=head1 NAME
Travel::Status::DE::IRIS::Stations - Station name to station code mapping
=head1 SYNOPSIS
use Travel::Status::DE::IRIS::Stations;
my $name = 'Essen Hbf';
my @stations = Travel::Status::DE::IRIS::Stations::get_station_by_name(
$name);
if (@stations < 1) {
# no matching stations
}
elsif (@stations > 1) {
# too many matches
}
else {
printf("Input '%s' matched station code %s (as '%s')\n",
$name, @{$stations[0]});
}

version 0.00
=head1 DESCRIPTION
This module contains a mapping of DeutscheBahn station names to station codes.
A station name is a (perhaps slightly abbreviated) string naming a particular
station; a station code is a two to five character denoting a station for the
IRIS web service.
Example station names (code in parentheses) are:
"Essen HBf" (EE), "Aachen Schanz" (KASZ), "Do UniversitE<auml>t" (EDUV).
B<Note:> Station codes may contain whitespace.
=head1 METHODS
=over
=item Travel::Status::DE::IRIS::get_stations
Returns a list of [station code, station name] listrefs lexically sorted by
station name.
=item Travel::Status::DE::IRIS::get_station(I<$in>)
Returns a list of [station code, station name] listrefs matching I<$in>.
If a I<$in> is a valid station code, only one element ([I<$in>, related name])
is returned. Otherwise, it is passed to get_station_by_name(I<$in>) (see
below).
Note that station codes matching is case sensitive and must be exact.
=item Travel::Status::DE::IRIS::get_station_by_name(I<$name>)
Returns a list of [station code, station name] listrefs where the station
name matches I<$name>.
Matching happens in two steps: If a case-insensitive exact match exists, only
this one is returned. Otherwise, all stations whose name contains I<$name> as
a substring (also case-insensitive) are returned.
This two-step behaviour makes sure that not prefix-free stations can still be
matched directly. For instance, both "Essen-Steele" and "Essen-Steele Ost"
are valid station names, but "essen-steele" will only return "Essen-Steele".

yet.
