ActionController::Base.send :include,

Hi    n one of the pluggin I saw this code Could anybody please tell what does all this mean

ActionController::Base.send :include, helper_name ActionController::Base.helper helper_name ActionView::Helpers::FormBuilder.send :include, helper_name

Thanks in advance Sijo

The first line is including some instance methods into ActionController::Base (from which ApplicationController inherits). The second line then adds helper_name to the list of helpers available to all controllers. The final line does the same thing for the views.
