+These options take zero or more usernames as parameters and perform the

+If the config file is not specified, the B<-srpvfile> can be used to
+just specify the file to operate on.
+
+The B<-userinfo> option specifies additional information to add when
+adding or modifying a user.
+
+The B<-gn> flag specifies the B<g> and B<N> values, using one of
