How to start using Beaker in Django

Question: Could people show or point me toward a complete example or tutorial to start using Beaker in Django?

Information: Since I've read about problems in database connection with django ORM here I've decided to replace Django's ORM with sqlalchemy, but that means I can't use sessions from Django.

Beaker looks promising to me, but I don't know where to start. The Beaker documentation left me with many questions such as:

• What is WSGIAPP?
• How do I use a Beaker session in my Dj开发者_开发知识库ango view?
• Where is a runnable example?

Could people show or point me toward a complete example or tutorial to start using Beaker in Django?

Note: I'm using Django-1.1.1 and Beaker 1.5

This question is old so I'm not sure if this is still needed, but here is one link: http://seeknuance.com/2010/09/16/multiple-cache-backends-in-django/
