+ module Helpers #:nodoc:
+ # Provides methods for linking an HTML page together with other assets such
+ # as images, javascripts, stylesheets, and feeds. You can direct Rails to
+ # link to assets from a dedicated assets server by setting ActionController::Base.asset_host
+ # in your environment.rb. These methods do not verify the assets exist before
+ # linking to them.
+ #
+ # ActionController::Base.asset_host = "http://assets.example.com"
+ # image_tag("rails.png")
+ # => <img src="http://assets.example.com/images/rails.png" alt="Rails" />
+ # stylesheet_include_tag("application")
