# Descrip.MMS -- Makefile for building GNU Awk on VMS with VAXC and MMS.
#
# usage:
#  $ MMS /Description=[.vms]Descrip.MMS gawk
#
# gawk.exe :
#	You'll need to modify this Makefile to use gcc or vaxc v2.x rather
#	than vaxc v3.x.  Change the CFLAGS macro definition (move '#' from
#	beginning of 2nd alternative to beginning of 1st), and also perhaps
#	enable the following ".first" rule and its associated action.  For
#	GNU C, change the LIBS macro definition.
#
# awktab.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 "awktab.c" has its modification date later
#	than the date of "awk.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.
