# Makefile for TeX in its various incarnations.  It is appropriate
# for the SAS/C Development System Version 6.x by SAS Institute Inc.
# and was written by Andreas Scherer, March 23, 1995.

# With this SMakefile several different versions of TeX can be
# created (one at a time!).  The standard is No20IniTeX/No20VirTeX.
# It is as close to the Web2C implementation as possible.
