#fix-info-dir was derived from update-info and gen-dir-node
|
||
# The skeleton file contains info topic names in the
|
||
# order they should appear in the output. There are three special
|
||
# lines that alter the behavior: a line consisting of just "--" causes
|
||
# the next line to be echoed verbatim to the output. A line
|
||
# containing just "%%" causes all the remaining filenames (wildcards
|
||
# allowed) in the rest of the file to be ignored. A line containing
|
||
# just "!!" exits the script when reached (unless preceded by a line
|
||
# containing just "--").

|
||
Options:
|
||
-c, --create create a new info node
|
||
-d, --delete delete invalid menu items (ignore missing menu items)
|
||
--debug print debug information to standard error path
|
||
--help print this help message and exit
|
||
--version print current version and exit
|
||
Backup of the info node has a '.old' suffix added. This is a shell script.

This is the file .../info/$DIR_FILE, which contains the topmost node of the
|
||
Info hierarchy. The first time you invoke Info you start off
|
||
looking at that node, which is ($DIR_FILE)Top.
|
||
|
||
|
||
File: $DIR_FILE Node: Top This is the top of the INFO tree
|
||
|
||
This (the Directory node) gives a menu of major topics.
|
||
Typing "q" exits, "?" lists all Info commands, "d" returns here,
|
||
"h" gives a primer for first-timers,
|
||
"mEmacs<Return>" visits the Emacs topic, etc.
|
||
|
||
In Emacs, you can click mouse button 2 on a menu item or cross reference
|
||
to select it.
