# Makefile for creating mlyacc.sml and base.sml files.
# Created: David Tarditi (tarditi@cs.cmu.edu) 12/4/89
#
# Description:
#   This makefile can create two different files:
#	smlyacc.sml: SML file for ML-Yacc.  It comes in two variants: 
#                     one to create a stand-alone image and one to be run
#                     from the interactive system.
#	base.sml: SML file which must be loaded before any files produced
#		  smlyacc are loaded.  This file contains background
#		  signatures, the polymorphic parser structure, and the
#		  functors to join lexers and parsers.
#
#		  It comes in two variants: one with a vanilla parser
#		  and another with an error-correcting parser
#
#    The makefile does not have an entry to create base.sml -- the user
#    must explicitly do this.  This forces the user to consciously choose
#    the parser to be created.

# create smlyacc file from parts
