+sub debug_timer_start {

+
+    $help = <<'HELP';
+This procedure starts a timer, measuring the elapsed time since the call.
+Each call to this procedure should be matched by a call to
+gimp_debug_timer_end(), which returns the elapsed time.
+
+If there is already an active timer, it is not affected by the call, however, a
+matching gimp_debug_timer_end() call is still required.

+This procedure stops the timer started by a previous gimp_debug_timer_start()
+call, and prints and returns the elapsed time.
+
+If there was already an active timer at the time of corresponding call to
+gimp_debug_timer_start(), a dummy value is returned.
