| // 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. |
