# +FILES - reference-counted configuration file management script
#
# Usage: ./+FILES ADD|REMOVE [metadatadir]
# ./+FILES VIEW-REMOVE depotdir viewdir
# ./+FILES CHECK-ADD|CHECK-REMOVE [metadatadir]
#
# This script supports two actions, ADD and REMOVE, that will add or
# remove the configuration files needed by the package associated with
# <metadatadir>. The CHECK-ADD action will check whether any files
# needed by the package are missing, and print an informative message
# noting those files. The CHECK-REMOVE action will check whether
# any files needed by the package still exist, and print an informative
# message noting those files. The CHECK-ADD and CHECK-REMOVE actions
# return non-zero if they detect either missing or existing files,
# respectively. The VIEW-REMOVE action will remove from <viewdir> the
# links to the configuration files in <depotdir>.
#
# Lines starting with "# FILE: " are data read by this script that
# name the files that this package requires to exist to function
# correctly, along with the locations of the example files, e.g.
#
# # FILE: /etc/bar.conf c /example/bar.conf
# # FILE: /etc/baz/conf c /example/baz.conf 0600 foo-user foo-group
#
# For each FILE entry, if the file path is relative, then it is taken to
# be relative to ${PKG_PREFIX}.
#
# The second field in each FILE entry is a set of flags with the following
# meaning:
#
# c file is copied into place
# f ignore ${PKG_CONFIG}
# r file is an rc.d script (consider ${PKG_RCD_SCRIPTS})
