# generate mtree style manifest supported by makefs in FreeBSD
# input looks like
# MANIFEST= my.mtree
# for each MANIFEST we have a list of dirs
# ${MANIFEST}.DIRS += bin sbin usr/bin ...
# for each dir we have a ${MANIFEST}.SRCS.$dir
# that provides the absolute path to the contents
# ${MANIFEST}.SRCS.bin += ${OBJTOP}/bin/sh/sh
# ${MANIFEST}.SYMLINKS is a list of src target pairs
# for each file/dir there are a number of attributes
# UID GID MODE FLAGS
# which can be set per dir, per file or we use defaults
# eg.
# MODE.sbin = 550
# MODE.usr/sbin = 550
# MODE.dirs = 555
# means that sbin and usr/sbin get 550 all other dirs get 555
# MODE.usr/bin/passwd = 4555
# MODE.usr/bin.files = 555
# MODE.usr/sbin.files = 500
# means passwd gets 4555 other files in usr/bin get 555 and
# files in usr/sbin get 500
# STORE defaults to basename of src and target directory
# but we can use
# ${MANIFEST}.SRCS.sbin += ${OBJTOP}/bin/sh-static/sh-static
# STORE.sbin/sh-static = sbin/sh
#
# the above is a little overkill but means we can easily adapt to
# different formats
