So after bother Justin for a new moments (well 57 moments) it seems that the document we were looking for was never completed (Justin wanted to make things pretty and easy first).
We are going to start up on the IRC channel and work through making a "helloworld.war" now, and then post the notes on the wiki site. If anyone else wants to join, talk shop, or wonder at the config system (or its new optional catalog substitute) then you are welcome to join us.
To be clear we are going to document how things work now, Justin may make things easier later.
Cheers,
Jody
