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