ActionController::Base.send :include, etc

Rails

Hi
In one of the method say
require_helpers

i have the code
helper_constant = SomeHelper
ActionController::Base.send :include, helper_constant
ActionView::Base.send :include, helper_constant
ActionView::Helpers::FormBuilder.send :include, helper_constant

 And I did not understand what actually the above does?

and see following codes:

module MyTools
def run(*args)
puts “let #{args.join(’ ')} run”
end
end

class TryTools
#include MyTools
def initialize()
self.class.send :include,MyTools
end
end

c=TryTools.new
c.run(“me”)
