-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.
