  16 # generate mtree style manifest supported by makefs in FreeBSD

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