db-iris - Interface to the DeutscheBahn online departure monitor
=head1 SYNOPSIS
B<db-iris> [B<-fV>] [B<-d> I<date>] [B<-t> I<time>] [B<-v> I<station>]
I<station>
=head1 VERSION
version 0.00
=head1 DESCRIPTION
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.
=head1 OPTIONS
=over
=item B<-d>, B<--date> I<date>
Request results for I<date> in dd.mm. oder dd.mm.YYYY format. Note that only
slight (a few hours max) deviations from the current time are supported by the
IRIS backend, larger ones will not return data.
=item B<-f>, B<--full-route>
Show the entire route of all trains (both before and after I<station>).
=item B<-t>, B<--time> I<time>
Request results for I<time> in HH:MM oder HH:MM:SS format. Note that only
slight deviations (a few hours max) from the current time are supported by the
IRIS backend, larger ones will not return data.
=item B<-v>, B<--via> I<viastation>
Only show trains serving I<viastation> after I<station>.
=item B<-V>, B<--version>
Show version information.
