%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

# 2to3--it is not necessary and may in fact break the implementation."

#

# However, one of the example files contains python 2 "print" syntax, which

# lead to syntax errors during byte-compilation

# So we fix this file with 2to3:
