Stomp is a text-oriented wire protocol for messaging (MOM/MQ/JMS)  
type systems. This library provides two useful interfaces, a low- 
level class, Stomp::Connection, which is a basic protocol  
implementation, and Stomp::Client, which is designed as a higher  
level convenience API. More information is available at http:// 
stomp.codehaus.org/

This library is a client for the Stomp protocol. A couple servers  
exist, the most mature probably being ActiveMQ ( http:// 
activemq.codehaus.org ) and Gozirra ( http://www.germane-software.com/ 
software/Java/Gozirra/ ).

While this release is labeled 1.0.0, it is not highly tested yet, so  
bug reports are much appreciated!

# block will be called for each message received from the destination
c.subscribe "/queue/sample" do |message|
   puts "received: #{message.body} on #{message.headers['destination']}"
end

# send a bunch of stuff  (which we will receive)
for i in 1..5 do
   c.send "/queue/sample", "Hello world #{i}!"
