Documentation for recorded_session

Hi

I'm trying to get behind how to write my own generators. For this I started to analyze the code of some generators, e.g. restful_authentication and there's one functon I haven't found a documentation for: recorded_session

I have seen some of the functions which are provided through recorded_session but I would like to read the documentation for it to get an overview over the whole functionality which is provided by recorded_session.

So, has anybody a link to the documentation of recorded_session or to an other site where the function is explained? I've already searched the Rails documentation and on Google, but I haven't found anything.

Thanks Mato
