-
-=item $result->platform
-
-Returns the platform from which the train will depart / at which it will
-arrive.
-
-=item $result->route
-
-Returns a list of station names the train will pass between the selected
-station and its origin/destination.
-
-=item $result->route_end
-
-Returns the last element of the route.  Depending on how you set up
-Travel::Status::DE::DeutscheBahn (arrival or departure listing), this is
-either the train's destination or its origin station.
-
-=item $result->destination
-
-=item $result->origin
-
-Convenience aliases for $result->route_end.
-
-=item $result->route_interesting([I<max>])
-
-Returns a list of up to I<max> (default: 3) interesting stations the train
-will pass on its journey. Since deciding whether a station is interesting or
-not is somewhat tricky, this feature should be considered experimental.
-
-The first element of the list is always the train's next stop. The following
-elements contain as many main stations as possible, but there may also be
-smaller stations if not enough main stations are available.
-
-In future versions, other factors may be taken into account as well.  For
-example, right now airport stations are usually not included in this list,
-although they should be.
-
-Note that all main stations will be stripped of their "Hbf" suffix.
-
-=item $result->route_raw
-
-Returns the raw string used to create the route array.
-
-Note that cancelled stops are filtered from B<route>, but still present in
-B<route_raw>.
-
-=item $result->route_timetable
-
-Similar to B<route>.  however, this function returns a list of array
-references of the form C<< [ arrival time, station name ] >>.
-
-=item $result->route_info
-
-Returns a string containing information related to the train's route, such as
-"landslide between X and Y, expect delays".
-
-=item $result->time
-
-Returns the arrival/departure time as string in "hh:mm" format.
-
-=item $result->type
-
-Returns the type of this train, e.g. "S" for S-Bahn, "RE" for Regional Express
-or "ICE" for InterCity-Express.

+=head1 NAME
+
+Travel::Status::DE::HAFAS - Interface to HAFAS-based online arrival/departure
+monitors
+
+=head1 SYNOPSIS
+
+	use Travel::Status::DE::HAFAS;
+
+	my $status = Travel::Status::DE::HAFAS->new(
+		station => 'Essen Hbf',
+	);
+
+	if (my $err = $status->errstr) {

+			$departure->time,
+			$departure->line,
+			$departure->destination,
+			$departure->platform,
+		);
+	}
+
+=head1 VERSION
+
+version 1.05
+
+=head1 DESCRIPTION
+
+Travel::Status::DE::HAFAS is an interface to HAFAS-based
+arrival/departure monitors, for instance the one available at
+L<http://reiseauskunft.bahn.de/bin/bhftafel.exe/dn>.
+
+It takes a station name and (optional) date and time and reports all arrivals
+or departures at that station starting at the specified point in time (now if
+unspecified).
+
+=head1 METHODS
+
+=over
+
+=item my $status = Travel::Status::DE::HAFAS->new(I<%opts>)
+
+Requests the departures/arrivals as specified by I<opts> and returns a new
+Travel::Status::DE::HAFAS element with the results.  Dies if the wrong
+I<opts> were passed.
+
+Supported I<opts> are:
+
+=over
+
+=item B<station> => I<station>
+
+The train station to report for, e.g.  "Essen HBf" or
+"Alfredusbad, Essen (Ruhr)".  Mandatory.
+
+=item B<date> => I<dd>.I<mm>.I<yyyy>
+
+Date to report for.  Defaults to the current day.
+
+=item B<language> => I<language>
+
+Set language for additional information. Accepted arguments: B<d>eutsch,
+B<e>nglish, B<i>talian, B<n> (dutch).
+
+=item B<lwp_options> => I<\%hashref>
+
+Passed on to C<< LWP::UserAgent->new >>. Defaults to C<< { timeout => 10 } >>,
+you can use an empty hashref to override it.
+
+=item B<time> => I<hh>:I<mm>
+
+Time to report for.  Defaults to now.
+
+=item B<mode> => B<arr>|B<dep>
+
+By default, Travel::Status::DE::HAFAS reports train departures
+(B<dep>).  Set this to B<arr> to get arrivals instead.
+
+=item B<mot> => I<\%hashref>
+
+Modes of transport to show.  Accepted keys are: B<ice> (ICE trains), B<ic_ec>
+(IC and EC trains), B<d> (InterRegio and similarly fast trains), B<nv>
+("Nahverkehr", mostly RegionalExpress trains), B<s> ("S-Bahn"), B<bus>,
+B<ferry>, B<u> ("U-Bahn") and B<tram>.
+
+Setting a mode (as hash key) to 1 includes it, 0 excludes it.  undef leaves it
+at the default.
+
+By default, the following are shown: ice, ic_ec, d, nv, s.
+
+=back
+
+=item $status->errstr
+
+In case of an error in the HTTP request, returns a string describing it.  If
+no error occurred, returns undef.
+
+=item $status->results
+
+Returns a list of arrivals/departures.  Each list element is a
+Travel::Status::DE::HAFAS::Result(3pm) object.
+
+If no matching results were found or the parser / http request failed, returns
+undef.

+
+=item $result->messages
+
+Returns a list of message strings related to this train. Messages usually are
+service notices (e.g. "missing carriage") or detailed delay reasons

+=item $result->train
+
