/**
 * This class provides one-shot-and-forget audio playing. You will never
 * know if what you wanted to play really got played.
 *
 * It doesn't require linking any special libraries, as it operates over
 * DCOP. In the current implementation, it only indirectly communicates
 * with the aRts soundserver, using knotify as DCOP -> MCOP bridge.
 *
 * Due to that fact, if you need "fast" response times, more control or
 * feedback, use the MCOP interfaces rather than this.
 *
 * An example of using this class is:
 *
 * <pre>
 *   KAudioPlayer::play("/var/share/foo.wav");
 * </pre>
 *
 * If you want to use signals & slots, you can do something like:
 *
 * <pre>
 *   KAudioPlayer player("/var/share/foo.wav");
 *   connect(&button, SIGNAL(clicked()), &player, SLOT(play()));
 * </pre>
