+# +USERGROUP - users and groups management script
+#
+# Usage: ./+USERGROUP ADD|REMOVE [metadatadir]
+# ./+USERGROUP CHECK-ADD|CHECK-REMOVE [metadatadir]
+#
+# This script supports two actions, ADD and REMOVE, that will add or
+# remove the users and groups needed by the package associated with
+# <metadatadir>. The CHECK-ADD action will check whether any users or
+# groups needed by the package are missing, and print an informative
+# message noting those users and groups. The CHECK-REMOVE action will
+# check whether any users and groups needed by the package still exist,
+# and print an informative message noting those users and groups. The
+# CHECK-ADD and CHECK-REMOVE actions return non-zero if they detect
+# either missing or existing users/groups, respectively.
+#
+# Lines starting with "# USER: " or "# GROUP: " are data read by this
+# script that name the users and groups that this package requires to
+# exist to function correctly, e.g.
+#
+# # USER: foo:foogrp::The Foomister
+# # GROUP: foogrp
+#
+# The USER lines are of the form:
+#
+# user:group[:[userid][:[descr][:[home][:shell]]]]
+#
+# Only the user and group are required; everything else is optional,
+# but the colons must be in the right places when specifying optional
+# bits.
+#
+# The GROUP lines are of the form:
+#
+# group[:groupid]
+#
+# Only the group is required; the groupid is optional.
