+    <title>DESCRIPTION</title>
+    <para>
+      The <command>chgpasswd</command> command reads a list of group name
+      and password pairs from standard input and uses this information to
+      update a set of existing groups. Each line is of the format:
+    </para>
+    <para>
+      <emphasis remap='I'>group_name</emphasis>:<emphasis
+      remap='I'>password</emphasis>
+    </para>
+    <para>
+      By default the supplied password must be in clear-text, and is
+      encrypted by <command>chgpasswd</command>.
+    </para>
+    <para>
+      The default encryption algorithm can be defined for the system with
+      the <option>ENCRYPT_METHOD</option> variable of <filename>/etc/login.defs</filename>,
+      and can be overwritten with the <option>-e</option>,
+      <option>-m</option>, or <option>-c</option> options.
+    </para>
+    <para>
+      This command is intended to be used in a large system environment
+      where many accounts are created at a single time.
