  17 # This script supports two actions, ADD and REMOVE, that will add or
  18 # remove the configuration files needed by the package associated with
  19 # <metadatadir>.  The CHECK-ADD action will check whether any files
  20 # needed by the package are missing, and print an informative message
  21 # noting those files.  The CHECK-REMOVE action will check whether
  22 # any files needed by the package still exist, and print an informative
  23 # message noting those files.  The CHECK-ADD and CHECK-REMOVE actions
  24 # return non-zero if they detect either missing or existing files,
  25 # respectively.  The VIEW-REMOVE action will remove from <viewdir> the
  26 # links to the configuration files in <depotdir>.  The PERMS action
  27 # will correct any ownership or permission discrepancies between the
  28 # existing files and the data in this script, and the CHECK-PERMS
  29 # action will check whether any files have the wrong ownership or
  30 # permission and print an informative message noting those files.  The
  31 # CHECK-PERMS action will return non-zero if it detects files with
  32 # wrong ownership or permissions.
  33 #
  34 # Lines starting with "# FILE: " are data read by this script that
  35 # name the files that this package requires to exist to function
  36 # correctly, along with the locations of the example files, e.g.
  37 #
  38 #       # FILE: /etc/bar.conf c /example/bar.conf
  39 #       # FILE: /etc/baz/conf c /example/baz.conf 0600 foo-user foo-group
  40 #
  41 # For each FILE entry, if the file path is relative, then it is taken to
  42 # be relative to ${PKG_PREFIX}.
  43 #
  44 # The second field in each FILE entry is a set of flags with the following
  45 # meaning:
  46 #
  47 #       c       file is copied into place
  48 #       f       ignore ${PKG_CONFIG}
  49 #       r       file is an rc.d script (consider ${PKG_RCD_SCRIPTS})
