# Implements the Ruby Stomp client as a queue type within the Puppet::Indirector::Queue::Client
# registry, for use with the <tt>:queue</tt> indirection terminus type.
#
# Looks to <tt>Puppet[:queue_source]</tt> for the sole argument to the underlying Stomp::Client constructor;
# consequently, for this client to work, <tt>Puppet[:queue_source]</tt> must use the Stomp::Client URL-like
# syntax for identifying the Stomp message broker: <em>login:pass@host.port</em>
