Stomp is a simple text oriented messaging protocol. Stomperl is an implementation of Stomp broker with Erlang. That means performance, scalability, reliability and elegance in concurrent programming are our goals.

Stomperl stole its architecture and initial code base from following articles:

• Building a Non-blocking TCP server using OTP principles
• supervisor の simple_one_for_one を使って echoserver を書き直した - for those who don't understand Japanese: I don't either, and it doesn't matter.

The picture below shows current architecture of Stomperl.
