+Gproc message broadcast server
+This module is used to support gproc:bcast(Key, Msg).
+
+__Behaviours:__ [`gen_server`](gen_server.md).
+
+__Authors:__ Ulf Wiger ([`ulf@wiger.net`](mailto:ulf@wiger.net)).<a name="description"></a>
+
+##Description##
+
+
+gproc:bcast/2 allows for e.g. distributed publish/subscribe, without
+having to resort to global property registration.
+To ensure that erlang's message ordering guarantees are kept, all sends
+are channeled through a broadcast server on each node.<a name="index"></a>
