%description
PLY is a straightforward lex/yacc implementation. Here is a list of its 
essential features:
* It is implemented entirely in Python.
* It uses LR-parsing which is reasonably efficient and well suited for larger 
  grammars.
* PLY provides most of the standard lex/yacc features including support 
  for empty productions, precedence rules, error recovery, and support 
  for ambiguous grammars.
* PLY is straightforward to use and provides very extensive error checking.
* PLY doesn't try to do anything more or less than provide the basic lex/yacc 
  functionality. In other words, it's not a large parsing framework or a 
  component of some larger system.

# The README states: "You should not convert PLY using
