I'm curious whether you can define the :as option as a list of roles?
All the examples I have seen only has the :as linked to the single
role :admin.
How would I use this with a roles system?
Say I had a #current_user_roles method available from my Controller or
whatever.

Yes, it worked by inserting the require statements in the
initializers.

OK, it seems it works using autoload, being lazy loaded when accessed.
But what if I want to force it to be loaded when rails starts?
Appending a require 'blip' in application.rb I am told no such file
exists!? Would I have to insert it in an initializer?
# lib/blip.rb
puts "Blip loaded!"

How does the lib folder work in Rails 3?
In Rails 2.x you would add require statements in application.rb, fx:
/lib
blip.rb
# blip.rb
puts "BLIP"
# application.rb

require 'blip'

Yes, for some reason it used to be that you would specify first the

actions of the generated controller.
Now you can only specify controller/model and attributes for some
reason.
