 In this example the function \fBStartTimeCallback\fR will be called
 each time the string \fBCLOCK Start time=(.*)\fR will be emitted on
 the bus.
+There is a special syntax for specifying numeric interval, in this case

+Note that due to the regexp generator limitation (which will perhaps be raised eventually)
