Rails documentation XML service

Anyone know if there is a WebService for the Rails Docs and Ruby Docs?
Since i spend most of my coding time digging through the API of rails
and the Corelib i figured i would make it a little easier to use.

To that end, i was wondering if there was an XML service i could connect
to to pull the information and lay it out as needed, or am i going to to
have to do it manually somehow?

Any insights would be appreciated.
