=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.

=item * Class::Accessor(3pm)

=item * DateTime(3pm)

=item * LWP::UserAgent(3pm)

=item * XML::LibXML(3pm)

=head1 BUGS AND LIMITATIONS

There are a few character encoding problems (most notably, B<--via> does not

understand UTF-8 umlauts).

Todo.
