    WWW::Gazetteer::FallingRain - Find location of world towns and cities

      use WWW::Gazetteer;
      my $g = WWW::Gazetteer::FallingRain->new('calle');
      my @londons = $g->find(UK => 'London');
      my $london = $londons[0];
      print $london->{longitude}, ", ", $london->{latitude}, "\n";
      my $nice = $g->find("Nice", "France")->[0];
      print $nice->{city}, ", ", $nice->{elevation}, "\n";

    A gazetteer is a geographical dictionary (as at the back of an atlas).
    The "WWW::Gazetteer::FallingRain" module uses the information at to return geographical location
    (longitude, latitude, elevation) for towns and cities in countries in
    the world.

    This module is a subclass of "WWW::Gazetteer", so you must use that to
    create a "WWW::Gazetteer::FallingRain" object. Once you have imported
    the module and created a gazetteer object, calling find($country =>
    $town) will return a list of hashrefs with longitude and latitude

      my @londons = $g->find(UK => 'London');
      my $london = $londons[0];
      print $london->{longitude}, ", ", $london->{latitude}, "\n";
      # prints -0.1167, 51.5000

    The hashref for London actually looks like this:

      $london = {
        longitude => "-0.1167",
        latitude  => "51.5000",
        city      => 'London',
        country   => 'UK',
        elevation => "14",

    The city and country values are the same as the ones you used. The
    elevation is elevation above sea level in meters. The longitude and
    latitude are in degrees, ranging from -180 to 180 where (0, 0) is on the
    Prime Meridian and the equator.

    This returns a new WWW::Gazetteer::FallingRain object. It currently has
    no arguments:

      use WWW::Gazetteer;
      my $g = WWW::Gazetteer->new('calle');

    The find method looks up geographical information and returns it to you.
    It takes in a country and a city, with the recommended syntax being ISO
    3166 code and city name. However, it also tries to do what you mean.

    Note that there may be more than one town or city with that name in the
    country. You will get a list of hashrefs for each town/city.

      my @londons = $g->find("UK" => "London");
      my @londons = $g->find("United Kingdom" => "London");
      my @londons = $g->find("London", "United Kingdom");
