#
# +SHELL - shell registration script
#
# Usage: ./+SHELL ADD|REMOVE [metadatadir]
# ./+SHELL CHECK-ADD|CHECK-REMOVE [metadatadir]
#
# This script supports two actions, ADD and REMOVE, that will add or
# remove shell paths from the shell database in /etc/shells. The
# CHECK-ADD action will check whether shell paths provided by the
# package are missing from the shell database, and print an informative
# message noting those shell paths. The CHECK-REMOVE action will check
# whether shell paths provided by the package are still present in the
# shell database, and print an informative message noting those shell
# paths. The CHECK-ADD and CHECK-REMOVE actions return non-zero if
# they detect either missing or existing paths, respectively.
#
# Lines starting with "# SHELL: " are data read by this script that
# name the shell paths that should be added or removed from the shell
# database. If the path is relative, then it is taken to be relative
# to ${PKG_PREFIX}.
#
# # SHELL: bin/pdksh
