# +INFO_FILES - info file registration management script
#
# Usage: ./+INFO_FILES ADD|REMOVE [metadatadir]
#
# This script supports two actions, ADD and REMOVE, that will add or
# remove entries for info files from the package associated with
# <metadatadir> from the info index files (the "dir" file in the
# same directory as the info files).
#
# Lines starting with "# INFO: " are data read by this script that
# name the info files and directory containing the "dir" index that will
# that will be updated.  If the directory is not specified, then the
# "dir" index is assumed to be in the same directory as the info file.
#
#	# INFO: /usr/pkg/info/bar.info /usr/pkg/info
#	# INFO: /usr/pkg/info/baz.info /usr/pkg/info
#
# For each INFO entry, if the path is relative, that it is taken to be
# relative to ${PKG_PREFIX}.
