#
# Top level makefile. Instructions are included here and in the README file.
#
# First save a copy of this file. Then adjust the following definitions (all
# come immediatedly after the initial block of comments):
#
#     MAKE	where make lives
#
#     MAKEFILE	name of this file - for recursive make calls. Must change
#		if you rename this file.
#
#     SYSTEM	best match for your version of Unix. Current choices for
#		SYSTEM are:
#
#			SYSV	- System V
#			V9	- Ninth Edition
#			BSD4_2	- Berkeley (eg. Sun)
#
#		Controls conditional compilation in a few places.
#
#     VERSION	refers to the Version of the DWB package
#
#     GROUP	group assigned to all installed files
#
#     OWNER	owner of everything that's installed
#
#     HOSTDIR	hostresident font directory for PostScript printers. Only
#		used in the font download program.
#
#     FONTDIR	width table directory - for troff and dpost
#
#     MAN1DIR	command manpages. A command and its manpage are installed
#		together - there's no easy way to avoid it. Setting MAN1DIR
#		to an existing temporary directory (e.g. /tmp) means an
#		install will work but manpages won't go anywhere permanent.
#		MAN1DIR must already exist - it will not be created during
#		an install.
#
#     POSTBIN	where most PostScript support programs go. dpost and picpack
#		are the exceptions.
#
#     POSTLIB	prologues and miscellaneous PostScript files. Primarily for
#		the programs that live in POSTBIN.
#
#     CFLGS	common compiler options - used to build CFLAGS in the low
#		level makefiles. CFLGS and LDFLGS are best set on the make
#		command line.
#
#     LDFLGS	common link editor options - used to build LDFLAGS in the
#		low level makefiles. LDFLGS and CFLGS are best set on the
#		make command line.
#
#     DKHOST	set it to TRUE to compile the DKHOST Datakit support code
#		in postio. Temporarily resets SYSTEM to SYSV if DKHOST is
#		TRUE and SYSTEM is BSD4_2. Ignored if SYSTEM is not SYSV
#		or BSD4_2.
#
#     DKSTREAMS enables streams based DKHOST support in postio when DKHOST
#		is TRUE and SYSTEM is SYSV or BSD4_2. Choices are TRUE,
#		FALSE, or a stream module name (e.g. dknetty or dkty). TRUE
#		selects dknetty. Newer systems may expect dkty.
#
#     ROUNDPAGE	must only be set to TRUE or FALSE. TRUE means translators
#		include code that maps clipping path dimensions into known
#		paper sizes.
#
#     TARGETS	the default list of what's built by make. Each target must
#		be the name of a source directory. A target that names a
#		non-existent source directory is ignored. Setting TARGETS
#		on the make command line overrides the default list.
#
# Source files must be updated whenever this file changes. If you change any
# definitions type,
#
#	make -f postscript.mk changes
#
# to update the source files, man pages, and low level makefiles.
#
# To build (but not install) the default package (i.e. everything named by
# TARGETS) type,
#
#	make -f postscript.mk all
#
# The recommended way to build and install the package is,
#
#	make -f postscript.mk all install
#
# Although you'll likely have to be root for the install to work.
#
# After the package is installed use,
#
#	make -f postscript.mk clobber
#
# to delete binary files and compiled programs from the source directories.
#
# Set TARGETS on the command line to select part of the package. For example,
#
#	make -f postscript.mk TARGETS="dpost devpost" all install
#
# builds and installs dpsot and the PostScript font tables. Quotes hide white
# space from the shell.
