# 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.
#
# This script uses a slightly modified version of the Parse::Yapp module,
# version 0.31.  The parse_yapp_patch patch file can be applied to the 
# module to affect these changes.  Francois Desarmenien, the author of
# Parse::Yapp, is expected to merge these changes into a new release
# some time soon.  If you have a newer version of Parse::Yapp and it 
# supports the '-t <filename>' option then you're probably OK with the
# version you've got and don't need to apply the patch.
