+<tag><bf>Description:</bf></tag>
+
+Provides standard Unix <em/nologin/ authentication.  If the file
+<tt>/etc/nologin</tt> exists, only root is allowed to log in; other
+users are turned away with an error message.  All users (root or
+otherwise) are shown the contents of <tt>/etc/nologin</tt>.
+
+<p>
+If the file <tt>/etc/nologin</tt> does not exist, this module succeeds
+silently.
+
+<tag><bf>Examples/suggested usage:</bf></tag>
+
+In order to make this module effective, all login methods should
+be secured by it.  It should be used as a <tt>required</tt>
+method listed before any <tt>sufficient</tt> methods in order to
+get standard Unix nologin semantics.
