10#	CRUNCHBIN	name of crunchgen(1)ed binary
11#	LISTS		list file(s) to use
12#	IMAGE		name of target image
13#	IMAGEDEPENDS	depends for ${IMAGE}
14#	IMAGEENDIAN	endianness of ${IMAGE}
15#	IMAGESIZE	size of ${IMAGE}
16#	MTREECONF	mtree specfiles to use to build a master specfile
17#
18# Optional variables:
19#	MAKEFS_FLAGS	extra options to ${MAKEFS}
