Is AuthenticatedSystem an open source RoR module?

I am looking at this github app, and they have a module named AuthenticatedSystem.

I googled and found a rdoc, 开发者_StackOverflow社区but can't find the source code for the module.

Anyone heard of this? I know there are other authentication modules out there, but I am looking to just learn from this one as it looks simple to me.

Yes, the AuthenticatedSystem module is part of the highly popular restful_authentication plugin:

I hope this helps!
