/*
* A simple Hello world program that sends and receives a message
* to and from an AMQP broker. The text content is sent as UTF8
* in "raw" form on the wire (so that it matches the C++ client
* sample).
*
* This program requires that the source queue exists and has
* an explicit or implicit binding to the target. The following
* commands work in the default case:
*
* python qpid-config add queue my_topic_node
* python qpid-config bind amq.topic my_topic_node "*"
*
