+=head1 NAME
+
+db-ris - Interface to the DeutscheBahn online departure monitor
+
+=head1 SYNOPSIS
+
+B<db-ris> [B<-a>] [B<-d> I<date>] [B<-L>] [B<-m> I<motlist>] [B<-t> I<time>]
+[B<-v> I<via>] I<station>
+
+=head1 VERSION
+
+version 1.02
+
+=head1 DESCRIPTION
+
+db-ris is an interface to the DeutscheBahn departure monitor
+available at L<http://reiseauskunft.bahn.de/bin/bhftafel.exe/dn>.
+
+It requests all departures at I<station> (optionally filtered by date, time,
+route and means of transport) and lists them on stdout, similar to the big
+departure screens installed at most main stations.
+
+=head1 OPTIONS
+
+=over
+
+=item B<-a>, B<--arrivals>
+
+Show arrivals instead of departures, including trains ending at the specified
+station. Note that this causes the output to display the start instead of
+the end station and B<-f> to list all stops between start end
+I<station>, not I<station> and end.
+
+=item B<-d>, B<--date> I<dd>.I<mm>.I<yyyy>
+
+Date to list departures for. Default: today.
+
+=item B<-f>, B<--full-route>
+
+Display complete routes (including arrival times) of all trains.
+
+=item B<-l>, B<--lang> B<d>|B<e>|B<i>|B<n>
+
+Set language used for additional information. Supports B<d>eutsch (default),
+B<e>nglish, B<i>talian and dutch (B<n>).
+
+=item B<-L>, B<--ignore-late>
+
+Do not display delayed trains.
+
+=item B<-m>, B<--mot> I<motlist>
+
+Comma-separated list of modes of transport to show/hide. Accepts the following
+argements:
+
+ ice InterCity Express trains
+ ic_ec InterCity / EuroCity trains
+ d InterRegio and similar
+ nv "Nahverkehr", RegionalExpress and such
+ s S-Bahn
+ bus
+ ferry
+ u U-Bahn
+ tram
+
+You can prefix an argument with "!" to hide it. The default is C<<
+ice,ic_ec,d,nv,s >>. Note that B<-m> does not replace the default, so if you
+only want to see S-Bahn and U-Bahn departures, you'd have to use C<< -m
+!ice,!ic_ec,!d,!nv,u >>.
+
+=item B<-t>, B<--time> I<hh>:I<mm>
+
+Time to list departures for. Default: now.
+
+=item B<-v>, B<--via> I<regex>
+
+Only display trains whose route (all stations between the current stop and the
+destination) matches the perl regular expression I<regex>. The match is not
+case-sensitive. Use '^regex$' to match a full string, but be aware that this
+may not work as expected.
+
+=item B<-V>, B<--version>
+
+Show version information.
+
+=back
+
+=head1 EXIT STATUS
+
+Zero unless things went wrong.
+
+=head1 CONFIGURATION
+
+None.

+
+=head1 BUGS AND LIMITATIONS
+
+There are a few character encoding problems (most notably, B<--via> does not
+understand UTF-8 umlauts).
