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.
