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
