-    <warning>
-      <p>This module is deprecated and will be removed in Erlang/OTP 18.</p>
-    </warning>
-    <p>This (experimental) module implements process groups. A process
-      group is a group of processes that can be accessed by a common
-      name. For example, a group named <c>foobar</c> can include a set
-      of processes as members of this group and they can be located on
-      different nodes.</p>
-    <p>When messages are sent to the named group, all members of
-      the group receive the message. The messages are serialized. If
-      the process <c>P1</c> sends the message <c>M1</c> to the group,
-      and process <c>P2</c> simultaneously sends message <c>M2</c>, then
-      all members of the group receive the two messages in the same
-      order. If members of a group terminate, they are automatically 
-      removed from the group.</p>
-    <p>This module is not complete. The module is inspired by the ISIS
-      system and the causal order protocol of the ISIS system should 
-      also be implemented. At the moment, all messages are serialized
-      by sending them through a group master process.</p>
