# Given an input file perly.y, run bison on it and produce
# the following output files:
#
# perly.h	standard bison header file with minor doctoring of
#		#line directives plus adding a #ifdef PERL_CORE
#
# perly.tab	the parser table C definitions extracted from the bison output
#		plus an extra table generated by this script.
#
# perly.act	the action case statements extracted from the bison output
#
# Note that perly.c is *not* regenerated - this is now a static file which
# is not dependent on perly.y any more.
#
# If a filename of the form foo.y is given on the command line, then
# this is used instead as the basename for all the files mentioned
# above.
#
# Note that temporary files of the form perlytmp.h and perlytmp.c are
# created and then deleted during this process
#
# Note also that this script is intended to be run on a UNIX system;
# it may work elsewhere but no specific attempt has been made to make it
# portable.
