module AbstractController
# # URL For
#
# Includes `url_for` into the host class (e.g. an abstract controller or
# mailer). The class has to provide a `RouteSet` by implementing the `_routes`
# methods. Otherwise, an exception will be raised.
#
# Note that this module is completely decoupled from HTTP - the only requirement
# is a valid `_routes` implementation.
