=head1 NAME
efa - unofficial efa.vrr.de command line client
=head1 SYNOPSIS
=over
=item B<efa> B<--from> I<city> I<stop> B<--to> I<city> I<stop> [ I<additional options> ]
=item B<efa> [ I<options> ] I<from-city> I<from-stop> [ I<via-city> I<via-stop> ] I<to-city> I<to-stop>
=back
=head1 DESCRIPTION
B<efa> is a command line client for the L<http://efa.vrr.de> web interface.
It sends the specified information to the online form and displays the results
=head1 OPTIONS
=over
=item B<--from> I<city> I<stop>
Departure place
=item B<--to> I<city> I<stop>
Arrival place
=item B<--via> I<city> I<stop>
Travel via this place
=item B<--from-type>, B<--to-type>, B<--via-type> I<type>
Designate type of the I<stop> for from/to/via.
Possible I<type>s: B<stop> (default), B<address>, B<poi> (point of interest)
=item B<--time>|B<--depart> I<hh>:I<mm>
Journey start time
=item B<--arrive> I<hh>:I<mm>
Journey end time (overrides --time/--depart)
=item B<--date> I<dd>.I<mm>.[I<yyyy>]
Journey date
=item B<--bike>
Choose connections where you can take a bike with you
=item B<--exclude> I<transports>
Exclude I<transports> (comma separated list).
Possible transports: zug, s-bahn, u-bahn, stadtbahn, tram, stadtbus, regionalbus,
schnellbus, seilbahn, schiff, ast, sonstige
=item B<--max-change> I<number>
Print connections with at most I<number> interchanges
=item B<--prefer> I<type>
Prefer connections of I<type>:
=over
=item * speed (default)
The faster, the better
=item * nowait
Prefer connections with less interchanges
=item * nowalk
Prefer connections with less walking (at interchanges)
=back
=item B<--proximity>
Take stops close to the stop/start into account and possibly use them instead
=item B<--restrict> I<type>
Only accept connections using trains of type I<type>, where I<type> may be:
=over
=item * local (default)
only take local trains ("Verbund-/Nahverkehrslinien"). Slow, but the cheapest
method if you're not travelling long distance
=item * ic
All trains except ICE
=item * ice
All trains
=back
=item B<--walk-speed> I<speed>
Set your walking speed to I<speed>.
Accepted values: normal (default), fast, slow
=item B<--ignore-info> [ I<regex> ]
Ignore additional information matching I<regex> (default: /Fahrradmitnahme/).
If I<regex> is not supplied, removes the default regex (-> nothing will be ignored)
=item B<--debug>
Display debug information (additional post requests sent to the site,
raw items received from the site)
=item B<--post> I<key>=I<value>
Add I<key> with I<value> to the HTTP POST request sent to the EFA server.
This can be used to use setting B<efa> does not yet cover, like
C<--post lineRestriction=400> to also show IC and ICE trains.
Note that B<--post> will be overridden by the standard efa options, such as
B<--time>.
