# yc - yapp compile
#
# This calls 'yapp', distributed with the Parse::Yapp module, to
# compile the parser grammar and construct the ../Template/Grammar.pm
# file. The grammar is defined in ./Parser.yp. The skeleton file
# Grammar.pm.skel is used as a template for creating the grammar file.
# An output file 'Parser.output' is generated containing a summary of
# the rule and state tables.
#
# You only need to run this script if you have changed the grammar and
# wish to recompile it.
