 db-iris is an interface to the DeutscheBahn departure monitor
 available at L<https://iris.noncd.db.de/wbt/js/index.html>.
 
-It requests all departures at I<station> and lists them on stdout, similar to
-the big departure screens installed at most main stations. I<station> can be
-a DS100 station code (such as "EE"), a normal station name
-(such as "Essen Hbf" or "Dortmund UniversitE<auml>t"), or an IBNR / european station
-number (such as 8000098). If no exact match is found, B<db-iris> will try to
-find station names similar to I<station>.
-
-An exclamation mark (C<< ! >>) next to a destination indicates that at least
-one stop on the train's route has been canceled. Use B<-oc> to see the canceled
-stops.  An exclamation mark next to a platform indicates that it is not the
-scheduled one.
