# The include file <bsd.sgml.mk> handles installing sgml documents.
# <bsd.prog.mk> includes the file named "../Makefile.inc" if it exists,
# as well as the include files <bsd.dep.mk> and <bsd.obj.mk>.
#
#
# +++ variables +++
#
# DISTRIBUTION	Name of distribution. [doc]
#
# FORMATS 	Indicates which output formats will be generated
#               (ascii, html, latex, latin1, nroff). [html latin1 ascii]
#
# LPR		Printer command. [lpr]
#
# NOSGMLCOMPRESS	If you do not want SGML formatted documents
#		be compressed when they are installed. [yes]
#
# SCOMPRESS_CMD	Program to compress SGML formatted documents. Output is to
#		stdout. [${COMPRESS_CMD}]
#
# SGMLFLAGS	Flags to sgmlfmt. [${SGMLOPTS}]
#
# SGMLFMT	Format sgml files command. [sgmlfmt]
#
# Variables DOCOWN, DOCGRP, DOCMODE, DOCDIR, DESTDIR, DISTDIR are
# set by other Makefiles (e.g. bsd.own.mk)
#
#
# +++ targets +++
#
#	all:
#		Converts sgml files to the specified output format
#		(see ${FORMATS}).
#
#	distribute:
# 		This is a variant of install, which will
# 		put the stuff into the right "distribution".
#
#	install:
#		Install formated output.
#
#	print:
#		Print formated output.
