You will need to start using exchanges. Please see section 3.1.3 of the
AMQP 0-8 specification PDF
(http://jira.amqp.org/confluence/download/attachments/720900/amqp0-8.pdf?version=1)
for information on the kinds of exchanges that are available.

To read from a fanout exchange using Ruby STOMP,

  conn = Stomp::Connection.open('guest', 'guest', 'localhost')
  conn.subscribe('', :exchange => 'myexchange')

To write to a fanout exchange using Ruby STOMP,

  conn.send 'routingkey', 'messagebody', :exchange => 'myexchange'


STOMP provides no facility (yet) for declaring exchanges. You will need
to use an AMQP client library (e.g. the Java one) to declare the
exchanges your application will need.
