Yes we can.

Add to your Gemfile

gem “authlogic”, :git => “git://github.com/odorcicd/authlogic.git”, :branch => “rails3”

Install the gem with

bundle install

… and start generating as follows

rails generate authlogic:session user_session

I think that Rails Plugins needs some UI improvements…
I can’t search for text that Google finds, because it could be into some hidden div (like comments).
