+# +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}.
