A simple wrapper for jasny's fork of twitter's bootstrap which can be found here.
Unlike rails-jasny-bootstrap-extension, this actually works.
Note that this is just the extension, not the entire fork of jasny's bootstrap. This means you will need to use this gem in conjucntion with [compass-twitter-bootstrap] (https://github.com/vwall/compass-twitter-bootstrap) or twitter-bootstrap-rails
Install the gem
gem install jasny_bootstrap_extension_rails
Add it to your Gemfile
gem 'jasny_bootstrap_extension_rails'
Bundle install
bundle install
In your application.js
//= require jasny-bootstrap
In your application.css
*= require jasny-bootstrap
And if you also want jasny's responsive
*= require jasny-bootstrap-responsive
