+/**
+ * topic_publisher.cpp:
+ *
+ * This program is one of three programs designed to be used
+ * together. These programs implement a publish-subscribe example
+ * using the "amq.topic" exchange. In the example multiple listeners
+ * can subscribe to the same queues for TTL messages.
+ * The TTL messages are all ticker price data. Messages are
+ * browsed and therefore shared among the multiple listeners.
+ * Messages timeout using TTL so that they don't stay in the queue
+ * for too long and fill it up.
+ * Local exclusive LVQ are also declared for market data.
+ *
+ * declare_queues.cpp
+ *
+ * Declares several non-exclusive queues bound to the amq:topic exchange
+ *
+ * topic_publisher.cpp
+ *
+ * Sends messages to the "amq.topic" exchange, using the
+ * multipart routing keys for ticker price and market data
+ * Ticker messages are sent using a TTL value.
+ *
+ * topic_listener.cpp (this program)
+ *
+ * Subscribes to non-exclusive queues in NOT_ACQUIRE mode for
+ * ticker price data and declares two LVQs for market data.
+ *
+ * Multiple listeners can be run at the same time.
