#
# Documentation release building.  These are used to create
# distributions of the documentation files only.  These recipes are
# intended to mimic src/release/Makefile; the principal difference is
# that much of the complexity brought about by the chroot environment
# is unneeded.
#
DOC_PREFIX?=	${.CURDIR}/..

HOSTNAME?=	/bin/hostname
MKISOFS?=	mkisofs
TAR?=		/usr/bin/tar
TOUCH?=		/usr/bin/touch

#
# Targets:
#
# release	Create a clean build of the documentation files,
#		obeying the usual specifications such as FORMATS=,
#		DOC_LANG=, etc.
#
# rerelease	Similar to release, except that existing documentation
#		renderings are preserved and installed.
#
# Configuration variables:
#
# BUILDNAME	Identification string to be placed in BUILDNAME file
#		in the top directory of the release.
#
# DOCROOTDIR	Top directory to use for document release building.
#		This directory need not exist, and will be created
#		if necessary.  This variable MUST be defined.
#
# MAKE_ISOS	If defined, this will enable creation of an ISO image
#		from the document release.  Creation of ISO images
#		requires a mkisofs binary in the invoking user's path.
#
DATE!=		date +%Y%m%d
BUILDNAME?=	${DATE}

#
# Set defaults for FORMATS and DOC_LANG.  To preserve POLA, these
# should be reflect the defaults.
#
FORMATS?=	html
DOC_LANG?=	en_US.ISO8859-1

#
# Miscellaneous but mandatory options for the build get set here.
# The Japanese translation team has a set of manual pages; we turn
# these off (at least for now) because we have not worked their
# install target into our scheme.
