# Descrip.MMS -- Makefile for building GNU awk on VMS.
#
# usage:
# $ MMS /Description=[.vms]Descrip.MMS gawk
# possibly add `/Macro=("GNUC=1")' to compile with GNU C,
# or add `/Macro=("GNUC=1","DO_GNUC_SETUP=1")' to compile with GNU C
# on a system where GCC is not installed as a defined command,
# or add `/Macro=("VAXC=1")' to compile with VAX C,
# or add `/Macro=("VAXC=1","CC=cc/VAXC")' to compile with VAX C on
# a system which has DEC C installed as the default compiler.
#
# gawk.exe :
# This is the default target. DEC C has become the default compiler.
#
# awkgram.c :
# If you don't have bison but do have VMS POSIX or DEC/Shell,
# change the PARSER and PASERINIT macros to use yacc. If you don't
# have either yacc or bison, you'll have to make sure that the
# distributed version of "awkgram.c" has its modification date later
# than the date of "awkgram.y", so that MMS won't try to build that
# target. If you use bison and it is already defined system-wide,
# comment out the PARSERINIT definition.
#
# install.help :
# You can make the target 'install.help' to load the VMS help text
# into a help library. Modify the HELPLIB macro if you don't want
# to put entry into the regular VMS library. (If you use an alternate
# help library, it must already exist; this target won't create it.)
#
# gawk.dvi :
# If you have TeX, you can make the target 'gawk.dvi' to process
# _The_GAWK_Manual_ from gawk.texi. You'll need to use a device
# specific post-processor on gawk.dvi in order to get printable data.
# The full output is approximately 325 pages.
