  15 #
  16 # This script supports two actions, ADD and REMOVE, that will add or
  17 # remove the directories needed by the package associated with
  18 # <metadatadir>.  The CHECK-ADD action will check whether any directories
  19 # needed by the package are missing, and print an informative message
  20 # noting those directories.  The CHECK-REMOVE action will check whether
  21 # any directories needed by the package still exist, and print an
  22 # informative message noting those directories.  The CHECK-ADD and
  23 # CHECK-REMOVE actions return non-zero if they detect either missing
  24 # or existing directories, respectively.  The PERMS action will correct
  25 # any ownership or permission discrepancies between the existing
  26 # directories and the data in this script, and the CHECK-PERMS action
  27 # will check whether any directories have the wrong ownership or
  28 # permission and print an informative message noting those directories.
  29 # The CHECK-PERMS action will return non-zero if it detects directories
  30 # with wrong ownership or permissions.
  31 #
  32 # Lines starting with "# DIR: " are data read by this script that
  33 # name the directories that this package requires to exist to function
  34 # correctly, e.g.
  35 #
  36 #       # DIR: /etc/foo m
  37 #       # DIR: /var/log/foo/tmp mo 0700 foo-user foo-group
  38 #       # DIR: share/foo-plugins fm
  39 #
  40 # For each DIR entry, if the directory path is relative, then it is taken
  41 # to be relative to ${PKG_PREFIX}.
  42 #
  43 # The second field in each DIR entry is a set of flags with the following
  44 # meanings:
  45 #
  46 #       f       ignore ${PKG_CONFIG}
  47 #       m       create (make) the directory when ADDing
  48 #       o       directory is owned by the package
