-// Repeaters are both signals and slots, which are designed as intermediate
-// pass-throughs for signals and slots which don't know about each other (for
-// modularity or encapsulation).  This eliminates the need to declare a signal
-// handler whose sole purpose is to fire another signal.  The repeater connects
-// to the originating signal using the 'repeat' method.  When the repeated
-// signal fires, the repeater will also fire.
