<!--l. 12--><p class="noindent" >The actor is the basic structural building block for building systems with ROOM. An actor can be refined hierarchically and
thus can be of arbitrarily large scope. Ports define the interface of an actor. An actor can also have a behavior usually defined
by a finite state machine.
