# 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.

#

# command.c :

#	Similar to awkgram.c; built from command.y with yacc or bison.

#

# 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.
