- # This file makes Haml work with Rails
- # by monkeypatching the core template-compilation methods.
- # This is necessary for versions <= 2.0.1 because the template handler API
- # wasn't sufficiently powerful to deal with caching and so forth.
- # This module refers to the ActionView module that's part of Ruby on Rails.
- # Haml can be used as an alternate templating engine for it,
- # and includes several modifications to make it more Haml-friendly.
- # The documentation can be found
- # here[http://rubyonrails.org/api/classes/ActionView/Base.html].
