+ *
+ * xml_producer.cpp
+ *
+ * This is one of three programs used to implement XML-based content
+ * routing in C++.
+ *
+ * declare_queues.cpp
+ *
+ * Creates a queue named "message_qaueue" on the broker,
+ * declares an XML Exchange, subscribes the queue to the XML
+ * Exchange using an XQuery in the binding, then exits.
+ *
+ * xml_producer.cpp (this program)
+ *
+ * Publishes messages to the XML Exchange.
+ *
+ * listener.cpp
+ *
+ * Reads messages from the "message_queue" queue.
