Role-based access control (RBAC)
Don't know if it should be a rails engine or a simple Gem for use on non-Rails projects.
Its going to be a Gem. Not sure as to what its name will be. Not sure but it might even end up as a plugin for CanCanCan.
Add this line to your application's Gemfile:
gem 'rbac_engine'
And then execute:
$ bundle
Or install it yourself as:
$ gem install rbac_engine
