hafas-m is an interface to HAFAS arrival/departure monitors such as the one

available at L<https://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.

It has three operating modes that depend on the contents of its argument.

=head2 Arrival/Departure Monitor

Show departures (or arrivals) at I<station>, optionally filtered by date, time

and mode of transport. I<station> may be given as a station name or EVA ID.

EVA IDs tend to be similar to, but not always identical with, UIC station

codes. Output format:

=over

=item * scheduled departure (or arrival) time

=item * delay, if known

=item * trip number or line

=item * direction / destination

=item * platform (B<!> indicates a platform change)

=item * expected occupancy of first and second class, if known

=back

Occupancy indicators are, from least occupied to fully booked: B<.> B<o>

B<*> B<!>.

=head2 Location Search

List stations that match I<query> or that are located in the vicinity of

I<lat>B<:>I<lon> geocoordinates with EVA ID and name.

=head2 Trip Details

List intermediate stops of I<journeyID> with arrival/departure time, delay (if

available), occupancy (if available), and stop name.
