/**
 *  fanout_producer.cpp:
 *
 *  This program is one of two programs designed to be used
 *  together.
 *
 *    fanout_producer.cpp (this program):
 *
 *      Publishes messages to the "amq.fanout" exchange.
 *
 *    listener.cpp
 *
 *      Creates a private queue, binds it to the "amq.fanout"
 *      exchange, and reads messages from its queue as they
 *      arrive. Messages sent before the listener binds the queue are
 *      not received.
 *
 *      Multiple listeners can run at the same time.
 *
