status on jquery compatibility with rails?

I haven't been able to find any recent threads on the compatibility
between jquery and prototype and I was wondering if anyone knows
anything about this. In a screencast I watched, it was mentioned that
there is now a compatibility layer that exists, but I haven't been
able to find any documentation on that.

Jrails is a plugin for Rails, and jquery has a new "nice mode" to play
nice with Prototype. See here:

J Deville

Jquery is compatible with prototype by using jQuery.noConflict() in
your javascript file (application.js).
