# ply: ygen.py
#
# This is a support program that auto-generates different versions of the YACC parsing
# function with different features removed for the purposes of performance.
#
# Users should edit the method LRParser.parsedebug() in yacc.py.   The source code
# for that method is then used to create the other methods.   See the comments in
# yacc.py for further details.
