20# input looks like
21# MANIFEST= my.mtree
22# for each MANIFEST we have a list of dirs
23# ${MANIFEST}.DIRS += bin sbin usr/bin ...
24# for each dir we have a ${MANIFEST}.SRCS.$dir
25# that provides the absolute path to the contents
26# ${MANIFEST}.SRCS.bin += ${OBJTOP}/bin/sh/sh
27# ${MANIFEST}.SYMLINKS is a list of src target pairs
28# for each file/dir there are a number of attributes
29# UID GID MODE FLAGS
30# which can be set per dir, per file or we use defaults
31# eg.
32# MODE.sbin = 550
33# MODE.usr/sbin = 550
34# MODE.dirs = 555
35# means that sbin and usr/sbin get 550 all other dirs get 555
36# MODE.usr/bin/passwd = 4555
37# MODE.usr/bin.files = 555
38# MODE.usr/sbin.files = 500
39# means passwd gets 4555 other files in usr/bin get 555 and
40# files in usr/sbin get 500
41# STORE defaults to basename of src and target directory
42# but we can use
43# ${MANIFEST}.SRCS.sbin += ${OBJTOP}/bin/sh-static/sh-static
44# STORE.sbin/sh-static = sbin/sh
45#
46# the above is a little overkill but means we can easily adapt to
47# different formats
