hmode| stands for restricted horizontal mode (e.g., in an \.{\\hbox});
++
++|-mmode| stands for math formula mode (not displayed).
++
++The mode is temporarily set to zero while processing \.{\\write} texts in the
++|ship_out| routine.
++
++Numeric values are assigned to |vmode|, |hmode|, and |mmode| so that \TeX's ``big
++semantic switch'' can select the appropriate thing to do by computing the value
++|abs(mode)+cur_cmd|, where |mode| is the current mode and |cur_cmd| is the
++current command code.

++
++The state of affairs at any semantic level can be represented by five values:
++
++|mode| is the number representing the semantic mode, as just explained.
++
++|head| is a |pointer| to a list head for the list being built; |link(head)|
++therefore points to the first element of the list, or to |null| if the list is
++empty.
++
++|tail| is a |pointer| to the final node of the list being built; thus,
++|tail=head| if and only if the list is empty.
++
++|prev_graf| is the number of lines of the current paragraph that have already
++been put into the present vertical list.
++
++|aux| is an auxiliary |memory_word| that gives further information that is needed
++to characterize the situation.
++
++In vertical mode, |aux| is also known as |prev_depth|; it is the scaled value
++representing the depth of the previous box, for use in baseline calculations, or
++it is |<=-1000|pt if the next box on the vertical list is to be exempt from
++baseline calculations. In horizontal mode, |aux| is also known as |space_factor|;
++it holds the current space factor used in spacing calculations. In math mode,
++|aux| is also known as |incompleat_noad|; if not |null|, it points to a record
++that represents the numerator of a generalized fraction for which the denominator
++is currently being formed in the current list.
++
++There is also a sixth quantity, |mode_line|, which correlates the semantic nest
++with the user's input; |mode_line| contains the source line number at which the
++current level of nesting was entered. The negative of this line number is the
++|mode_line| at the level of the user's output routine.
++
++A seventh quantity, |eTeX_aux|, is used by the extended features eTeX. In math
++mode it is known as |delim_ptr| and points to the most recent |fence_noad| of a
++|math_left_group|.
++
++In horizontal mode, the |prev_graf| field is used for initial language data.
++
++The semantic nest is an array called |nest| that holds the |mode|, |head|,
++|tail|, |prev_graf|, |aux|, and |mode_line| values for all semantic levels below
++the currently active one. Information about the currently active level is kept in
++the global quantities |mode|, |head|, |tail|, |prev_graf|, |aux|, and
++|mode_line|, which live in a struct that is ready to be pushed onto |nest| if
++necessary.
++
++The math field is used by various bits and pieces in |texmath.w|
++
++This implementation of \TeX\ uses two different conventions for representing
++sequential stacks. @^stack conventions@>@^conventions for representing stacks@>
++
++1) If there is frequent access to the top entry, and if the stack is essentially
++never empty, then the top entry is kept in a global variable (even better would
++be a machine register), and the other entries appear in the array
++$\\{stack}[0\to(\\{ptr}-1)]$. The semantic stack is handled this way.
++
++2) If there is infrequent top access, the entire stack contents are in the array
++$\\{stack}[0\to(\\{ptr}-1)]$. For example, the |save_stack| is treated this way,
++as we have seen.
++
++In |nest_ptr| we have the first unused location of |nest|, and |max_nest_stack|
++has the maximum of |nest_ptr| when pushing. In |shown_mode| we store the most
++recent mode shown by \.{\\tracingcommands} and with |save_tail| we can examine
++whether we have an auto kern before a glue.

++into two parts; the ``current page'' runs from |page_head| to |page_tail|, and
++the ``contribution list'' runs from |contrib_head| to |tail| of semantic level
++zero. The idea is that contributions are first formed in vertical mode, then

+-
+-@ \TeX\ is typically in the midst of building many lists at once. For example,
+-when a math formula is being processed, \TeX\ is in math mode and
+-working on an mlist; this formula has temporarily interrupted \TeX\ from
+-being in horizontal mode and building the hlist of a paragraph; and this
+-paragraph has temporarily interrupted \TeX\ from being in vertical mode
+-and building the vlist for the next page of a document. Similarly, when a
+-\.{\\vbox} occurs inside of an \.{\\hbox}, \TeX\ is temporarily
+-interrupted from working in restricted horizontal mode, and it enters
+-internal vertical mode.  The ``semantic nest'' is a stack that
+-keeps track of what lists and modes are currently suspended.
+-
+-At each level of processing we are in one of six modes:
+-
+-\yskip\hang|vmode| stands for vertical mode (the page builder);
+-
+-\hang|hmode| stands for horizontal mode (the paragraph builder);
+-
+-\hang|mmode| stands for displayed formula mode;
+-
+-\hang|-vmode| stands for internal vertical mode (e.g., in a \.{\\vbox});
+-
+-\hang|-hmode| stands for restricted horizontal mode (e.g., in an \.{\\hbox});
+-
+-\hang|-mmode| stands for math formula mode (not displayed).
+-
+-\yskip\noindent The mode is temporarily set to zero while processing \.{\\write}
+-texts in the |ship_out| routine.
+-
+-Numeric values are assigned to |vmode|, |hmode|, and |mmode| so that
+-\TeX's ``big semantic switch'' can select the appropriate thing to
+-do by computing the value |abs(mode)+cur_cmd|, where |mode| is the current
+-mode and |cur_cmd| is the current command code.

+-
+-@ The state of affairs at any semantic level can be represented by
+-five values:
+-
+-\yskip\hang|mode| is the number representing the semantic mode, as
+-just explained.
+-
+-\yskip\hang|head| is a |pointer| to a list head for the list being built;
+-|link(head)| therefore points to the first element of the list, or
+-to |null| if the list is empty.
+-
+-\yskip\hang|tail| is a |pointer| to the final node of the list being
+-built; thus, |tail=head| if and only if the list is empty.
+-
+-\yskip\hang|prev_graf| is the number of lines of the current paragraph that
+-have already been put into the present vertical list.
+-
+-\yskip\hang|aux| is an auxiliary |memory_word| that gives further information
+-that is needed to characterize the situation.
+-
+-\yskip\noindent
+-In vertical mode, |aux| is also known as |prev_depth|; it is the scaled
+-value representing the depth of the previous box, for use in baseline
+-calculations, or it is |<=-1000|pt if the next box on the vertical list is to
+-be exempt from baseline calculations.  In horizontal mode, |aux| is also
+-known as |space_factor|; it holds the current space factor used in
+-spacing calculations. In math mode, |aux| is also known as |incompleat_noad|;
+-if not |null|, it points to a record that represents the numerator of a
+-generalized fraction for which the denominator is currently being formed
+-in the current list.
+-
+-There is also a sixth quantity, |mode_line|, which correlates
+-the semantic nest with the user's input; |mode_line| contains the source
+-line number at which the current level of nesting was entered. The negative
+-of this line number is the |mode_line| at the level of the
+-user's output routine.
+-
+-A seventh quantity, |eTeX_aux|, is used by the extended features eTeX.
+-In math mode it is known as |delim_ptr| and points to the most
+-recent |fence_noad|  of a |math_left_group|.
+-
+-In horizontal mode, the |prev_graf| field is used for initial language data.
+-
+-The semantic nest is an array called |nest| that holds the |mode|, |head|,
+-|tail|, |prev_graf|, |aux|, and |mode_line| values for all semantic levels
+-below the currently active one. Information about the currently active
+-level is kept in the global quantities |mode|, |head|, |tail|, |prev_graf|,
+-|aux|, and |mode_line|, which live in a struct that is ready to
+-be pushed onto |nest| if necessary.
+-
+-The math field is used by various bits and pieces in |texmath.w|
+-
+-@ This implementation of
+-\TeX\ uses two different conventions for representing sequential stacks.
+-@^stack conventions@>@^conventions for representing stacks@>
+-
+-\yskip\hang 1) If there is frequent access to the top entry, and if the
+-stack is essentially never empty, then the top entry is kept in a global
+-variable (even better would be a machine register), and the other entries
+-appear in the array $\\{stack}[0\to(\\{ptr}-1)]$. The
+-semantic stack is handled this way.
+-
+-\yskip\hang 2) If there is infrequent top access, the entire stack contents
+-are in the array $\\{stack}[0\to(\\{ptr}-1)]$. For example, the |save_stack|
+-is treated this way, as we have seen.
+-
+-@c
+-list_state_record *nest;
+-int nest_ptr;                   /* first unused location of |nest| */
+-int max_nest_stack;             /* maximum of |nest_ptr| when pushing */
+-int shown_mode;                 /* most recent mode shown by \.{\\tracingcommands} */
+-halfword save_tail;             /* save |tail| so we can examine whether we have an auto
+-                                   kern before a glue */
+-
+-@ We will see later that the vertical list at the bottom semantic level is split
+-into two parts; the ``current page'' runs from |page_head| to |page_tail|,
+-and the ``contribution list'' runs from |contrib_head| to |tail| of
+-semantic level zero. The idea is that contributions are first formed in
+-vertical mode, then ``contributed'' to the current page (during which time
+-the page-breaking decisions are made). For now, we don't need to know
+-any more details about the page-building process.

+-

+-    cur_list.tail_field = vlink(cur_list.tail_field);

+-        if (vlink(alink(cur_list.tail_field)) == cur_list.tail_field) {
+-            n = alink(cur_list.tail_field);
+-        } else {
+-            n = cur_list.head_field;
+-            while (vlink(n) != cur_list.tail_field)
+-                n = vlink(n);
+-        }

+-        vlink(n) = null;
+-        return r;
+-    } else {
+-        return null;
+-    }
+-}
+-
+-@ When \TeX's work on one level is interrupted, the state is saved by
+-calling |push_nest|. This routine changes |head| and |tail| so that
+-a new (empty) list is begun; it does not change |mode| or |aux|.
+-
+-@c
+-void push_nest(void)
+-{                               /* enter a new semantic level, save the old */
+-    if (nest_ptr > max_nest_stack) {
+-        max_nest_stack = nest_ptr;

+-            overflow("semantic nest size", (unsigned) nest_size);

+-
+-@ Conversely, when \TeX\ is finished on the current level, the former
+-state is restored by calling |pop_nest|. This routine will never be

+-is a node that should be returned to free memory.

+-@ We're essentially done with the parts of \TeX\ that are concerned with the
+-input (|get_next|) and the output (|ship_out|). So it's time to get heavily into
+-the remaining part, which does the real work of typesetting.
+-
+-After lists are constructed, \TeX\ wraps them up and puts them into boxes. Two
+-major subroutines are given the responsibility for this task: |hpack| applies to
+-horizontal lists (hlists) and |vpack| applies to vertical lists (vlists). The
+-main duty of |hpack| and |vpack| is to compute the dimensions of the resulting
+-boxes, and to adjust the glue if one of those dimensions is pre-specified. The
+-computed sizes normally enclose all of the material inside the new box; but some
+-items may stick out if negative glue is used, if the box is overfull, or if a
+-\.{\\vbox} includes other boxes that have been shifted left.
+-
+-The subroutine call |hpack(p,w,m)| returns a pointer to an |hlist_node| for a box
+-containing the hlist that starts at |p|. Parameter |w| specifies a width; and
+-parameter |m| is either `|exactly|' or `|additional|'. Thus, |hpack(p,w,exactly)|
+-produces a box whose width is exactly |w|, while |hpack(p,w,additional)| yields a
+-box whose width is the natural width plus |w|. It is convenient to define a macro
+-called `|natural|' to cover the most common case, so that we can say
+-|hpack(p,natural)| to get a box that has the natural width of list |p|.
+-
+-Similarly, |vpack(p,w,m)| returns a pointer to a |vlist_node| for a box
+-containing the vlist that starts at |p|. In this case |w| represents a height
+-instead of a width; the parameter |m| is interpreted as in |hpack|.
+-
+-@ The parameters to |hpack| and |vpack| correspond to \TeX's primitives like
+-`\.{\\hbox} \.{to} \.{300pt}', `\.{\\hbox} \.{spread} \.{10pt}'; note that
+-`\.{\\hbox}' with no dimension following it is equivalent to `\.{\\hbox}
+-\.{spread} \.{0pt}'. The |scan_spec| subroutine scans such constructions in the
+-user's input, including the mandatory left brace that follows them, and it puts
+-the specification onto |save_stack| so that the desired box can later be obtained
+-by executing the following code: $$\vbox{\halign{#\hfil\cr

++    The kern stretch / shrink code was (or had become) rather weird ... the width
++    field is set, and then used in a second calculation, repeatedly, so why is
++    that ... maybe some some weird left-over ... anyway, the values are so small
++    that in practice they are not significant at all when the backend sees them
++    because a few hundred sp positive or negative are just noise there (so
++    adjustlevel 3 has hardly any consequence for the result but is more
++    efficient).

++So far we have gotten a little way into the |line_break| routine, having covered

++called |auto_breaking| is set to true except within math formulas, since glue
++nodes are not legal breakpoints when they appear in formulas.
+ 
+ The current node of interest in the hlist is pointed to by |cur_p|. Another
+-variable, |prev_p|, is usually one step behind |cur_p|, but the real
+-meaning of |prev_p| is this: If |type(cur_p)=glue_node| then |cur_p| is a legal
+-breakpoint if and only if |auto_breaking| is true and |prev_p| does not
+-point to a glue node, penalty node, explicit kern node, or math node.

++if and only if |auto_breaking| is true and |prev_p| does not point to a glue
++node, penalty node, explicit kern node, or math node.
++
++The total number of lines that will be set by |post_line_break| is
++|best_line-prev_graf-1|. The last breakpoint is specified by
++|break_node(best_bet)|, and this passive node points to the other breakpoints via
++the |prev_break| links. The finishing-up phase starts by linking the relevant
++passive nodes in forward order, changing |prev_break| to |next_break|. (The
++|next_break| fields actually reside in the same memory space as the |prev_break|
++fields did, but we give them a new name because of their new significance.) Then
++the lines are justified, one by one.

++
++Control sequences are stored and retrieved by means of a fairly standard hash
++table algorithm called the method of ``coalescing lists'' (cf.\ Algorithm 6.4C in
++{\sl The Art of Computer Programming\/}). Once a control sequence enters the
++table, it is never removed, because there are complicated situations involving
++\.{\\gdef} where the removal of a control sequence at the end of a group would be
++a mistake preventable only by the introduction of a complicated reference-count
++mechanism.
++
++The actual sequence of letters forming a control sequence identifier is stored in
++the |str_pool| array together with all the other strings. An auxiliary array
++|hash| consists of items with two halfword fields per word. The first of these,
++called |next(p)|, points to the next identifier belonging to the same coalesced
++list as the identifier corresponding to~|p|; and the other, called |text(p)|,
++points to the |str_start| entry for |p|'s identifier. If position~|p| of the hash
++table is empty, we have |text(p)=0|; if position |p| is either empty or the end
++of a coalesced hash list, we have |next(p)=0|. An auxiliary pointer variable
++called |hash_used| is maintained in such a way that all locations |p>=hash_used|
++are nonempty. The global variable |cs_count| tells how many multiletter control
++sequences have been defined, if statistics are being kept.
++
++A global boolean variable called |no_new_control_sequence| is set to |true|
++during the time that new hash table entries are forbidden.

+-
+-@ Control sequences are stored and retrieved by means of a fairly standard hash
+-table algorithm called the method of ``coalescing lists'' (cf.\ Algorithm 6.4C
+-in {\sl The Art of Computer Programming\/}). Once a control sequence enters the
+-table, it is never removed, because there are complicated situations
+-involving \.{\\gdef} where the removal of a control sequence at the end of
+-a group would be a mistake preventable only by the introduction of a
+-complicated reference-count mechanism.
+-
+-The actual sequence of letters forming a control sequence identifier is
+-stored in the |str_pool| array together with all the other strings. An
+-auxiliary array |hash| consists of items with two halfword fields per
+-word. The first of these, called |next(p)|, points to the next identifier
+-belonging to the same coalesced list as the identifier corresponding to~|p|;
+-and the other, called |text(p)|, points to the |str_start| entry for
+-|p|'s identifier. If position~|p| of the hash table is empty, we have
+-|text(p)=0|; if position |p| is either empty or the end of a coalesced
+-hash list, we have |next(p)=0|. An auxiliary pointer variable called
+-|hash_used| is maintained in such a way that all locations |p>=hash_used|
+-are nonempty. The global variable |cs_count| tells how many multiletter
+-control sequences have been defined, if statistics are being kept.
+-
+-A global boolean variable called |no_new_control_sequence| is set to
+-|true| during the time that new hash table entries are forbidden.

++
++    The next routine `|scan_something_internal|' is used to fetch internal
++    numeric quantities like `\.{\\hsize}', and also to handle the `\.{\\the}'
++    when expanding constructions like `\.{\\the\\toks0}' and
++    `\.{\\the\\baselineskip}'. Soon we will be considering the |scan_int|
++    procedure, which calls |scan_something_internal|; on the other hand,
++    |scan_something_internal| also calls |scan_int|, for constructions like
++    `\.{\\catcode\`\\\$}' or `\.{\\fontdimen} \.3 \.{\\ff}'. So we have to
++    declare |scan_int| as a |forward| procedure. A few other procedures are also
++    declared at this point.
++
++    \TeX\ doesn't know exactly what to expect when |scan_something_internal|
++    begins. For example, an integer or dimension or glue value could occur
++    immediately after `\.{\\hskip}'; and one can even say \.{\\the} with respect
++    to token lists in constructions like `\.{\\xdef\\o\{\\the\\output\}}'. On the
++    other hand, only integers are allowed after a construction like
++    `\.{\\count}'. To handle the various possibilities, |scan_something_internal|
++    has a |level| parameter, which tells the ``highest'' kind of quantity that
++    |scan_something_internal| is allowed to produce. Eight levels are
++    distinguished, namely |int_val|, |attr_val|, |dimen_val|, |glue_val|,
++    |mu_val|, |dir_val|, |ident_val|, and |tok_val|.
++
++    The output of |scan_something_internal| (and of the other routines
++    |scan_int|, |scan_dimen|, and |scan_glue| below) is put into the global
++    variable |cur_val|, and its level is put into |cur_val_level|. The highest
++    values of |cur_val_level| are special: |mu_val| is used only when |cur_val|
++    points to something in a ``muskip'' register, or to one of the three
++    parameters \.{\\thinmuskip}, \.{\\medmuskip}, \.{\\thickmuskip}; |ident_val|
++    is used only when |cur_val| points to a font identifier; |tok_val| is used
++    only when |cur_val| points to |null| or to the reference count of a token
++    list. The last two cases are allowed only when |scan_something_internal| is
++    called with |level=tok_val|.
++
++    If the output is glue, |cur_val| will point to a glue specification, and the
++    reference count of that glue will have been updated to reflect this
++    reference; if the output is a nonempty token list, |cur_val| will point to
++    its reference count, but in this case the count will not have been updated.
++    Otherwise |cur_val| will contain the integer or scaled value in question.

+-@ Let's turn now to some procedures that \TeX\ calls upon frequently to digest
+-certain kinds of patterns in the input. Most of these are quite simple;
+-some are quite elaborate. Almost all of the routines call |get_x_token|,
+-which can cause them to be invoked recursively.
+-
+-The |scan_left_brace| routine is called when a left brace is supposed to be
+-the next non-blank token. (The term ``left brace'' means, more precisely,
+-a character whose catcode is |left_brace|.) \TeX\ allows \.{\\relax} to
+-appear before the |left_brace|.
+-
+-@c
+-void scan_left_brace(void)
+-{                               /* reads a mandatory |left_brace| */
+-    /* Get the next non-blank non-relax non-call token */
+-    do {
+-        get_x_token();
+-    } while ((cur_cmd == spacer_cmd) || (cur_cmd == relax_cmd));
+-
+-    if (cur_cmd != left_brace_cmd) {
+-        print_err("Missing { inserted");
+-        help4("A left brace was mandatory here, so I've put one in.",
+-              "You might want to delete and/or insert some corrections",
+-              "so that I will find a matching right brace soon.",
+-              "If you're confused by all this, try typing `I}' now.");
+-        back_error();
+-        cur_tok = left_brace_token + '{';
+-        cur_cmd = left_brace_cmd;
+-        cur_chr = '{';
+-        incr(align_state);
+-    }
+-}
+-
+-@ The |scan_optional_equals| routine looks for an optional `\.=' sign preceded
+-by optional spaces; `\.{\\relax}' is not ignored here.
+-
+-@c
+-void scan_optional_equals(void)
+-{
+-    /* Get the next non-blank non-call token */
+-    do {
+-        get_x_token();
+-    } while (cur_cmd == spacer_cmd);
+-    if (cur_tok != other_token + '=')
+-        back_input();
+-}
+-
+-@ Here is a procedure that sounds an alarm when mu and non-mu units
+-are being switched.
+-
+-@c
+-static void mu_error(void)
+-{
+-    print_err("Incompatible glue units");
+-    help1("I'm going to assume that 1mu=1pt when they're mixed.");
+-    error();
+-}
+-
+-@ The next routine `|scan_something_internal|' is used to fetch internal
+-numeric quantities like `\.{\\hsize}', and also to handle the `\.{\\the}'
+-when expanding constructions like `\.{\\the\\toks0}' and
+-`\.{\\the\\baselineskip}'. Soon we will be considering the |scan_int|
+-procedure, which calls |scan_something_internal|; on the other hand,
+-|scan_something_internal| also calls |scan_int|, for constructions like
+-`\.{\\catcode\`\\\$}' or `\.{\\fontdimen} \.3 \.{\\ff}'. So we
+-have to declare |scan_int| as a |forward| procedure. A few other
+-procedures are also declared at this point.
+-
+-\TeX\ doesn't know exactly what to expect when
+-|scan_something_internal| begins.  For example, an integer or
+-dimension or glue value could occur immediately after `\.{\\hskip}';
+-and one can even say \.{\\the} with respect to token lists in
+-constructions like `\.{\\xdef\\o\{\\the\\output\}}'.  On the other
+-hand, only integers are allowed after a construction like
+-`\.{\\count}'. To handle the various possibilities,
+-|scan_something_internal| has a |level| parameter, which tells the
+-``highest'' kind of quantity that |scan_something_internal| is allowed
+-to produce. Eight levels are distinguished, namely |int_val|,
+-|attr_val|, |dimen_val|, |glue_val|, |mu_val|, |dir_val|, |ident_val|,
+-and |tok_val|.
+-
+-The output of |scan_something_internal| (and of the other routines
+-|scan_int|, |scan_dimen|, and |scan_glue| below) is put into the global
+-variable |cur_val|, and its level is put into |cur_val_level|. The highest
+-values of |cur_val_level| are special: |mu_val| is used only when
+-|cur_val| points to something in a ``muskip'' register, or to one of the
+-three parameters \.{\\thinmuskip}, \.{\\medmuskip}, \.{\\thickmuskip};
+-|ident_val| is used only when |cur_val| points to a font identifier;
+-|tok_val| is used only when |cur_val| points to |null| or to the reference
+-count of a token list. The last two cases are allowed only when
+-|scan_something_internal| is called with |level=tok_val|.

+-@ The |scan_dimen| routine is similar to |scan_int|, but it sets |cur_val| to
+-a |scaled| value, i.e., an integral number of sp. One of its main tasks
+-is therefore to interpret the abbreviations for various kinds of units and
+-to convert measurements to scaled points.
+-
+-There are three parameters: |mu| is |true| if the finite units must be
+-`\.{mu}', while |mu| is |false| if `\.{mu}' units are disallowed;
+-|inf| is |true| if the infinite units `\.{fil}', `\.{fill}', `\.{filll}'
+-are permitted; and |shortcut| is |true| if |cur_val| already contains
+-an integer and only the units need to be considered.
+-
+-The order of infinity that was found in the case of infinite glue is returned
+-in the global variable |cur_order|.
+-
+-@c
+-int cur_order;                  /* order of infinity found by |scan_dimen| */
+-
+-
+-@ Constructions like `\.{-\'77 pt}' are legal dimensions, so |scan_dimen|
+-may begin with |scan_int|. This explains why it is convenient to use
+-|scan_int| also for the integer part of a decimal fraction.
+-
+-Several branches of |scan_dimen| work with |cur_val| as an integer and
+-with an auxiliary fraction |f|, so that the actual quantity of interest is
+-$|cur_val|+|f|/2^{16}$. At the end of the routine, this ``unpacked''
+-representation is put into the single word |cur_val|, which suddenly
+-switches significance from |integer| to |scaled|.

+-The necessary conversion factors can all be specified exactly as
+-fractions whose numerator and denominator add to 32768 or less.
+-According to the definitions here, $\rm2660\,dd\approx1000.33297\,mm$;
+-this agrees well with the value $\rm1000.333\,mm$ cited by Bosshard
+-\^{Bosshard, Hans Rudolf}
+-in {\sl Technische Grundlagen zur Satzherstellung\/} (Bern, 1980).
+-The Didot point has been newly standardized in 1978;
+-it's now exactly $\rm 1\,nd=0.375\,mm$.
+-Conversion uses the equation $0.375=21681/20320/72.27\cdot25.4$.
+-The new Cicero follows the new Didot point; $\rm 1\,nc=12\,nd$.
+-These would lead to the ratios $21681/20320$ and $65043/5080$,
+-respectively.
+-The closest approximations supported by the algorithm would be
+-$11183/10481$ and $1370/107$.  In order to maintain the

++The bane of portability is the fact that different operating systems treat input
++and output quite differently, perhaps because computer scientists have not given
++sufficient attention to this problem. People have felt somehow that input and
++output are not part of ``real'' programming. Well, it is true that some kinds of
++programming are more fun than others. With existing input/output conventions
++being so diverse and so messy, the only sources of joy in such parts of the code
++are the rare occasions when one can find a way to make the program a little less
++bad than it might have been. We have two choices, either to attack I/O now and
++get it over with, or to postpone I/O until near the end. Neither prospect is very
++attractive, so let's get it over with.
++
++The basic operations we need to do are (1)~inputting and outputting of text, to
++or from a file or the user's terminal; (2)~inputting and outputting of eight-bit
++bytes, to or from a file; (3)~instructing the operating system to initiate
++(``open'') or to terminate (``close'') input or output from a specified file;
++(4)~testing whether the end of an input file has been reached.
++
++\TeX\ needs to deal with two kinds of files. We shall use the term |alpha_file|
++for a file that contains textual data, and the term |byte_file| for a file that
++contains eight-bit binary information. These two types turn out to be the same on
++many computers, but sometimes there is a significant distinction, so we shall be
++careful to distinguish between them. Standard protocols for transferring such
++files from computer to computer, via high-speed networks, are now becoming
++available to more and more communities of users.
++
++The program actually makes use also of a third kind of file, called a
++|word_file|, when dumping and reloading base information for its own
++initialization. We shall define a word file later; but it will be possible for us
++to specify simple operations on word files before they are defined.
++
++We finally did away with |nameoffile| and |namelength|, but the variables have to
++be kept otherwise there will be link errors from |openclose.c| in the web2c
++library

++    values. \TeX's conventions should be efficient, and they should blend nicely
++    with the user's operating environment.
++
++    Input from text files is read one line at a time, using a routine called
++    |lua_input_ln|. This function is defined in terms of global variables called
++    |buffer|, |first|, and |last| that will be described in detail later; for
++    now, it suffices for us to know that |buffer| is an array of |ASCII_code|
++    values, and that |first| and |last| are indices into this array representing
++    the beginning and ending of a line of text.

++
++    The |lua_input_ln| function brings the next line of input from the specified
++    file into available positions of the buffer array and returns the value
++    |true|, unless the file has already been entirely read, in which case it
++    returns |false| and sets |last:=first|. In general, the |ASCII_code| numbers
++    that represent the next line of the file are input into |buffer[first]|,
++    |buffer[first+1]|, \dots, |buffer[last-1]|; and the global variable |last| is
++    set equal to |first| plus the length of the line. Trailing blanks are removed
++    from the line; thus, either |last=first| (in which case the line was entirely
++    blank) or |buffer[last-1]<>" "|.
++
++    An overflow error is given, however, if the normal actions of |lua_input_ln|
++    would make |last>=buf_size|; this is done so that other parts of \TeX\ can
++    safely look at the contents of |buffer[last+1]| without overstepping the
++    bounds of the |buffer| array. Upon entry to |lua_input_ln|, the condition
++    |first<buf_size| will always hold, so that there is always room for an
++    ``empty'' line.
++
++    The variable |max_buf_stack|, which is used to keep track of how large the
++    |buf_size| parameter must be to accommodate the present job, is also kept up
++    to date by |lua_input_ln|.
++
++    If the |bypass_eoln| parameter is |true|, |lua_input_ln| will do a |get|
++    before looking at the first character of the line; this skips over an |eoln|
++    that was in |f^|. The procedure does not do a |get| when it reaches the end
++    of the line; therefore it can be used to acquire input from the user's
++    terminal as well as from ordinary text files.
++
++    Since the inner loop of |lua_input_ln| is part of \TeX's ``inner
++    loop''---each character of input comes in at this place---it is wise to
++    reduce system overhead by making use of special routines that read in an

++
++    We need a special routine to read the first line of \TeX\ input from the
++    user's terminal. This line is different because it is read before we have
++    opened the transcript file; there is sort of a ``chicken and egg'' problem
++    here. If the user types `\.{\\input paper}' on the first line, or if some
++    macro invoked by that line does such an \.{\\input}, the transcript file will
++    be named `\.{paper.log}'; but if no \.{\\input} commands are performed during
++    the first line of terminal input, the transcript file will acquire its
++    default name `\.{texput.log}'. (The transcript file will not contain error
++    messages generated by the first line before the first \.{\\input} command.)
++
++    The first line is special also because it may be read before \TeX\ has input
++    a format file. In such cases, normal error messages cannot yet be given. The
++    following code uses concepts that will be explained later.
++
++    Different systems have different ways to get started. But regardless of what
++    conventions are adopted, the routine that initializes the terminal should
++    satisfy the following specifications:
++
++    \startitemize[n]
++
++        \startitem
++            It should open file |term_in| for input from the terminal. (The file
++            |term_out| will already be open for output to the terminal.)
++        \stopitem
++
++        \startitem
++            If the user has given a command line, this line should be considered
++            the first line of terminal input. Otherwise the user should be
++            prompted with `\.{**}', and the first line of input should be
++            whatever is typed in response.
++        \stopitem
++
++        \startitem
++            The first line of input, which might or might not be a command line,
++            should appear in locations |first| to |last-1| of the |buffer| array.
++        \stopitem
++
++        \startitem
++            The global variable |loc| should be set so that the character to be
++            read next by \TeX\ is in |buffer[loc]|. This character should not be
++            blank, and we should have |loc<last|.
++        \stopitem
++
++    \stopitemize
++
++    It may be necessary to prompt the user several times before a non-blank line
++    comes in. The prompt is `\.{**}' instead of the later `\.*' because the
++    meaning is slightly different: `\.{\\input}' need not be typed immediately
++    after~`\.{**}'.)

++
++    It's time now to fret about file names. Besides the fact that different
++    operating systems treat files in different ways, we must cope with the fact
++    that completely different naming conventions are used by different groups of
++    people. The following programs show what is required for one particular
++    operating system; similar routines for other systems are not difficult to
++    devise.
++
++    \TeX\ assumes that a file name has three parts: the name proper; its
++    ``extension''; and a ``file area'' where it is found in an external file
++    system. The extension of an input file or a write file is assumed to be
++    `\.{.tex}' unless otherwise specified; it is `\.{.log}' on the transcript
++    file that records each run of \TeX; it is `\.{.tfm}' on the font metric files
++    that describe characters in the fonts \TeX\ uses; it is `\.{.dvi}' on the
++    output files that specify typesetting information; and it is `\.{.fmt}' on
++    the format files written by \.{INITEX} to initialize \TeX. The file area can
++    be arbitrary on input files, but files are usually output to the user's
++    current area. If an input file cannot be found on the specified area, \TeX\
++    will look for it on a special system area; this special area is intended for
++    commonly used input files like \.{webmac.tex}.
++
++    Simple uses of \TeX\ refer only to file names that have no explicit extension
++    or area. For example, a person usually says `\.{\\input} \.{paper}' or
++    `\.{\\font\\tenrm} \.= \.{helvetica}' instead of `\.{\\input} \.{paper.new}'
++    or `\.{\\font\\tenrm} \.= \.{<csd.knuth>test}'. Simple file names are best,
++    because they make the \TeX\ source files portable; whenever a file name
++    consists entirely of letters and digits, it should be treated in the same way
++    by all implementations of \TeX. However, users need the ability to refer to
++    other files in their environment, especially when responding to error
++    messages concerning unopenable files; therefore we want to let them use the
++    syntax that appears in their favorite operating system.
++
++    The following procedures don't allow spaces to be part of file names; but
++    some users seem to like names that are spaced-out. System-dependent changes
++    to allow such things should probably be made with reluctance, and only when
++    an entire file name that includes spaces is ``quoted'' somehow.
++
++    Here are the global values that file names will be scanned into.
++
++*/
++
++/*tex name of file just scanned */
++
++str_number cur_name;
++
++/*tex file area just scanned, or \.{""} */

++    The file names we shall deal with have the following structure: If the name
++    contains `\./' or `\.:' (for Amiga only), the file area consists of all

++    area is null. If the remaining file name contains `\..', the file extension
++    consists of all such characters from the last `\..' to the end, otherwise the

+-@ The bane of portability is the fact that different operating systems treat
+-input and output quite differently, perhaps because computer scientists
+-have not given sufficient attention to this problem. People have felt somehow
+-that input and output are not part of ``real'' programming. Well, it is true
+-that some kinds of programming are more fun than others. With existing
+-input/output conventions being so diverse and so messy, the only sources of
+-joy in such parts of the code are the rare occasions when one can find a
+-way to make the program a little less bad than it might have been. We have
+-two choices, either to attack I/O now and get it over with, or to postpone
+-I/O until near the end. Neither prospect is very attractive, so let's
+-get it over with.
+-
+-The basic operations we need to do are (1)~inputting and outputting of
+-text, to or from a file or the user's terminal; (2)~inputting and
+-outputting of eight-bit bytes, to or from a file; (3)~instructing the
+-operating system to initiate (``open'') or to terminate (``close'') input or
+-output from a specified file; (4)~testing whether the end of an input
+-file has been reached.
+-
+-\TeX\ needs to deal with two kinds of files.
+-We shall use the term |alpha_file| for a file that contains textual data,
+-and the term |byte_file| for a file that contains eight-bit binary information.
+-These two types turn out to be the same on many computers, but
+-sometimes there is a significant distinction, so we shall be careful to
+-distinguish between them. Standard protocols for transferring
+-such files from computer to computer, via high-speed networks, are
+-now becoming available to more and more communities of users.
+-
+-The program actually makes use also of a third kind of file, called a
+-|word_file|, when dumping and reloading base information for its own
+-initialization.  We shall define a word file later; but it will be possible
+-for us to specify simple operations on word files before they are defined.
+-
+-@ We finally did away with |nameoffile| and |namelength|, but the variables
+-have to be kept otherwise there will be link errors from |openclose.c| in
+-the web2c library
+-
+-@c
+-char *nameoffile;
+-int namelength;
+-
+-
+-@ When input files are opened via a callback, they will also be read using
+-callbacks. for that purpose, the |open_read_file_callback| returns an
+-integer to uniquely identify a callback table. This id replaces the file
+-point |f| in this case, because the input does not have to be a file
+-in the traditional sense.
+-
+-Signalling this fact is achieved by having two arrays of integers.
+-
+-@c
+-int *input_file_callback_id;
+-int read_file_callback_id[17];
+-
+-@ Handle -output-directory.
+-
+-We assume that it is OK to look here first.  Possibly it
+-would be better to replace lookups in "." with lookups in the
+-|output_directory| followed by "." but to do this requires much more
+-invasive surgery in libkpathsea.

+-@ Binary input and output are done with C's ordinary
+-procedures, so we don't have to make any other special arrangements for
+-binary~I/O. Text output is also easy to do with standard routines.
+-The treatment of text input is more difficult, however, because
+-of the necessary translation to |ASCII_code| values.
+-\TeX's conventions should be efficient, and they should
+-blend nicely with the user's operating environment.
+-
+-Input from text files is read one line at a time, using a routine called
+-|lua_input_ln|. This function is defined in terms of global variables called
+-|buffer|, |first|, and |last| that will be described in detail later; for
+-now, it suffices for us to know that |buffer| is an array of |ASCII_code|
+-values, and that |first| and |last| are indices into this array
+-representing the beginning and ending of a line of text.
+-
+-@c
+-packed_ASCII_code *buffer;      /* lines of characters being read */
+-int first;                      /* the first unused position in |buffer| */
+-int last;                       /* end of the line just input to |buffer| */
+-int max_buf_stack;              /* largest index used in |buffer| */
+-
+-
+-@ The |lua_input_ln| function brings the next line of input from the specified
+-file into available positions of the buffer array and returns the value
+-|true|, unless the file has already been entirely read, in which case it
+-returns |false| and sets |last:=first|.  In general, the |ASCII_code|
+-numbers that represent the next line of the file are input into
+-|buffer[first]|, |buffer[first+1]|, \dots, |buffer[last-1]|; and the
+-global variable |last| is set equal to |first| plus the length of the
+-line. Trailing blanks are removed from the line; thus, either |last=first|
+-(in which case the line was entirely blank) or |buffer[last-1]<>" "|.
+-
+-An overflow error is given, however, if the normal actions of |lua_input_ln|
+-would make |last>=buf_size|; this is done so that other parts of \TeX\
+-can safely look at the contents of |buffer[last+1]| without overstepping
+-the bounds of the |buffer| array. Upon entry to |lua_input_ln|, the condition
+-|first<buf_size| will always hold, so that there is always room for an
+-``empty'' line.
+-
+-The variable |max_buf_stack|, which is used to keep track of how large
+-the |buf_size| parameter must be to accommodate the present job, is
+-also kept up to date by |lua_input_ln|.
+-
+-If the |bypass_eoln| parameter is |true|, |lua_input_ln| will do a |get|
+-before looking at the first character of the line; this skips over
+-an |eoln| that was in |f^|. The procedure does not do a |get| when it
+-reaches the end of the line; therefore it can be used to acquire input
+-from the user's terminal as well as from ordinary text files.
+-
+-Since the inner loop of |lua_input_ln| is part of \TeX's ``inner loop''---each
+-character of input comes in at this place---it is wise to reduce system
+-overhead by making use of special routines that read in an entire array
+-of characters at once, if such routines are available.

+-  user should be prompted with `\.{**}', and the first line of input
+-  should be whatever is typed in response.
+-
+-\textindent{3)}The first line of input, which might or might not be a
+-  command line, should appear in locations |first| to |last-1| of the

+-@ It's time now to fret about file names.  Besides the fact that different

+-fact that completely different naming conventions are used by different
+-groups of people. The following programs show what is required for one
+-particular operating system; similar routines for other systems are not
+-difficult to devise.
+-@^fingers@>
+-@^system dependencies@>
+-
+-\TeX\ assumes that a file name has three parts: the name proper; its
+-``extension''; and a ``file area'' where it is found in an external file
+-system.  The extension of an input file or a write file is assumed to be
+-`\.{.tex}' unless otherwise specified; it is `\.{.log}' on the
+-transcript file that records each run of \TeX; it is `\.{.tfm}' on the font
+-metric files that describe characters in the fonts \TeX\ uses; it is
+-`\.{.dvi}' on the output files that specify typesetting information; and it
+-is `\.{.fmt}' on the format files written by \.{INITEX} to initialize \TeX.
+-The file area can be arbitrary on input files, but files are usually
+-output to the user's current area.  If an input file cannot be
+-found on the specified area, \TeX\ will look for it on a special system
+-area; this special area is intended for commonly used input files like
+-\.{webmac.tex}.
+-
+-Simple uses of \TeX\ refer only to file names that have no explicit
+-extension or area. For example, a person usually says `\.{\\input} \.{paper}'
+-or `\.{\\font\\tenrm} \.= \.{helvetica}' instead of `\.{\\input}
+-\.{paper.new}' or `\.{\\font\\tenrm} \.= \.{<csd.knuth>test}'. Simple file
+-names are best, because they make the \TeX\ source files portable;
+-whenever a file name consists entirely of letters and digits, it should be
+-treated in the same way by all implementations of \TeX. However, users
+-need the ability to refer to other files in their environment, especially
+-when responding to error messages concerning unopenable files; therefore
+-we want to let them use the syntax that appears in their favorite
+-operating system.
+-
+-The following procedures don't allow spaces to be part of
+-file names; but some users seem to like names that are spaced-out.
+-System-dependent changes to allow such things should probably
+-be made with reluctance, and only when an entire file name that
+-includes spaces is ``quoted'' somehow.
+-
+-Here are the global values that file names will be scanned into.
+-
+-@c
+-str_number cur_name;            /* name of file just scanned */
+-str_number cur_area;            /* file area just scanned, or \.{""} */
+-str_number cur_ext;             /* file extension just scanned, or \.{""} */
+-
+-
+-@ The file names we shall deal with have the
+-following structure:  If the name contains `\./' or `\.:'
+-(for Amiga only), the file area
+-consists of all characters up to and including the final such character;
+-otherwise the file area is null.  If the remaining file name contains
+-`\..', the file extension consists of all such characters from the last
+-`\..' to the end, otherwise the file extension is null.
+-
+-We can scan such file names easily by using two global variables that keep track
+-of the occurrences of area and extension delimiters:
+-
+-@c
+-pool_pointer area_delimiter;    /* the most recent `\./', if any */
+-pool_pointer ext_delimiter;     /* the relevant `\..', if any */
+-
+-
+-@ Input files that can't be found in the user's area may appear in a standard
+-system area called |TEX_area|. Font metric files whose areas are not given
+-explicitly are assumed to appear in a standard system area called
+-|TEX_font_area|.  $\Omega$'s compiled translation process files whose areas
+-are not given explicitly are assumed to appear in a standard system area.
+-These system area names will, of course, vary from place to place.

+-@ When \TeX\ reads a formula that is enclosed between \.\$'s, it constructs an
+-{\sl mlist}, which is essentially a tree structure representing that
+-formula.  An mlist is a linear sequence of items, but we can regard it as
+-a tree structure because mlists can appear within mlists. For example, many
+-of the entries can be subscripted or superscripted, and such ``scripts''
+-are mlists in their own right.
+-
+-An entire formula is parsed into such a tree before any of the actual
+-typesetting is done, because the current style of type is usually not
+-known until the formula has been fully scanned. For example, when the
+-formula `\.{\$a+b \\over c+d\$}' is being read, there is no way to tell
+-that `\.{a+b}' will be in script size until `\.{\\over}' has appeared.
+-
+-During the scanning process, each element of the mlist being built is
+-classified as a relation, a binary operator, an open parenthesis, etc.,
+-or as a construct like `\.{\\sqrt}' that must be built up. This classification
+-appears in the mlist data structure.
+-
+-After a formula has been fully scanned, the mlist is converted to an hlist
+-so that it can be incorporated into the surrounding text. This conversion is
+-controlled by a recursive procedure that decides all of the appropriate
+-styles by a ``top-down'' process starting at the outermost level and working
+-in towards the subformulas. The formula is ultimately pasted together using
+-combinations of horizontal and vertical boxes, with glue and penalty nodes
+-inserted as necessary.
+-
+-An mlist is represented internally as a linked list consisting chiefly
+-of ``noads'' (pronounced ``no-adds''), to distinguish them from the somewhat
+-similar ``nodes'' in hlists and vlists. Certain kinds of ordinary nodes are
+-allowed to appear in mlists together with the noads; \TeX\ tells the difference
+-by means of the |type| field, since a noad's |type| is always greater than
+-that of a node. An mlist does not contain character nodes, hlist nodes, vlist
+-nodes, math nodes or unset nodes; in particular, each mlist item appears in the
+-variable-size part of |mem|, so the |type| field is always present.
+-
+-Each noad is five or more words long. The first word contains the
+-|type| and |subtype| and |link| fields that are already so familiar to
+-us; the second contains the attribute list pointer, and the third,
+-fourth an fifth words are called the noad's |nucleus|, |subscr|, and
+-|supscr| fields. (This use of a combined attribute list is temporary.
+-Eventually, each of fields need their own list)
+-
+-Consider, for example, the simple formula `\.{\$x\^2\$}', which would be
+-parsed into an mlist containing a single element called an |ord_noad|.
+-The |nucleus| of this noad is a representation of `\.x', the |subscr| is
+-empty, and the |supscr| is a representation of `\.2'.
+-
+-The |nucleus|, |subscr|, and |supscr| fields are further broken into
+-subfields. If |p| points to a noad, and if |q| is one of its principal
+-fields (e.g., |q=subscr(p)|), |q=null| indicates a field with no value (the
+-corresponding attribute of noad |p| is not present). Otherwise, there are
+-several possibilities for the subfields, depending on the |type| of |q|.
+-
+-\yskip\hang|type(q)=math_char_node| means that |math_fam(q)| refers to one of
+-the sixteen font families, and |character(q)| is the number of a character
+-within a font of that family, as in a character node.
+-
+-\yskip\hang|type(q)=math_text_char_node| is similar, but the character is
+-unsubscripted and unsuperscripted and it is followed immediately by another
+-character from the same font. (This |type| setting appears only
+-briefly during the processing; it is used to suppress unwanted italic
+-corrections.)
+-
+-\yskip\hang|type(q)=sub_box_node| means that |math_list(q)| points to a box
+-node (either an |hlist_node| or a |vlist_node|) that should be used as the
+-value of the field.  The |shift_amount| in the subsidiary box node is the
+-amount by which that box will be shifted downward.
+-
+-\yskip\hang|type(q)=sub_mlist_node| means that |math_list(q)| points to
+-an mlist; the mlist must be converted to an hlist in order to obtain
+-the value of this field.
+-
+-\yskip\noindent In the latter case, we might have |math_list(q)=null|. This
+-is not the same as |q=null|; for example, `\.{\$P\_\{\}\$}'
+-and `\.{\$P\$}' produce different results (the former will not have the
+-``italic correction'' added to the width of |P|, but the ``script skip''
+-will be added).

+-A noad of type |ord_noad|, |op_noad|, \dots, |inner_noad| usually

+-Delimiter fields have four subfields

+-
+-A |fraction_noad| is actually quite different from all other noads.
+-It has |thickness|, |denominator|, and |numerator| fields instead of

++    A noad of type |ord_noad|, |op_noad|, \dots, |inner_noad| usually has a
++    |subtype=normal|. The only exception is that an |op_noad| might have
++    |subtype=limits| or |no_limits|, if the normal positioning of limits has been
++    overridden for this operator.
++
++    A |radical_noad| also has a |left_delimiter| field, which usually represents
++    a square root sign.
++
++    A |fraction_noad| has a |right_delimiter| field as well as a
++    |left_delimiter|.
++
++    Delimiter fields have four subfields called |small_fam|, |small_char|,
++    |large_fam|, |large_char|. These subfields represent variable-size delimiters
++    by giving the ``small'' and ``large'' starting characters, as explained in
++    Chapter~17 of {\sl The \TeX book}.
++
++    A |fraction_noad| is actually quite different from all other noads. It has
++    |thickness|, |denominator|, and |numerator| fields instead of |nucleus|,
++    |subscr|, and |supscr|. The |thickness| is a scaled value that tells how
++    thick to make a fraction rule; however, the special value |default_code| is
++    used to stand for the |default_rule_thickness| of the current size. The
++    |numerator| and |denominator| point to mlists that define a fraction; we
++    always have $$\hbox{|type(numerator)=type(denominator)=sub_mlist|}.$$ The
++    |left_delimiter| and |right_delimiter| fields specify delimiters that will be
++    placed at the left and right of the fraction. In this way, a |fraction_noad|
++    is able to represent all of \TeX's operators \.{\\over}, \.{\\atop},
++    \.{\\above}, \.{\\overwithdelims}, \.{\\atopwithdelims}, and
++    \.{\\abovewithdelims}.
++
++    The |new_noad| function creates an |ord_noad| that is completely null

++    This module started out using NDEBUG to trigger checking invalid node usage,

++    point that code was always enabled so it is now always on but still can be
++    recognized as additional code. And as the performance hit is close to zero so
++    disabling makes no sense, not even to make it configureable. There is a
++    little more memory used but that is neglectable compared to other memory

++
++    When we copy a node list, there are several possibilities: we do the same as
++    a new node, we copy the entry to the table in properties (a reference), we do
++    a deep copy of a table in the properties, we create a new table and give it
++    the original one as a metatable. After some experiments (that also included
++    timing) with these scenarios I decided that a deep copy made no sense, nor
++    did nilling. In the end both the shallow copy and the metatable variant were
++    both ok, although the second ons is slower. The most important aspect to keep
++    in mind is that references to other nodes in properties no longer can be
++    valid for that copy. We could use two tables (one unique and one shared) or
++    metatables but that only complicates matters.
++
++    When defining a new node, we could already allocate a table but it is rather
++    easy to do that at the lua end e.g. using a metatable __index method. That
++    way it is under macro package control.
++
++    When deleting a node, we could keep the slot (e.g. setting it to false) but
++    it could make memory consumption raise unneeded when we have temporary large
++    node lists and after that only small lists.
++
++    So, in the end this is what we ended up with. For the record, I also
++    experimented with the following:
++
++    \startitemize
++
++        \startitem
++            Copy attributes to the properties so that we have fast access at the
++            lua end: in the end the overhead is not compensated by speed and
++            convenience, in fact, attributes are not that slow when it comes to
++            accessing them.
++        \stopitem
++
++        \startitem
++            A bitset in the node but again the gain compared to attributes is
++            neglectable and it also demands a pretty string agreement over what
++            bit represents what, and this is unlikely to succeed in the tex
++            community (I could use it for font handling, which is cross package,
++            but decided that it doesn't pay off.
++        \stopitem
++
++    \stopitemize
++
++    In case one wonders why properties make sense then, well, it is not so much
++    speed that we gain, but more convenience: storing all kind of (temporary)
++    data in attributes is no fun and this mechanism makes sure that properties
++    are cleaned up when a node is freed. Also, the advantage of a more or less
++    global properties table is that we stay at the lua end. An alternative is to
++    store a reference in the node itself but that is complicated by the fact that
++    the register has some limitations (no numeric keys) and we also don't want to
++    mess with it too much.

++
++    From the computer's standpoint, \TeX's chief mission is to create horizontal
++    and vertical lists. We shall now investigate how the elements of these lists
++    are represented internally as nodes in the dynamic memory.
++
++    A horizontal or vertical list is linked together by |link| fields in the
++    first word of each node. Individual nodes represent boxes, glue, penalties,
++    or special things like discretionary hyphens; because of this variety, some
++    nodes are longer than others, and we must distinguish different kinds of
++    nodes. We do this by putting a `|type|' field in the first word, together
++    with the link and an optional `|subtype|'.
++
++    Character nodes appear only in horizontal lists, never in vertical lists.
++
++    An |hlist_node| stands for a box that was made from a horizontal list. Each
++    |hlist_node| is seven words long, and contains the following fields (in
++    addition to the mandatory |type| and |link|, which we shall not mention
++    explicitly when discussing the other node types): The |height| and |width|
++    and |depth| are scaled integers denoting the dimensions of the box. There is
++    also a |shift_amount| field, a scaled integer indicating how much this box
++    should be lowered (if it appears in a horizontal list), or how much it should
++    be moved to the right (if it appears in a vertical list). There is a
++    |list_ptr| field, which points to the beginning of the list from which this
++    box was fabricated; if |list_ptr| is |null|, the box is empty. Finally, there
++    are three fields that represent the setting of the glue: |glue_set(p)| is a
++    word of type |glue_ratio| that represents the proportionality constant for
++    glue setting; |glue_sign(p)| is |stretching| or |shrinking| or |normal|
++    depending on whether or not the glue should stretch or shrink or remain
++    rigid; and |glue_order(p)| specifies the order of infinity to which glue
++    setting applies (|normal|, |sfi|, |fil|, |fill|, or |filll|). The |subtype|
++    field is not used.
++
++    The |new_null_box| function returns a pointer to an |hlist_node| in which all
++    subfields have the values corresponding to `\.{\\hbox\{\}}'. The |subtype|
++    field is set to |min_quarterword|, since that's the desired |span_count|
++    value if this |hlist_node| is changed to an |unset_node|.

++    indicates the corresponding box number. For example, `\.{\\insert 250}' leads
++    to an |ins_node| whose |subtype| is |250+min_quarterword|. The |height| field
++    of an |ins_node| is slightly misnamed; it actually holds the natural height
++    plus depth of the vertical list being inserted. The |depth| field holds the
++    |split_max_depth| to be used in case this insertion is split, and the
++    |split_top_ptr| points to the corresponding |split_top_skip|. The
++    |float_cost| field holds the |floating_penalty| that will be used if this
++    insertion floats to a subsequent page after a split insertion of the same
++    class. There is one more field, the |ins_ptr|, which points to the beginning
++    of the vlist for the insertion.
++
++    A |mark_node| has a |mark_ptr| field that points to the reference count of a
++    token list that contains the user's \.{\\mark} text. In addition there is a
++    |mark_class| field that contains the mark class.
++
++    An |adjust_node|, which occurs only in horizontal lists, specifies material
++    that will be moved out into the surrounding vertical list; i.e., it is used
++    to implement \TeX's `\.{\\vadjust}' operation. The |adjust_ptr| field points
++    to the vlist containing this material.
++
++    A |glyph_node|, which occurs only in horizontal lists, specifies a glyph in a
++    particular font, along with its attribute list. Older versions of \TeX\ could
++    use token memory for characters, because the font,char combination would fit
++    in a single word (both values were required to be strictly less than
++    $2^{16}$). In LuaTeX, room is needed for characters that are larger than
++    that, as well as a pointer to a potential attribute list, and the two
++    displacement values.
++
++    In turn, that made the node so large that it made sense to merge ligature
++    glyphs as well, as that requires only one extra pointer. A few extra classes
++    of glyph nodes will be introduced later. The unification of all those types
++    makes it easier to manipulate lists of glyphs. The subtype differentiates
++    various glyph kinds.
++
++    First, here is a function that returns a pointer to a glyph node for a given
++    glyph in a given font. If that glyph doesn't exist, |null| is returned
++    instead. Nodes of this subtype are directly created only for accents and

++    from |mlist| to |hlist|).

++    discussion of extensions until the end of this program.

++
++    \TeX\ makes use of the fact that |hlist_node|, |vlist_node|, |rule_node|,
++    |ins_node|, |mark_node|, |adjust_node|, |disc_node|, |whatsit_node|, and
++    |math_node| are at the low end of the type codes, by permitting a break at
++    glue in a list if and only if the |type| of the previous node is less than
++    |math_node|. Furthermore, a node is discarded after a break if its type is
++    |math_node| or~more.
++
++    A |glue_node| represents glue in a list. However, it is really only a pointer
++    to a separate glue specification, since \TeX\ makes use of the fact that many
++    essentially identical nodes of glue are usually present. If |p| points to a
++    |glue_node|, |glue_ptr(p)| points to another packet of words that specify the
++    stretch and shrink components, etc.
++
++    Glue nodes also serve to represent leaders; the |subtype| is used to
++    distinguish between ordinary glue (which is called |normal|) and the three
++    kinds of leaders (which are called |a_leaders|, |c_leaders|, and
++    |x_leaders|). The |leader_ptr| field points to a rule node or to a box node
++    containing the leaders; it is set to |null| in ordinary glue nodes.
++
++    Many kinds of glue are computed from \TeX's ``skip'' parameters, and it is
++    helpful to know which parameter has led to a particular glue node. Therefore
++    the |subtype| is set to indicate the source of glue, whenever it originated
++    as a parameter. We will be defining symbolic names for the parameter numbers
++    later (e.g., |line_skip_code=0|, |baseline_skip_code=1|, etc.); it suffices
++    for now to say that the |subtype| of parametric glue will be the same as the
++    parameter number, plus~one.
++
++    In math formulas there are two more possibilities for the |subtype| in a glue
++    node: |mu_glue| denotes an \.{\\mskip} (where the units are scaled \.{mu}
++    instead of scaled \.{pt}); and |cond_math_glue| denotes the `\.{\\nonscript}'
++    feature that cancels the glue node immediately following if it appears in a
++    subscript.
++
++    A glue specification has a halfword reference count in its first word,
++    representing |null| plus the number of glue nodes that point to it (less
++    one). Note that the reference count appears in the same position as the
++    |link| field in list nodes; this is the field that is initialized to |null|
++    when a node is allocated, and it is also the field that is flagged by
++    |empty_flag| in empty nodes.
++
++    Glue specifications also contain three |scaled| fields, for the |width|,
++    |stretch|, and |shrink| dimensions. Finally, there are two one-byte fields
++    called |stretch_order| and |shrink_order|; these contain the orders of

++    You might think that we have introduced enough node types by now. Well,
++    almost, but there is one more: An |unset_node| has nearly the same format as
++    an |hlist_node| or |vlist_node|; it is used for entries in \.{\\halign} or
++    \.{\\valign} that are not yet in their final form, since the box dimensions
++    are their ``natural'' sizes before any glue adjustment has been made. The
++    |glue_set| word is not present; instead, we have a |glue_stretch| field,
++    which contains the total stretch of order |glue_order| that is present in the
++    hlist or vlist being boxed. Similarly, the |shift_amount| field is replaced
++    by a |glue_shrink| field, containing the total shrink of order |glue_sign|
++    that is present. The |subtype| field is called |span_count|; an unset box
++    typically contains the data for |qo(span_count)+1| columns. Unset nodes will
++    be changed to box nodes when alignment is completed.
++
++    In fact, there are still more types coming. When we get to math formula
++    processing we will see that a |style_node| has |type=14|; and a number of
++    larger type codes will also be defined, for use in math mode only.
++
++    Warning: If any changes are made to these data structure layouts, such as
++    changing any of the node sizes or even reordering the words of nodes, the
++    |copy_node_list| procedure and the memory initialization code below may have
++    to be changed. Such potentially dangerous parts of the program are listed in
++    the index under `data structure assumptions'. However, other references to
++    the nodes are made symbolically in terms of the \.{WEB} macro definitions
++    above, so that format changes will leave \TeX's other algorithms intact.

+-This module started out using NDEBUG to trigger checking invalid node usage,
+-something that is needed because users can mess up nodes in Lua. At some point
+-that code was always enabled so it is now always on but still can be recognized
+-as additional code. And as the performance hit is close to zero so disabling
+-makes no sense, not even to make it configureable. There is a little more memory
+-used but that is neglectable compared to other memory usage.

+-When we copy a node list, there are several possibilities: we do the same as a new node,
+-we copy the entry to the table in properties (a reference), we do a deep copy of a table
+-in the properties, we create a new table and give it the original one as a metatable.
+-After some experiments (that also included timing) with these scenarios I decided that a
+-deep copy made no sense, nor did nilling. In the end both the shallow copy and the metatable
+-variant were both ok, although the second ons is slower. The most important aspect to keep
+-in mind is that references to other nodes in properties no longer can be valid for that
+-copy. We could use two tables (one unique and one shared) or metatables but that only
+-complicates matters.
+-
+-When defining a new node, we could already allocate a table but it is rather easy to do
+-that at the lua end e.g. using a metatable __index method. That way it is under macro
+-package control.
+-
+-When deleting a node, we could keep the slot (e.g. setting it to false) but it could make
+-memory consumption raise unneeded when we have temporary large node lists and after that
+-only small lists.
+-
+-So, in the end this is what we ended up with. For the record, I also experimented with the
+-following:
+-
+-- copy attributes to the properties so that we have fast access at the lua end: in the end
+-  the overhead is not compensated by speed and convenience, in fact, attributes are not
+-  that slow when it comes to accessing them
+-
+-- a bitset in the node but again the gain compared to attributes is neglectable and it also
+-  demands a pretty string agreement over what bit represents what, and this is unlikely to
+-  succeed in the tex community (I could use it for font handling, which is cross package,
+-  but decided that it doesn't pay off
+-
+-In case one wonders why properties make sense then, well, it is not so much speed that we
+-gain, but more convenience: storing all kind of (temporary) data in attributes is no fun and
+-this mechanism makes sure that properties are cleaned up when a node is freed. Also, the
+-advantage of a more or less global properties table is that we stay at the lua end. An
+-alternative is to store a reference in the node itself but that is complicated by the fact
+-that the register has some limitations (no numeric keys) and we also don't want to mess with
+-it too much.

+-@  Now we are ready for |show_node_list| itself. This procedure has been
+-  written to be ``extra robust'' in the sense that it should not crash or get
+-  into a loop even if the data structures have been messed up by bugs in
+-  the rest of the program. You can safely call its parent routine
+-  |show_box(p)| for arbitrary values of |p| when you are debugging \TeX.
+-  However, in the presence of bad data, the procedure may
+-  fetch a |memory_word| whose variant is different from the way it was stored;
+-  for example, it might try to read |mem[p].hh| when |mem[p]|
+-  contains a scaled integer, if |p| is a pointer that has been
+-  clobbered or chosen at random.

+-penalties, or special things like discretionary hyphens; because of this
+-variety, some nodes are longer than others, and we must distinguish different
+-kinds of nodes. We do this by putting a `|type|' field in the first word,
+-together with the link and an optional `|subtype|'.
+-
+-@ Character nodes appear only in horizontal lists, never in vertical lists.
+-
+-An |hlist_node| stands for a box that was made from a horizontal list.
+-Each |hlist_node| is seven words long, and contains the following fields
+-(in addition to the mandatory |type| and |link|, which we shall not
+-mention explicitly when discussing the other node types): The |height| and
+-|width| and |depth| are scaled integers denoting the dimensions of the
+-box.  There is also a |shift_amount| field, a scaled integer indicating
+-how much this box should be lowered (if it appears in a horizontal list),
+-or how much it should be moved to the right (if it appears in a vertical
+-list). There is a |list_ptr| field, which points to the beginning of the
+-list from which this box was fabricated; if |list_ptr| is |null|, the box
+-is empty. Finally, there are three fields that represent the setting of
+-the glue:  |glue_set(p)| is a word of type |glue_ratio| that represents
+-the proportionality constant for glue setting; |glue_sign(p)| is
+-|stretching| or |shrinking| or |normal| depending on whether or not the
+-glue should stretch or shrink or remain rigid; and |glue_order(p)|
+-specifies the order of infinity to which glue setting applies (|normal|,
+-|sfi|, |fil|, |fill|, or |filll|). The |subtype| field is not used.
+-
+-@ The |new_null_box| function returns a pointer to an |hlist_node| in
+-which all subfields have the values corresponding to `\.{\\hbox\{\}}'.
+-The |subtype| field is set to |min_quarterword|, since that's the desired
+-|span_count| value if this |hlist_node| is changed to an |unset_node|.
+-
+-@c
+-halfword new_null_box(void)
+-{                               /* creates a new box node */
+-    halfword p = new_node(hlist_node, min_quarterword);
+-    box_dir(p) = text_direction_par;
+-    return p;
+-}
+-
+-@ A |vlist_node| is like an |hlist_node| in all respects except that it
+-contains a vertical list.
+-
+-@ A |rule_node| stands for a solid black rectangle; it has |width|,
+-|depth|, and |height| fields just as in an |hlist_node|. However, if
+-any of these dimensions is $-2^{30}$, the actual value will be determined
+-by running the rule up to the boundary of the innermost enclosing box.
+-This is called a ``running dimension.'' The |width| is never running in
+-an hlist; the |height| and |depth| are never running in a~vlist.
+-
+-@ A new rule node is delivered by the |new_rule| function. It
+-makes all the dimensions ``running,'' so you have to change the
+-ones that are not allowed to run.
+-
+-@c
+-halfword new_rule(int s)
+-{
+-    halfword p = new_node(rule_node,s);
+-    return p;
+-}
+-
+-@ Insertions are represented by |ins_node| records, where the |subtype|
+-indicates the corresponding box number. For example, `\.{\\insert 250}'
+-leads to an |ins_node| whose |subtype| is |250+min_quarterword|.
+-The |height| field of an |ins_node| is slightly misnamed; it actually holds
+-the natural height plus depth of the vertical list being inserted.
+-The |depth| field holds the |split_max_depth| to be used in case this
+-insertion is split, and the |split_top_ptr| points to the corresponding
+-|split_top_skip|. The |float_cost| field holds the |floating_penalty| that
+-will be used if this insertion floats to a subsequent page after a
+-split insertion of the same class.  There is one more field, the
+-|ins_ptr|, which points to the beginning of the vlist for the insertion.
+-
+-@ A |mark_node| has a |mark_ptr| field that points to the reference count
+-of a token list that contains the user's \.{\\mark} text.
+-In addition there is a |mark_class| field that contains the mark class.
+-
+-@ An |adjust_node|, which occurs only in horizontal lists,
+-specifies material that will be moved out into the surrounding
+-vertical list; i.e., it is used to implement \TeX's `\.{\\vadjust}'
+-operation.  The |adjust_ptr| field points to the vlist containing this
+-material.
+-
+-@ A |glyph_node|, which occurs only in horizontal lists, specifies a
+-glyph in a particular font, along with its attribute list. Older
+-versions of \TeX\ could use token memory for characters, because the
+-font,char combination would fit in a single word (both values were
+-required to be strictly less than $2^{16}$). In LuaTeX, room is
+-needed for characters that are larger than that, as well as a pointer
+-to a potential attribute list, and the two displacement values.
+-
+-In turn, that made the node so large that it made sense to merge
+-ligature glyphs as well, as that requires only one extra pointer.  A
+-few extra classes of glyph nodes will be introduced later.  The
+-unification of all those types makes it easier to manipulate lists of
+-glyphs. The subtype differentiates various glyph kinds.
+-
+-First, here is a function that returns a pointer to a glyph node for a given
+-glyph in a given font. If that glyph doesn't exist, |null| is returned
+-instead.  Nodes of this subtype are directly created only for accents
+-and their base (through |make_accent|), and math nucleus items (in the
+-conversion from |mlist| to |hlist|).
+-
+-@c
+-halfword new_glyph(int f, int c)
+-{
+-    halfword p = null;          /* the new node */
+-    if ((f == 0) || (char_exists(f, c))) {
+-        p = new_glyph_node();
+-        set_to_glyph(p);
+-        font(p) = f;
+-        character(p) = c;
+-    }
+-    return p;
+-}
+-
+-@ A subset of the glyphs nodes represent ligatures: characters
+-fabricated from the interaction of two or more actual characters.  The
+-characters that generated the ligature have not been forgotten, since
+-they are needed for diagnostic messages; the |lig_ptr| field points to
+-a linked list of character nodes for all original characters that have
+-been deleted. (This list might be empty if the characters that
+-generated the ligature were retained in other nodes.)
+-
+-The |subtype| field of these |glyph_node|s is 1, plus 2 and/or 1 if
+-the original source of the ligature included implicit left and/or
+-right boundaries. These nodes are created by the C function |new_ligkern|.
+-
+-A third general type of glyphs could be called a character, as it
+-only appears in lists that are not yet processed by the ligaturing and
+-kerning steps of the program.
+-
+-|main_control| inserts these, and they are later converted to
+-|subtype_normal| by |new_ligkern|.
+-
+-@c
+-quarterword norm_min(int h)
+-{
+-    if (h <= 0)
+-        return 1;
+-    else if (h >= 255)
+-        return 255;
+-    else
+-        return (quarterword) h;
+-}
+-
+-halfword new_char(int f, int c)
+-{
+-    halfword p;                 /* the new node */
+-    p = new_glyph_node();
+-    set_to_character(p);
+-    font(p) = f;
+-    character(p) = c;
+-    lang_data(p) = make_lang_data(uc_hyph_par, cur_lang_par, left_hyphen_min_par, right_hyphen_min_par);
+-    return p;
+-}
+-
+-@ Left and right ghost glyph nodes are the result of \.{\\leftghost}
+-and \.{\\rightghost}, respectively. They are going to be removed by
+-|new_ligkern|, at the end of which they are no longer needed.
+-
+-@ Here are a few handy helpers used by the list output routines.
+-
+-@c
+-scaled glyph_width(halfword p)
+-{
+-    scaled w = char_width(font(p), character(p));
+-    return w;
+-}
+-
+-scaled glyph_height(halfword p)
+-{
+-    scaled w = char_height(font(p), character(p)) + y_displace(p);
+-    if (w < 0)
+-        w = 0;
+-    return w;
+-}
+-
+-scaled glyph_depth(halfword p)
+-{
+-    scaled w = char_depth(font(p), character(p));
+-    if (y_displace(p) > 0)
+-        w = w - y_displace(p);
+-    if (w < 0)
+-        w = 0;
+-    return w;
+-}
+-
+-@ A |disc_node|, which occurs only in horizontal lists, specifies a
+-``dis\-cretion\-ary'' line break. If such a break occurs at node |p|, the text
+-that starts at |pre_break(p)| will precede the break, the text that starts at
+-|post_break(p)| will follow the break, and text that appears in
+-|no_break(p)| nodes will be ignored. For example, an ordinary
+-discretionary hyphen, indicated by `\.{\\-}', yields a |disc_node| with
+-|pre_break| pointing to a |char_node| containing a hyphen, |post_break=null|,
+-and |no_break=null|.
+-
+-{TODO: Knuth said: All three of the discretionary texts must be lists
+-that consist entirely of character, kern, box and rule nodes.}
+-
+-If |subtype(p)=automatic_disc|, the |ex_hyphen_penalty| will be charged for this
+-break.  Otherwise the |hyphen_penalty| will be charged.  The texts will
+-actually be substituted into the list by the line-breaking algorithm if it
+-decides to make the break, and the discretionary node will disappear at
+-that time; thus, the output routine sees only discretionaries that were
+-not chosen.
+-
+-@c
+-halfword new_disc(void)
+-{                               /* creates an empty |disc_node| */
+-    halfword p = new_node(disc_node, 0);
+-    disc_penalty(p) = hyphen_penalty_par;
+-    return p;
+-}
+-
+-@ A |whatsit_node| is a wild card reserved for extensions to \TeX. The
+-|subtype| field in its first word says what `\\{whatsit}' it is, and
+-implicitly determines the node size (which must be 2 or more) and the
+-format of the remaining words. When a |whatsit_node| is encountered
+-in a list, special actions are invoked; knowledgeable people who are
+-careful not to mess up the rest of \TeX\ are able to make \TeX\ do new
+-things by adding code at the end of the program. For example, there
+-might be a `\TeX nicolor' extension to specify different colors of ink,
+-@^extensions to \TeX@>
+-and the whatsit node might contain the desired parameters.
+-
+-The present implementation of \TeX\ treats the features associated with
+-`\.{\\write}' and `\.{\\special}' as if they were extensions, in order to
+-illustrate how such routines might be coded. We shall defer further
+-discussion of extensions until the end of this program.
+-
+-@ A |math_node|, which occurs only in horizontal lists, appears before and
+-after mathematical formulas. The |subtype| field is |before| before the
+-formula and |after| after it. There is a |surround| field, which represents
+-the amount of surrounding space inserted by \.{\\mathsurround}.
+-
+-@c
+-halfword new_math(scaled w, int s)
+-{
+-    halfword p = new_node(math_node, s);
+-    surround(p) = w;
+-    return p;
+-}
+-
+-@ \TeX\ makes use of the fact that |hlist_node|, |vlist_node|,
+-|rule_node|, |ins_node|, |mark_node|, |adjust_node|,
+-|disc_node|, |whatsit_node|, and |math_node| are at the low end of the
+-type codes, by permitting a break at glue in a list if and only if the
+-|type| of the previous node is less than |math_node|. Furthermore, a
+-node is discarded after a break if its type is |math_node| or~more.
+-
+-@ A |glue_node| represents glue in a list. However, it is really only
+-a pointer to a separate glue specification, since \TeX\ makes use of the
+-fact that many essentially identical nodes of glue are usually present.
+-If |p| points to a |glue_node|, |glue_ptr(p)| points to
+-another packet of words that specify the stretch and shrink components, etc.
+-
+-Glue nodes also serve to represent leaders; the |subtype| is used to
+-distinguish between ordinary glue (which is called |normal|) and the three
+-kinds of leaders (which are called |a_leaders|, |c_leaders|, and |x_leaders|).
+-The |leader_ptr| field points to a rule node or to a box node containing the
+-leaders; it is set to |null| in ordinary glue nodes.
+-
+-Many kinds of glue are computed from \TeX's ``skip'' parameters, and
+-it is helpful to know which parameter has led to a particular glue node.
+-Therefore the |subtype| is set to indicate the source of glue, whenever
+-it originated as a parameter. We will be defining symbolic names for the
+-parameter numbers later (e.g., |line_skip_code=0|, |baseline_skip_code=1|,
+-etc.); it suffices for now to say that the |subtype| of parametric glue
+-will be the same as the parameter number, plus~one.
+-
+-@ In math formulas there are two more possibilities for the |subtype| in a
+-glue node: |mu_glue| denotes an \.{\\mskip} (where the units are scaled \.{mu}
+-instead of scaled \.{pt}); and |cond_math_glue| denotes the `\.{\\nonscript}'
+-feature that cancels the glue node immediately following if it appears
+-in a subscript.
+-
+-@ A glue specification has a halfword reference count in its first word,
+-@^reference counts@>
+-representing |null| plus the number of glue nodes that point to it (less one).
+-Note that the reference count appears in the same position as
+-the |link| field in list nodes; this is the field that is initialized
+-to |null| when a node is allocated, and it is also the field that is flagged
+-by |empty_flag| in empty nodes.
+-
+-Glue specifications also contain three |scaled| fields, for the |width|,
+-|stretch|, and |shrink| dimensions. Finally, there are two one-byte
+-fields called |stretch_order| and |shrink_order|; these contain the
+-orders of infinity (|normal|, |sfi|, |fil|, |fill|, or |filll|)
+-corresponding to the stretch and shrink values.
+-
+-@ Here is a function that returns a pointer to a copy of a glue spec.
+-The reference count in the copy is |null|, because there is assumed
+-to be exactly one reference to the new specification.
+-
+-@c
+-halfword new_spec(halfword q) /* safeguard for copying a glue node */
+-{
+-    if (q == null) {
+-        return copy_node(zero_glue);
+-    } else if (type(q) == glue_spec_node) {
+-        return copy_node(q);
+-    } else if (type(q) == glue_node) {
+-        halfword p = copy_node(zero_glue);
+-        width(p) = width(q);
+-        stretch(p) = stretch(q);
+-        shrink(p) = shrink(q);
+-        stretch_order(p) = stretch_order(q);
+-        shrink_order(p) = shrink_order(q);
+-        return p;
+-    } else {
+-        /* alternatively we can issue a warning */
+-        return copy_node(zero_glue);
+-    }
+-}
+-
+-@ And here's a function that creates a glue node for a given parameter
+-identified by its code number; for example,
+-|new_param_glue(line_skip_code)| returns a pointer to a glue node for the
+-current \.{\\lineskip}.
+-
+-@c
+-halfword new_param_glue(int n)
+-{
+-    halfword p = new_node(glue_node, n + 1);
+-    halfword q = glue_par(n);
+-    width(p) = width(q);
+-    stretch(p) = stretch(q);
+-    shrink(p) = shrink(q);
+-    stretch_order(p) = stretch_order(q);
+-    shrink_order(p) = shrink_order(q);
+-    return p;
+-}
+-
+-@ Glue nodes that are more or less anonymous are created by |new_glue|,
+-whose argument points to a glue specification.
+-
+-@c
+-halfword new_glue(halfword q)
+-{
+-    halfword p = new_node(glue_node, normal);

+-    stretch_order(p) = stretch_order(q);
+-    shrink_order(p) = shrink_order(q);
+-    return p;
+-}
+-
+-@ Still another subroutine is needed: This one is sort of a combination
+-of |new_param_glue| and |new_glue|. It creates a glue node for one of
+-the current glue parameters, but it makes a fresh copy of the glue
+-specification, since that specification will probably be subject to change,
+-while the parameter will stay put.
+-
+-/*
+-    The global variable |temp_ptr| is set to the address of the new spec.
+-*/
+-
+-@c
+-halfword new_skip_param(int n)
+-{
+-    halfword p = new_node(glue_node, n + 1);
+-    halfword q = glue_par(n);
+-    width(p) = width(q);
+-    stretch(p) = stretch(q);
+-    shrink(p) = shrink(q);
+-    stretch_order(p) = stretch_order(q);
+-    shrink_order(p) = shrink_order(q);
+-    return p;
+-}
+-
+-@ A |kern_node| has a |width| field to specify a (normally negative)
+-amount of spacing. This spacing correction appears in horizontal lists
+-between letters like A and V when the font designer said that it looks
+-better to move them closer together or further apart. A kern node can
+-also appear in a vertical list, when its `|width|' denotes additional
+-spacing in the vertical direction. The |subtype| is either |normal| (for
+-kerns inserted from font information or math mode calculations) or |explicit|
+-(for kerns inserted from \.{\\kern} and \.{\\/} commands) or |acc_kern|
+-(for kerns inserted from non-math accents) or |mu_glue| (for kerns
+-inserted from \.{\\mkern} specifications in math formulas).
+-
+-@ The |new_kern| function creates a kern node having a given width.
+-
+-@c
+-halfword new_kern(scaled w)
+-{
+-    halfword p = new_node(kern_node, normal);
+-    width(p) = w;
+-    return p;
+-}
+-
+-@ A |penalty_node| specifies the penalty associated with line or page
+-breaking, in its |penalty| field. This field is a fullword integer, but
+-the full range of integer values is not used: Any penalty |>=10000| is
+-treated as infinity, and no break will be allowed for such high values.
+-Similarly, any penalty |<=-10000| is treated as negative infinity, and a
+-break will be forced.
+-
+-@ Anyone who has been reading the last few sections of the program will
+-be able to guess what comes next.
+-
+-@c
+-halfword new_penalty(int m, int s)
+-{
+-    halfword p = new_node(penalty_node, 0); /* the |subtype| is not used */
+-    penalty(p) = m;
+-    subtype(p) = s;
+-    return p;
+-}
+-
+-@ You might think that we have introduced enough node types by now. Well,
+-almost, but there is one more: An |unset_node| has nearly the same format
+-as an |hlist_node| or |vlist_node|; it is used for entries in \.{\\halign}
+-or \.{\\valign} that are not yet in their final form, since the box
+-dimensions are their ``natural'' sizes before any glue adjustment has been
+-made. The |glue_set| word is not present; instead, we have a |glue_stretch|
+-field, which contains the total stretch of order |glue_order| that is
+-present in the hlist or vlist being boxed.
+-Similarly, the |shift_amount| field is replaced by a |glue_shrink| field,
+-containing the total shrink of order |glue_sign| that is present.
+-The |subtype| field is called |span_count|; an unset box typically
+-contains the data for |qo(span_count)+1| columns.
+-Unset nodes will be changed to box nodes when alignment is completed.
+-
+-In fact, there are still more types coming. When we get to math formula
+-processing we will see that a |style_node| has |type=14|; and a number
+-of larger type codes will also be defined, for use in math mode only.
+-
+-Warning: If any changes are made to these data structure layouts, such as
+-changing any of the node sizes or even reordering the words of nodes,
+-the |copy_node_list| procedure and the memory initialization code
+-below may have to be changed. Such potentially dangerous parts of the
+-program are listed in the index under `data structure assumptions'.
+-@!@^data structure assumptions@>

+-the \.{WEB} macro definitions above, so that format changes will leave
+-\TeX's other algorithms intact.

++    rather difficult for Type 2 charstrings due to the bias which depends on the
++    total number of subroutines. Replacing callgsubr/callsubr calls with the
++    content of the corresponding subroutine charstring may be more efficient than
++    putting dummy subroutines in the case of subsetted font. Adobe distiller
++    seems doing same thing.
++
++    And also note that subroutine numbers within subroutines can depend on the
++    content of operand stack as follows:

++    \stoptyping
++
++    I've not implemented the `random' operator which generates a pseudo-random
++    number in the range (0, 1] and push them into argument stack. How
++    pseudo-random sequences are generated is not documented in the Type 2
++    charstring spec.

+%description ae
+A set of virtual fonts which emulates T1 coded fonts using the
+standard CM fonts. The package name, AE fonts, supposedly
+stands for "Almost European". The main use of the package was
+to produce PDF files using Adobe Type 1 versions of the CM
+fonts instead of bitmapped EC fonts. Note that direct
+substitutes for the bitmapped EC fonts are now available, via
+the CM-super, Latin Modern and (in a restricted way) CM-LGC
+font sets.

+An extended set of fonts for use in mathematics, including:
+extra mathematical symbols; blackboard bold letters (uppercase
+only); fraktur letters; subscript sizes of bold math italic and
+bold Greek letters; subscript sizes of large symbols such as
+sum and product; added sizes of the Computer Modern small caps
+font; cyrillic fonts (from the University of Washington); Euler
+mathematical fonts. All fonts are provided as Adobe Type 1
+files, and all except the Euler fonts are provided as Metafont
+source. The distribution also includes the canonical Type 1
+versions of the Computer Modern family of fonts. Plain TeX and
+LaTeX macros for using the fonts are provided.

+%description amsmath
+The package provides the principal packages in the AMS-LaTeX
+distribution. It adapts for use in LaTeX most of the
+mathematical features found in AMS-TeX; it is highly
+recommendsd as an adjunct to serious mathematical typesetting
+in LaTeX. When amsmath is loaded, AMS-LaTeX packages amsbsy
+(for bold symbols), amsopn (for operator names) and amstext
+(for text embdedded in mathematics) are also loaded. Amsmath is
+part of the LaTeX required distribution; however, several
+contributed packages add still further to its appeal; examples
+are empheq, which provides functions for decorating and
+highlighting mathematics, and ntheorem, for specifying theorem
+(and similar) definitions.

+provided that can be used, for example, for per chapter/section
+appendices. The word `Appendix' or similar can be prepended to
+the appendix number for article class documents. The word
+`Appendices' or similar can be added to the table of contents
+before the appendices are listed. The word `Appendices' or
+similar can be typeset as a \part-like heading (page) in the
+body. An appendices environment is provided which can be used
+instead of the \appendix command.

+%description arabxetex
+ArabXeTeX provides a convenient ArabTeX-like user-interface for
+typesetting languages using the Arabic script in XeLaTeX, with
+flexible access to font features. Input in ArabTeX notation can
+be set in three different vocalization modes or in roman
+transliteration. Direct UTF-8 input is also supported. The
+parsing and converting of ArabTeX input to Unicode is done by
+means of TECkit mappings. Version 1.0 provides support for
+Arabic, Maghribi Arabic, Farsi (Persian), Urdu, Sindhi,
+Kashmiri, Ottoman Turkish, Kurdish, Jawi (Malay) and Uighur.
+The documentation (not yet complete) covers topics such as
+typesetting the Holy Quran, typesetting bidirectional critical
+editions (with ednotes), and information on various recommended
+OpenType fonts for the Arabic script and for transliterating
+Oriental languages.

+%description attachfile
+Starting with PDF 1.3 (Adobe Acrobat 4.0), PDF files can
+contain file attachments -- arbitrary files that a reader can
+extract, just like attachments to an e-mail message. The
+attachfile package brings this functionality to pdfLaTeX and
+provides some additional features not available in Acrobat,
+such as the ability to use arbitrary LaTeX code for the file
+icon -- including things like \includegraphics, tabular, and
+mathematics. Settings can be made either globally or on a per-
+attachment basis. Attachfile makes it easy to attach files and
+customize their appearance in the enclosing document. The
+package supports the Created, Modified, and Size keys in the
+EmbeddedFile's Params dictionary.

+%description babel
+The package manages culturally-determined typographical (and
+other) rules, and hyphenation patterns for a wide range of
+languages. A document may select a single language to be
+supported, or it may select several, in which case the document
+may switch from one language to another in a variety of ways.
+Note that the package has contributions for several languages
+that remain to be incorporated. Examples are: Arabic; Magyar
+(Hungarian); Serbian written in cyrillic; Spanish; and Spanish,
+using Mexican conventions.. Users of XeTeX are advised to use
+polyglossia rather than Babel.

+%description beamer
+The beamer LaTeX class can be used for producing slides. Its
+functionality is similar to Prosper but does not need any
+external programs and can directly produce a presentation using
+pdflatex. Beamer uses pgf for pdf/ps independent graphics.
+Frames are created using \frame{...}, and a frame can build
+multiple slides through a simple notation for specifying
+material for each slide within a frame. Beamer supports
+bibliographies, appendicies and transitions. Short versions of
+title, authors, institute can also be specified as optional
+parameters. A \plainframe{} allows a picture, for example, to
+fill the whole frame. Support figure and table environments,
+transparency effects, a \transduration command, animation
+commands, a pauses environment. Beamer also provides
+compatibility with other packages like prosper. The package now
+incorporates the functionality of the former translator
+package, which is used for customising the package for use in
+other language environments.

+%description pgf
+PGF is a macro package for creating graphics. It is platform-
+and format-independent and works together with the most
+important TeX backend drivers, including pdftex and dvips. It
+comes with a user-friendly syntax layer called TikZ. Its usage
+is similar to pstricks and the standard picture environment.
+PGF works with plain (pdf-)TeX, (pdf-)LaTeX, and ConTeXt.
+Unlike pstricks, it can produce either PostScript or PDF
+output.

+%description bibtex
+BibTeX allows the user to store his citation data in generic
+form, while printing citations in a document in the form
+specified by a BibTeX style, to be specified in the document
+itself (one often needs a LaTeX citation-style package, such as
+natbib as well). BibTeX itself is an ASCII-only program; there
+is, however, a version that copes with 8-bit character sets.
+However, BibTeX's facilities rapidly run out as one moves away
+from simple ASCII (for example, in the various national sorting
+rules for languages expressed in different parts of ISO-8859 --
+the "ISO Latin" series). For more flexibility, the user is
+urged to consider using biber with biblatex to typeset its
+output. In particular, it is best to avoid BibTeX in favour of
+biblatex, if at all possible.

+%description bibtopic
+The package allows the user to include several bibliographies
+covering different 'topics' or bibliographic material into a
+document (e.g., one bibliography for primary literature and one
+for secondary literature). The package provides commands to
+include either all references from a .bib file, only the
+references actually cited or those not cited in your document.
+The user has to construct a separate .bib file for each
+bibliographic 'topic', each of which will be processed
+separately by BibTeX. If you want to have bibliographies
+specific to one part of a document, see the packages bibunits
+or chapterbib.

+%description bigfoot
+The package aims to provide a 'one-stop' solution to
+requirements for footnotes. It offers: - Multiple footnote
+apparatus superior to that of the manyfoot; - Footnotes can be
+formatted in separate paragraphs, or be run into a single
+paragraph (this choice may be selected per footnote series); -
+Things you might have expected (like \verb-like material in
+footnotes, and colour selections over page breaks) now work.
+Note that the majority of the bigfoot package's interface is
+identical to that of manyfoot; users should seek information
+from that package's documentation. The bigfoot bundle also
+provides the perpage and suffix packages.

+The caption package provides many ways to customise the
+captions in floating environments like figure and table, and
+cooperates with many other packages. Facilities include
+rotating captions, sideways captions, continued captions (for
+tables or figures that come in several parts). A list of
+compatibility notes, for other packages, is provided in the
+documentation. The package also provides the "caption outside
+float" facility, in the same way that simpler packages like
+capt-of do. The package supersedes caption2.

+%description cjk
+CJK is a macro package for LaTeX, providing simultaneous
+support for various Asian scripts in many encodings (including
+Unicode): - Chinese (both traditional and simplified), -
+Japanese, - Korean and - Thai. A special add-on feature is an
+interface to the Emacs editor (cjk-enc.el) which gives
+simultaneous, easy-to-use support to a bunch of other scripts
+in addition to the above: - Cyrillic, - Greek, - Latin-based
+scripts, - Russian and - Vietnamese.

+The package provides the \collect@body command (as in amsmath),
+as well as a \long version \Collect@Body, for collecting the
+body text of an environment. These commands are used to define
+a new author interface to creating new environments. For
+example: \NewEnviron{test} wraps the entire environment body in
+square brackets, doing the right thing in ignoring leading and
+trailing spaces.

+%description wadalab
+These are font bundles for the Japanese Wadalab fonts which
+work with the CJK package. All subfonts now have glyph names
+compliant to the Adobe Glyph List, making ToUnicode CMaps in
+PDF documents (created automatically by dvipdfmx) work
+correctly. All font bundles now contain virtual Unicode
+subfonts.

+%description cm-lgc
+The fonts are converted from Metafont sources of the Computer
+Modern font families, using textrace. Supported encodings are:
+T1 (Latin), T2A (Cyrillic), LGR (Greek) and TS1. The package
+also includes Unicode virtual fonts for use with Omega. The
+font set is not a replacement for any of the other Computer
+Modern-based font sets (for example, cm-super for Latin and
+Cyrillic, or cbgreek for Greek), since it is available at a
+single size only; it offers a compact set for 'general'
+working. The fonts themselves are encoded to external
+standards, and virtual fonts are provided for use with TeX.

+%description cm-super
+CM-Super family of fonts are Adobe Type 1 fonts that replace
+the T1/TS1-encoded Computer Modern (EC/TC), T1/TS1-encoded
+Concrete, T1/TS1-encoded CM bright and LH fonts (thus
+supporting all European languages except Greek, and all
+Cyrillic-based languages), and bringing many ameliorations in
+typesetting quality. The fonts exhibit the same metrics as the
+MetaFont-encoded originals.

+%description cm
+Knuth's final iteration of his re-interpretation of a c.19
+Modern-style font from Monotype. The family is comprehensive,
+offering both sans and roman styles, and a monospaced font,
+together with mathematics fonts closely integrated with the
+mathematical facilities of TeX itself. The base fonts are
+distributed as Metafont source, but autotraced PostScript Type
+1 versions are available (one version in the AMS fonts
+distribution, and also the BaKoMa distribution). The Computer
+Modern fonts have inspired many later families, notably the
+European Computer Modern and the Latin Modern families.

+%description hyph-utf8
+Modern native UTF-8 engines such as XeTeX and LuaTeX need
+hyphenation patterns in UTF-8 format, whereas older systems
+require hyphenation patterns in the 8-bit encoding of the font
+in use (such encodings are codified in the LaTeX scheme with
+names like OT1, T2A, TS1, OML, LY1, etc). The present package
+offers a collection of conversions of existing patterns to UTF-
+8 format, together with converters for use with 8-bit fonts in
+older systems. Since hyphenation patterns for Knuthian-style
+TeX systems are only read at iniTeX time, it is hoped that the
+UTF-8 patterns, with their converters, will completely supplant
+the older patterns.

+able to use modern (OpenType) fonts (for both text and
+mathematics). It should be noted that LuaTeX is still under
+development; its specification has been declared stable, but

+customisation. In 2006, Thomas Esser announced he would no
+longer be able to support, or to produce new versions of,
+teTeX. With the appearance of TeX live 2007 (whose Unix-system
+TeX support originally derived from teTeX), no-one should be
+using teTeX at all, in new applications. One of the "schemes"
+available when installing TeX live provides a configuration
+very close to that of the old teTeX, but using modern versions
+of programs and packages.

+%description tex
+TeX is a typesetting system that incorporates a macro
+processor. A TeX source document specifies or incorporates a
+number of macro definitions that instruct the TeX engine how to
+typeset the document. The TeX engine also uses font metrics
+generated by Metafont, or by any of several other mechanisms
+that incorporate fonts from other sources into an environment
+suitable for TeX. TeX has been, and continues, a basis and an
+inspiration for several other programs, including e-TeX and
+PDFTeX. The distribution includes the source of Knuth's TeX
+book; this source is there to read, as an example of writing
+TeX -- it should not be processed without Knuth's direct
+permission.

+%description fpl
+The FPL Fonts provide a set of SC/OsF fonts for URW Palladio L
+which are compatible with respect to metrics with the Palatino
+SC/OsF fonts from Adobe. Note that it is not my aim to exactly
+reproduce the outlines of the original Adobe fonts. The SC and
+OsF in the FPL Fonts were designed with the glyphs from URW
+Palladio L as starting point. For some glyphs (e.g. 'o') I got
+the best result by scaling and boldening. For others (e.g. 'h')
+shifting selected portions of the character gave more
+satisfying results. All this was done using the free font
+editor FontForge. The kerning data in these fonts comes from
+Walter Schmidt's improved Palatino metrics. LaTeX use is
+enabled by the mathpazo package, which is part of the psnfss
+distribution.

+%description lm
+The Latin Modern family of fonts consists of 72 text fonts and
+20 mathematics fonts, and is based on the Computer Modern fonts
+released into public domain by AMS (copyright (c) 1997 AMS).
+The lm font set contains a lot of additional characters, mainly
+accented ones, but not exclusively. There is one set of fonts,
+available both in Adobe Type 1 format (*.pfb) and in OpenType
+format (*.otf). There are five sets of TeX Font Metric files,
+corresponding to: Cork encoding (cork-*.tfm); QX encoding (qx-
+*.tfm); TeX'n'ANSI aka LY1 encoding (texnansi-*.tfm); T5
+(Vietnamese) encoding (t5-*.tfm); and Text Companion for EC
+fonts aka TS1 (ts1-*.tfm).

+%description mathpazo
+The Pazo Math fonts are a family of PostScript fonts suitable
+for typesetting mathematics in combination with the Palatino
+family of text fonts. The Pazo Math family is made up of five
+fonts provided in Adobe Type 1 format (PazoMath, PazoMath-
+Italic, PazoMath-Bold, PazoMath-BoldItalic, and
+PazoMathBlackboardBold). These contain, in designs that match
+Palatino, glyphs that are usually not available in Palatino and
+for which Computer Modern looks odd when combined with
+Palatino. These glyphs include the uppercase Greek alphabet in
+upright and slanted shapes in regular and bold weights, the
+lowercase Greek alphabet in slanted shape in regular and bold
+weights, several mathematical glyphs (partialdiff, summation,
+product, coproduct, emptyset, infinity, and proportional) in
+regular and bold weights, other glyphs (Euro and dotlessj) in
+upright and slanted shapes in regular and bold weights, and the
+uppercase letters commonly used to represent various number
+sets (C, I, N, Q, R, and Z) in blackboard bold. The set also
+includes a set of 'true' small-caps fonts, also suitable for
+use with Palatino (or one of its clones). LaTeX macro support
+(using package mathpazo.sty) is provided in psnfss (a required
+part of any LaTeX distribution).

+%description pxfonts
+Pxfonts supplies virtual text roman fonts using Adobe Palatino
+(or URWPalladioL) with some modified and additional text
+symbols in the OT1, T1, and TS1 encodings; maths alphabets
+using Palatino/Palladio; maths fonts providing all the symbols
+of the Computer Modern and AMS fonts, including all the Greek
+capital letters from CMR; and additional maths fonts of various
+other symbols. The set is complemented by a sans-serif set of
+text fonts, based on Helvetica/NimbusSanL, and a monospace set
+derived from the parallel TX font set. All the fonts are in
+Type 1 format (AFM and PFB files), and are supported by TeX
+metrics (VF and TFM files) and macros for use with LaTeX.

+%description tex-gyre
+The TeX-GYRE bundle consists of six font families: TeX Gyre
+Adventor is based on the URW Gothic L family of fonts (which is
+derived from ITC Avant Garde Gothic, designed by Herb Lubalin
+and Tom Carnase). TeX Gyre Bonum is based on the URW Bookman L
+family (from Bookman Old Style, designed by Alexander
+Phemister). TeX Gyre Chorus is based on URW Chancery L Medium
+Italic (from ITC Zapf Chancery, designed by Hermann Zapf in
+1979). TeX-Gyre Cursor is based on URW Nimbus Mono L (based on
+Courier, designed by Howard G. Kettler in 1955, for IBM). TeX
+Gyre Heros is based on URW Nimbus Sans L (from Helvetica,
+prepared by Max Miedinger, with Eduard Hoffmann in 1957). TeX
+Gyre Pagella is based on URW Palladio L (from Palation,
+designed by Hermann Zapf in the 1940s). TeX Gyre Schola is
+based on the URW Century Schoolbook L family (which was
+designed by Morris Fuller Benton for the American Type
+Founders). TeX Gyre Termes is based on the URW Nimbus Roman No9
+L family of fonts (whose original, Times, was designed by
+Stanley Morison together with Starling Burgess and Victor
+Lardent and first offered by Monotype). The constituent
+standard faces of each family have been greatly extended, and
+contain nearly 1200 glyphs each (though Chorus omits Greek
+support, has no small-caps family and has approximately 900
+glyphs). Each family is available in Adobe Type 1 and Open Type
+formats, and LaTeX support (for use with a variety of
+encodings) is provided. Vietnamese and Cyrillic characters were
+added by Han The Thanh and Valek Filippov, respectively.

+%description latex
+LaTeX is a widely-used macro package for TeX, providing many
+basic document formating commands extended by a wide range of
+packages. It is a development of Leslie Lamport's original
+LaTeX 2.09, and superseded the older system in June 1994. The
+basic distribution is catalogued separately, at latex-base;
+apart from a large set of contributed packages and third-party
+documentation (elsewhere on the archive), the distribution
+includes: - a bunch of required packages, which LaTeX authors
+are "entitled to assume" will be present on any system running
+LaTeX; and - a minimal set of documentation detailing
+differences from the 'old' version of LaTeX in the areas of
+user commands, font selection and control, class and package
+writing, font encodings, configuration options and modification
+of LaTeX. For downloading details, see the linked catalogue
+entries above.

+%description latex-fonts
+This is a collection of fonts for use with standard latex
+packages and classes. It includes 'invisible' fonts (for use
+with the slides class), line and circle fonts (for use in the
+picture environment) and 'latex symbol' fonts. For full support
+of a latex installation, some Computer Modern font variants
+cmbsy(6-9), cmcsc(8,9), cmex(7-9) and cmmib(5-9) from the
+amsfonts distribution, are also necessary. The fonts are
+available as Metafont source, and metric (tfm) files are also
+provided. Most of the fonts are also available in Adobe Type 1
+format, in the amsfonts distribution.

+%description tex4ht
+A converter from TeX and LaTeX to SGML-based formats such as
+(X)HTML, MathML, OpenDocument, and DocBook, providing a
+configurable (La)TeX-based authoring system for hypertext.
+Tex4ht does not parse (La)TeX source (so that it avoids the
+difficulties encountered by many other converters, arising from
+the irregularity of (La)TeX syntax). Instead, Tex4ht uses
+(La)TeX itself (with an extra macro package) to produce a non-
+standard DVI file that it can then process. This technique
+allows TeX4ht to approach the robustness characteristic of
+restricted-syntax systems such as hyperlatex and gellmu. Note
+that CTAN no longer holds the definitive sources of the
+package: see the 'Readme' file.

+The package provides an easy and flexible user interface to

+just \usepackage[margin=2cm,nohead]{geometry}. The package
+knows about all the standard paper sizes, so that the user need
+not know what the nominal 'real' dimensions of the paper are,
+just its standard name (such as a4, letter, etc.). An important
+feature is the package's ability to communicate the paper size
+it's set up to the output (whether via DVI \specials or via

+%description graphics
+The package was designed to accommodate all needs for inclusion
+of graphics in LaTeX documents, replacing many earlier packages
+used in LaTeX 2.09. The package aims to give a consistent
+interface to including the file types that are understood in
+your output, by use of 'printer drivers' (now known, simply, as
+'drivers'). The distribtion of the package contains several
+drivers, but others (for example, pdfTeX) are distributed
+separately. The package also offers several means of
+manipulating graphics in the course of inserting them into a
+document (for example, rotation and scaling). For extended
+documentation see epslatex. The package is part of the graphics
+bundle, which is one of the collections in the LaTeX 'required'

+%description pslatex
+A small package that makes LaTeX default to 'standard'
+PostScript fonts. It is basically a merger of the times and the
+(obsolete) mathptm packages from the psnfss suite. You must
+have installed standard LaTeX and the psnfss PostScript fonts
+to use this package. The main novel feature is that the pslatex
+package tries to compensate for the visual differences between
+the Adobe fonts by scaling Helvetica by 90%, and 'condensing'
+Courier (i.e. scaling horizontally) by 85%. The package is
+supplied with a (unix) shell file for a 'pslatex' command that
+allows standard LaTeX documents to be processed, without
+needing to edit the file. Note that current psnfss uses a
+different technique for scaling Helvetica, and treats Courier
+as a lost cause (there are better free fixed-width available
+now, than there were when pslatex was designed). As a result,
+pslatex is widely considered obsolete.

+%description psnfss
+Font definition files, macros and font metrics for freely-
+available Adobe Type 1 fonts. The font set consists of the
+'LaserWriter 35' set (originally 'freely available' because
+embedded in PostScript printers), and a variety of other free
+fonts, together with some additions. Note that while many of
+the fonts are available in PostScript (and other) printers,
+most publishers require fonts embedded in documents, which
+requires that you have the fonts in your TeX system.
+Fortunately, there are free versions of the fonts from URW
+(available in the URW base5 bundle). The base set of text fonts
+covered by PSNFSS are: AvantGarde, Bookman, Courier, Helvetica,
+New Century Schoolbook, Palatino, Symbol, Times Roman and Zapf
+Dingbats. In addition, the fonts Bitstream Charter and Adobe
+Utopia are covered (those fonts were contributed to the Public
+Domain by their commercial foundries). Separate packages are
+provided to load each font for use as main text font. The
+packages helvet (which allows Helvetica to be loaded with its
+size scaled to something more nearly appropriate for its use as
+a Sans-Serif font to match Times) and pifont (which provides
+the means to select single glyphs from symbol fonts) are
+tailored to special requirements of their fonts. Mathematics
+are covered by the mathptmx package, which constructs passable
+mathematics from a combination of Times Roman, Symbol and some
+glyphs from Computer Modern, and by Pazo Math (optionally
+extended with the fpl small-caps and old-style figures fonts)
+which uses Palatino as base font, with the mathpazo fonts. The
+bundle as a whole is part of the LaTeX 'required' set of
+packages.

+%description ec
+The EC fonts are European Computer Modern Fonts, supporting the
+complete LaTeX T1 encoding defined at the 1990 TUG conference
+hold at Cork/Ireland. These fonts are intended to be stable
+with no changes being made to the tfm files. The set also
+contains a Text Companion Symbol font, called tc, featuring
+many useful characters needed in text typesetting, for example
+oldstyle digits, currency symbols (including the newly created
+Euro symbol), the permille sign, copyright, trade mark and
+servicemark as well as a copyleft sign, and many others. Recent
+releases of LaTeX2e support the EC fonts. The EC fonts
+supersede the preliminary version released as the DC fonts. The
+fonts are available in (traced) Adobe Type 1 format, as part of
+the cm-super bundle. The other Computer Modern-style T1-encoded
+Type 1 set, Latin Modern, is not actually a direct development
+of the EC set, and differs from the EC in a number of
+particulars.

+%description koma-script
+The KOMA-Script bundle provides drop-in replacements for the
+article/report/book classes with emphasis on typography and
+versatility. There is also a letter class, different from all
+other letter classes. It also offers e.g. a package for
+calculated type areas in the way laid down by the typographer
+Jan Tschichold, a package for easily changing and defining of
+page styles, a package for getting not only the current date
+but also the name of day and a package for getting current
+time. All these packages may be used not only with KOMA-Script
+classes but also with standard classes. Since every package has
+its own version number, the number below is only the version of
+scrbook, scrreprt, scrartcl, scrlttr2 and typearea. These are
+the main parts of the bundle.

+The bundle holds prototype implementations of concepts for a
+LaTeX designer interface, to be used with the experimental
+LaTeX kernel as programming tools and kernel support. Packages
+provided in this release are: - l3keys2e, which makes the
+facilities of the kernel module l3keys available for use by
+LaTeX 2e packages; - xfrac, which provides flexible split-level
+fractions; - xparse, which provides a high-level interface for
+declaring document commands; and - xtemplate, which provides a
+means of defining generic functions using a key-value syntax.
+All the files of the bundle are also available in the
+Subversion (SVN) repository of the LaTeX3 Project.

+%description l3experimental
+The l3experimental packages are a collection of experimental
+implementations for aspects of the LaTeX3 kernel, dealing with
+higher-level ideas such as the Designer Interface. Some of them
+work as stand alone packages, providing new functionality, and
+can be used on top of LaTeX2e with no changes to the existing
+kernel. The present release includes: - xgalley, which controls
+boxes receiving text for typesetting. - l3dt: kernel support
+for data tables; - l3galley: kernel support for xgalley; -
+l3regex: kernel support for regular expression search and
+replace operations; - l3sort: kernel support for sorting
+sequences, token lists or comma-lists, according to user-
+specified comparison criteria; - l3str: kernel support for
+string manipulation; - l3tl-build: kernel support for token
+list building; - l3tl_analysis: kernel support for token list
+analysis; and - xcoffins, which allows the alignment of boxes
+using a series of 'handle' positions, supplementing the simple
+TeX reference point. All the files of the bundle are also
+available in the Subversion (SVN) repository of the LaTeX3
+Project.

+%description memoir
+The memoir class is for typesetting poetry, fiction, non-
+fiction, and mathematical works. Permissible document 'base'
+font sizes range from 9 to 60pt. There is a range of page-
+styles and well over a dozen chapter-styles to choose from, as
+well as methods for specifying your own layouts and designs.
+The class also provides the functionality of over thirty of the
+more popular packages, thus simplifying document sources. The
+class automatically loads an associated patch file mempatch;
+the patch file may be updated from time to time, between
+releases of the class itself. (The patch file stays around even
+when there are no extant patches.) Users who wish to use the
+hyperref package, in a document written with the memoir class,
+should also use the memhfixc package (part of this bundle).
+Note, however, that current versions of hyperref actually load
+the package automatically if they detect that they are running
+under memoir.

+%description microtype
+The package provides a LaTeX interface to the micro-typographic
+extensions that were introduced by pdfTeX and have since also
+propagated to XeTeX and LuaTeX: most prominently, character
+protrusion and font expansion, furthermore the adjustment of
+interword spacing and additional kerning, as well as
+hyphenatable letterspacing (tracking) and the possibility to
+disable all or selected ligatures. These features may be
+applied to customisable sets of fonts, and all micro-
+typographic aspects of the fonts can be configured in a
+straight-forward and flexible way. Settings for various fonts
+are provided. Note that character protrusion requires pdfTeX,
+LuaTeX, or XeTeX. Font expansion works with pdfTeX or LuaTeX.
+The package will by default enable protrusion and expansion if
+they can safely be assumed to work. Disabling ligatures
+requires pdfTeX or LuaTeX, while the adjustment of interword
+spacing and of kerning only works with pdfTeX. Letterspacing is
+available with pdfTeX or LuaTeX. The alternative package
+`letterspace', which also works with plain TeX, provides the
+user commands for letterspacing only, omitting support for all
+other extensions.

+%description seminar
+A class that produces overhead slides (transparencies), with
+many facilities. The class requires availability of the
+fancybox package. Seminar is also the basis of other classes,
+such as prosper. In fact, seminar is not nowadays reckoned a
+good basis for a presentation -- users are advised to use more
+recent classes such as powerdot or beamer, both of which are
+tuned to 21st-century presentation styles. Note that the
+seminar distribution relies on the xcomment package, which was
+once part of the bundle, but now has a separate existence.

+%description subfig
+The package provides support for the manipulation and reference
+of small or 'sub' figures and tables within a single figure or
+table environment. It is convenient to use this package when
+your subfigures are to be separately captioned, referenced, or
+are to be included in the List-of-Figures. A new \subfigure
+command is introduced which can be used inside a figure
+environment for each subfigure. An optional first argument is
+used as the caption for that subfigure. This package supersedes
+the subfigure package (which will continue to be supported, but
+no longer maintained). The name has changed because the subfig
+package is not completely backward compatible with the older
+subfigure package due to an extensive rewrite to use the new
+caption package to produce its subcaptions. The major advantage
+to the new package is that the user interface is keyword/value
+driven and easier to use. To ease the transition from the
+subfigure package it includes a configuration file (subfig.cfg)
+which nearly emulates the subfigure package.

+an argument.) The command is intended for email addresses,
+hypertext links, directories/paths, etc., which normally have
+no spaces, so by default the package ignores spaces in its
+argument. However, a package option "allows spaces", which is
+useful for operating systems where spaces are a common part of

+Font encoding definitions for unicode fonts loaded by LaTeX in

+designed for use with XeTeX, which the fontspec uses for
+unicode fonts which require no macro-level processing for
+accents, and -- EU2, which provides the same facilities for use
+with LuaTeX. Neither encoding places any restriction on the
+glyphs provided by a font; use of EU2 causes the package
+euxunicode to be loaded (the package is part of this
+distribution). The package includes font definition files for
+use with the Latin Modern OpenType fonts.

+%description xetex
+XeTeX is an extension of TeX that integrates TeX's typesetting capabilities
+with (a) the Unicode text encoding standard (supporting most of the world’s
+scripts) and (b) modern font technologies (TrueType and OpenType) and text
+layout services (AAT, OpenType layout, SIL Graphite) provided by the host
+operating system and available libraries.
+
+With XeTeX, the advanced typographic features provided by OpenType fonts become
+available for all TeX users, as well as support for complex non-roman scripts.
+XeTeX also eliminates the complex task of managing a TeX font installation.
+XeTeX is now part of the standard TeX distribution TeXLive and works well with
+TeX macro packages like LaTeX and ConTeXt.

+%description csquotes
+This package provides advanced facilities for inline and
+display quotations. It is designed for a wide range of tasks
+ranging from the most simple applications to the more complex
+demands of formal quotations. The facilities include commands,
+environments, and user-definable 'smart quotes' which
+dynamically adjust to their context. Quotation marks are
+switched automatically if quotations are nested and they can be
+adjusted to the current language if the babel package is
+available. There are additional facilities designed to cope
+with the more specific demands of academic writing, especially
+in the humanities and the social sciences. All quote styles as
+well as the optional active quotes are freely configurable. The
+package is dependent on e-TeX, and requires the author's
+etoolbox package.

+restores the parent file name after the trailing \clearpage of
+an \included file; as a result, the macros may be usefully
+employed in the page header and footer of the last printed page
+of such a file. The depth of inclusion is made available,
+together with the "parent" (including file) and "parents" (all
+including files to the root of the tree). The package

+This program makes PNG and/or GIF graphics from DVI files as

+Speed. It offers very fast rendering of DVI as bitmap files,
+which makes it suitable for generating large amounts of images
+on-the-fly, as needed in preview-latex, WeBWorK and others; -
+It does not read the postamble, so it can be started before TeX
+finishes. There is a --follow switch that makes dvipng wait at
+end-of-file for further output, unless it finds the POST marker
+that indicates the end of the DVI; - Interactive query of
+options. dvipng can read options interactively through stdin,
+and all options are usable. It is even possible to change the
+input file through this interface. - Support for PK, VF,
+PostScript Type1, and TrueType fonts, colour specials, and
+inclusion of PostScript, PNG, JPEG or GIF images.

+%description epstopdf
+Epstopdf is a Perl script that converts an EPS file to an
+'encapsulated' PDF file (a single page file whose media box is
+the same as the original EPS's bounding box). The resulting
+file suitable for inclusion by PDFTeX as an image. The script
+is adapted to run both on Windows and on Unix-alike systems.
+The script makes use of Ghostscript for the actual conversion
+to PDF. It assumes Ghostscript version 6.51 or later, and (by
+default) suppresses its automatic rotation of pages where most
+of the text is not horizontal. LaTeX users may make use of the
+epstopdf package, which will run the epstopdf script "on the

+%description ifetex
+The package provides the switch \ifetex which indicates whether
+e-TeX is available or not. The package can be loaded as LaTeX
+package using \usepackage{ifetex} or in plain TeX using \input
+ifetex. In either case it aborts silently if the \ifetex macro
+is already defined. The package's test is whether \eTeXversion
+is defined as a primitive; if it is, the package assumes e-TeX
+features are available.

+%description kerkis
+Sans-serif Greek fonts to match the URW Bookman set (which are
+distributed with Kerkis). The Kerkis font set has some support
+for mathematics as well as other glyphs missing from the base
+URW Bookman fonts (the URW fonts are duplicated in the
+distribution). Macros are provided to use the fonts in OT1, T1
+(only NG/ng glyphs missing) and LGR encodings, as well as in
+mathematics; small caps and old-style number glyphs are also
+available. The philosophy, and the design process, of the
+Kerkis fonts is discussed in a paper in TUGboat 23(3/4), 2002.

+%description lualatex-math
+The package patches a few commands of the LaTeX2e kernel and
+the amsmath and mathtools packages to be more compatible with
+the LuaTeX engine. It is only meaningful for LuaLaTeX documents
+containing mathematical formulas, and does not exhibit any new
+functionality. The fixes are mostly moved from the unicode-math
+package to this package since they are not directly related to
+Unicode mathematics typesetting.

+%description mnsymbol
+MnSymbol is a symbol font family, designed to be used in

+Almost all of LaTeX and AMS mathematical symbols are provided;
+remaining coverage is available from the MinionPro font with
+the MinionPro package. The fonts are available in both MetaFont
+and Adobe Type 1 formats, and a comprehensive support package
+is provided. While the fonts were designed to fit with Minon
+Pro, the design should fit well with other renaissance or
+baroque faces: indeed, it will probably work with most fonts
+that are neither too wide nor too thin, for example Palatino or
+Times; it is known to look good with Sabon. There is no package
+designed to configure its use with any font other than Minion
+Pro, but (for example) simply loading mnsymbol after mathpazo
+will probably do what is needed.

+improvements to the description environment; - hyphenation of
+compound words; - new levels of footnotes; - space-filling
+patterns; - "poor man's" Black Board Bold symbols; - alignment
+of the content of a box; - use comma as decimal separator; -
+boxes with their own crop marks; - page cropmarks; -
+improvements to fancy headers; - float "styles", mini floats,
+side floats; - manually marked footnotes; - extension of
+amsmath; - control of paragraph skip; - an envelope to the
+graphicx package; - dashed and multiple rules; - alternative
+techniques for declarations of sections, captions, and toc-
+entries; - generalised text-stretching; - generation of new
+theorem-like environments; - control of the text area; -

+(picture drawing) macros, with a flexible interface and with
+colour support. There are macros for colouring or shading the
+cells of tables. The package pstricks-add contains bug-fixes
+and additions for pstricks (among other things). PSTricks uses
+PostScript \special commands, which are not supported by
+PDF(La)TeX. This limitation may be overcome by using either the

+%description soul
+Provides hyphenatable spacing out (letterspacing), underlining,
+striking out, etc., using the TeX hyphenation algorithm to find
+the proper hyphens automatically. The package also provides a
+mechanism that can be used to implement similar tasks, that
+have to treat text syllable by syllable. This is shown in two
+examples. The package itself does not support UTF-8 input in
+ordinary (PDF)LaTeX; some UTF-8 support is offered by package
+soulutf8

+Provides support for the manipulation and reference of small or

+subfigures are to be separately captioned, referenced, or are
+to be included in the List-of-Figures. A new \subfigure command
+is introduced which can be used inside a figure environment for
+each subfigure. An optional first argument is used as the
+caption for that subfigure. This package is now obsolescent:

+%description type1cm
+LaTeX, by default, restricts the sizes at which you can use its
+default computer modern fonts, to a fixed set of discrete sizes
+(effectively, a set specified by Knuth). The type1cm package
+removes this restriction; this is particularly useful when
+using scalable versions of the cm fonts (Bakoma, or the
+versions from BSR/Y&Y, or True Type versions from Kinch, PCTeX,
+etc.). In fact, since modern distributions will automatically
+generate any bitmap font you might need, type1cm has wider
+application than just those using scaleable versions of the
+fonts. Note that the LaTeX distribution now contains a package
+fix-cm, which performs the task of type1cm, as well as doing
+the same job for T1- and TS1-encoded ec fonts.

+%description ucs
+The bundle provides the ucs package, and utf8x.def, together
+with a large number of support files. The utf8x.def definition
+file for use with inputenc covers a wider range of Unicode
+characters than does utf8.def in the LaTeX distribution. The
+package provides facilities for efficient use of its large sets
+of Unicode characters. Glyph production may be controlled by
+various options, which permits use of non-ASCII characters when
+coding mathematical formulae. Note that the bundle previously
+had an alias "unicode"; that alias has now been withdrawn, and
+no package of that name now exists.

+%description unicode-math
+The current release of this package typesets mathematics with
+unicode input and using OpenType maths fonts. (There is little
+compatibility with older maths packages.) XeTeX support is well
+tested, though LuaTeX support less so. The package can typeset
+using STIX fonts, the XITS development of those fonts, the
+Asana-Math fonts, the Latin Modern Math, and the TeX Gyre Math
+font familiess, as well as the commercial Cambria Math fonts.
+There is no support for extra alphabets in the Unicode 'private
+use area'. The package relies on recent versions of the
+fontspec package and the l3kernel and l3packages bundles.

+%description tabu
+The package provides an environment, tabu, which will make any
+sort of tabular (that doesn't need to split across pages), and
+an environment longtabu which provides the facilities of tabu
+in a modified longtable environment. (Note that this latter
+offers an enhancement of ltxtable.) The package requires the
+array package, and needs e-TeX to run (since array.sty is
+present in every conforming distribution of LaTeX, and since
+every publicly available LaTeX format is built using e-TeX, the
+requirements are provided by default on any reasonable system).
+The package also requires xcolor for coloured rules in tables,
+and colortbl for coloured cells. The longtabu environment
+further requires that longtable be loaded. The package itself
+does not load any of these packages for the user. The tabu
+environment may be used in place of tabular, tabular* and
+tabularx environments, as well as the array environment in
+maths mode. It overloads tabularx's X-column specification,
+allowing a width specification, alignment (l, r, c and j) and
+column type indication (p, m and b). \begin{tabu} to <dimen>
+specifies a target width, and \begin{tabu} spread <dimen>
+enlarges the environment's "natural" width.

+through the zref-savepos package. Example: Some text:
+\begin{tabularx}\linegoal{|l|X|} \hline one & two \\ three &
+four \\\hline \end{tabularx} will position the table after the
+initial text, and make the table fill the rest of the line.

+%description breqn
+The package provides solutions to a number of common
+difficulties in writing displayed equations and getting high-

+'left...right' constructs cannot span lines. The breqn package
+makes them work as one would expect whether or not there is an
+intervening line break. The single most ambitious goal of the
+package, however, is to support automatic linebreaking of
+displayed equations. Such linebreaking cannot be done without
+substantial changes under the hood in the way formulae are
+processed; the code must be watched carefully, keeping an eye
+on possible glitches. The bundle also contains the flexisym and
+mathstyle packages, which are both designated as support for
+breqn.

+Maths versions of \makebox, \llap, \rlap etc.; Cramped math
+styles; and more... Mathtools requires mhsetup.

+of specifying a width, one specifies a tag. All eqparboxes with
+the same tag--regardless of where they are in the document--
+will stretch to fit the widest eqparbox with that tag. This
+simple, equal-width mechanism can be used for a variety of
+alignment purposes, as is evidenced by the examples in
+eqparbox's documentation. Various derivatives of \eqparbox are

+for variable width columns (\raggedright', \centering,
+\raggedleft, and normally justified). In contrast to tabularx's
+X columns, the width of each column is weighted according to
+the natural width of the widest cell in the column.

+Typewriter-style fonts are best for program listings, but
+Computer Modern Typewriter prints ` and ' as bent opening and

+both to open and to close quoted strings. The package switches
+the typewriter font to Computer Modern Typewriter in OT1
+encoding, and modifies the behaviour of verbatim, verbatim*,
+\verb, and \verb* to print in the "` and ' way". It does
+thisregardless of other fonts or encodings in use, so long as
+the package is loaded after the other fonts were. The package
+does not affect \tt, \texttt, etc.

+Dvisvgm is a command line utility that converts TeX DVI files
+to the XML-based Scalable Vector Graphics (SVG) format. It
+provides full font support including virtual fonts, font maps,
+and sub-fonts. If necessary, dvisvgm vectorizes Metafont's
+bitmap output in order to always create lossless scalable
+output. The embedded SVG fonts can optionally be replaced with
+graphics paths so that applications that don't support SVG
+fonts are enabled to render the graphics properly. Besides many
+other features, dvisvgm also supports color, emTeX, tpic, PDF
+mapfile and PostScript specials. Users will need a working TeX
+installation including the kpathsea library. For more detailed
+information, see the project page.

+%description translator
+This LaTeX package provides a flexible mechanism for
+translating individual words into different languages. For
+example, it can be used to translate a word like "figure" into,
+say, the German word "Abbildung". Such a translation mechanism
+is useful when the author of some package would like to
+localize the package such that texts are correctly translated
+into the language preferred by the user. This package is not
+intended to be used to automatically translate more than a few
+words.
