Deploying Rails on 10.5

This may be a lame question, but...

Assuming I want to use the 10.5 built-in Rails "stuff" (ruby, rails,
mongrel), has 10.5 prescribed any particular locations/structure for
Rails projects? I'm thinking of config files for mongrel clusters, where
apps go, etc. Apple usually prescibes some buckets to put things in, but
I'm having a hard time finding any info for Rails. Something akin to the
/Library/WebServer/Documents bucket for generic web stuff.

Certainly I can make up my own organization like I have done on 10.4,
just wondering if there's a "new way" for 10.5?
