Map::Tube::KoelnBonn - Interface to the Koeln-Bonn (Cologne/Bonn) area U- and S-Bahn and tram maps

=cut

=head1 SYNOPSIS

    use Map::Tube::KoelnBonn;
	my $tube = Map::Tube::KoelnBonn->new( );

	my $route = $tube->get_shortest_route( 'Wurzerstr.', 'Plittersdorf' );

    print "Route: $route\n";

=head1 DESCRIPTION

This module allows to find the shortest route between any two given tube
stations in Köln and Bonn. In fact, underground, tramway, and S-Bahn lines
are covered for the wider Köln-Bonn area (VRS).
All interesting methods are provided by the role L<Map::Tube>.

=head1 METHODS

=head2 CONSTRUCTOR

    use Map::Tube::KoelnBonn;
	my $tube = Map::Tube::KoelnBonn->new( );

The only argument, C<xml>, is optional; if specified, it should be a code ref
to a function that returns either the path the XML map file, or a string
containing this XML content. The default is the path to F<koelnbonn-map.xml>
that is a part of this distribution. For further information see L<Map::Tube>.

=head2 xml( )

This read-only accessor returns whatever was specified as the XML source at
construction.

=head1 ERRORS

If something goes wrong, maybe because the map information file was corrupted,
the constructor will die.
