# Author: David Beazley (dave@dabeaz.com)

#
# Converts a UNIX-yacc specification file into a PLY-compatible
# specification.   To use, simply do this:
#
#   % python yply.py [-nocode] inputfile.y >myparser.py
#
# The output of this program is Python code. In the output,
# any C code in the original file is included, but is commented.
# If you use the -nocode option, then all of the C code in the
# original file is discarded.
#
# Disclaimer:  This just an example I threw together in an afternoon.
# It might have some bugs.  However, it worked when I tried it on
# a yacc-specified C++ parser containing 442 rules and 855 parsing
# states.
