/**
* 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.
