#delivery(type, &block) ⇒ Object

Specifies which Sprinkle::Actors to use for delivery. Although all actors jobs are the same: to run remote commands on a server, you may have a personal preference. The block you pass is used to configure the actor. For more information on what configuration options are available, view the corresponding Sprinkle::Actors page.
