7#
8# Required variables:
9#	NETBSDSRCDIR	top level of src tree (set by <bsd.own.mk>)
10#	CRUNCHBIN	name of crunchgen(1)ed binary
11#	LISTS		list file(s) to use
12#	IMAGEDEPENDS	depends for ${IMAGE}
13#	IMAGEENDIAN	endianness of ${IMAGE}
14#	IMAGESIZE	size of ${IMAGE}
15#	MTREECONF	mtree specfiles to use to build a master specfile
16#
17# Optional variables:
18#	IMAGE		name of target image
19#	IMAGEPOSTBUILD	operation to run on ${IMAGE} ${.TARGET} after its built
20#			(if this returns non zero, ${.TARGET} is removed)
21#	DESTDIR		destination directory
22#	MAKEFS_FLAGS	extra options to ${MAKEFS}
23#	PARSELISTENV	environment variables to set for parselist.awk
24#	WORKDIR		directory to build image in to 
25#	IMAGETAR	tar.gz file to create containing ${IMAGE}'s contents
26#
27#	IMAGE_RELEASEDIR	where to install ${IMAGE}.gz
28#	IMAGETAR_RELEASEDIR	where to install ${IMAGETAR}
