#	$NetBSD: Makefile,v 1.284 2004/03/08 05:46:44 cgd Exp $
#	from: @(#)Makefile	8.7 (Berkeley) 5/25/95

# Environment variables without default values:
#   DESTDIR must be set before anything in this file will work.
#   RELEASEDIR is where the tarred up stuff for a snapshot or
#	release will be placed.
#
# Environment variables with default values:
#   LOCALTIME will set the default local time for the system you
#	build; it determines what /etc/localtime is symlink'd to.
#   KERNSRCDIR points to kernel source; it is set by default to ../sys,
#	but can be overridden.
#   KERNOBJDIR is the kernel build directory, it defaults to
#	${KERNSRCDIR}/arch/${MACHINE}/compile, but can be overridden.
#   KERNCONFDIR is where the configuration files for kernels are found;
#	default is ${KERNSRCDIR}/arch/${MACHINE}/conf but can be overridden.
#   MKCRYPTO; if not `no', install crypto-related configuration
#   MKSENDMAIL; if not `no', install sendmail configuration
#   MKUNPRIVED; if not `no', allow non-root installs.
#   MKUPDATE; if not `no', don't do a 'make clean' before kernel compile
#
# Targets:
#    distribution: makes a full NetBSD distribution in DESTDIR. If
#	INSTALL_DONE is set, it will not do a `make install.'
#	if DISTRIBUTION_DONE is set, it will not do anything.
#    distrib-dirs: creates an empty NetBSD directory tree in DESTDIR.
#	Called by distribution.
#    snapshot: calls distribution, above, and then tars up the files
#	into a release(7) format in RELEASEDIR/${MACHINE}.
#	Any port-dependent stuff for this target is found in
#	etc.${MACHINE}/Makefile.inc.
#    release: a synonym for `snapshot'

#				are also placed in the binary/kernel
#				area of the release package as
#				netbsd-${kernel}.gz.
#
#	EXTRA_KERNELS		Additional kernels to place in the
#				binary/kernel area of the release
#				package as netbsd-${kernel}.gz, but
#				which are not placed into sets. This
#				allows a port to provide e.g. a netbootable
#				installation kernel containing a ramdisk.
#
#	BUILD_KERNELS		Additional kernels to build which are
#				not placed into sets nor into the
#				binary/kernel area of the release
#				package.  These are typically kernels
#				that are built for inclusion only in
#				installation disk/CD-ROM/tape images.
#
#	A port may also specify KERNEL_SUFFIXES, which is an optional list
#	of filename suffixes for kernels to include in the kernel sets and
#	in the binary/kernel area of the release package (e.g. "netbsd" vs.
#	"netbsd.ecoff" and "netbsd.srec").  It is not an error if kernels
#	with these suffixes do not exist in the kernel build directory.
