+X.TH GROUPMEMS 8
+X.SH NAME
+groupmems \- Administer members of a user's primary group
+X.SH SYNOPSIS
+X.B groupmems
+\fB-a\fI user_name \fR |
+\fB-d\fI user_name \fR |
+\fB-l\fR |
+\fB-D\fR |
+[\fB-g\fI group_name \fR]
+X.SH DESCRIPTION
+The \fBgroupmems\fR utility allows a user to administer their own
+group membership list without the requirement of superuser privileges.
+The \fBgroupmems\fR utility is for systems that configure its users to
+be in their own name sake primary group (i.e., guest / guest).
+X.P
+Only the superuser, as administrator, can use \fBgroupmems\fR to alter
+the memberships of other groups.
+X.IP "\fB-a \fIuser_name\fR"
+Add a new user to the group membership list.
+X.IP "\fB-d \fIuser_name\fR"
+Delete a user from the group membership list.
+X.IP "\fB-l\fR"
+List the group membership list.
+X.IP "\fB-D\fR"
+Delete all users from the group membership list.
+X.IP "\fB-g \fIgroup_name\fR"
+The superuser can specify which group membership list to modify.
+X.SH SETUP
+The \fBgroupmems\fR executable should be in mode \fB2770\fR as user \fBroot\fR
+and in group \fBgroups\fR.   The system administrator can add users to
+group groups to allow or disallow them using the  \fBgroupmems\fR utility
+to manager their own group membership list.
