=head1 SYNOPSIS

    use Alien::geos::af;

    use Env qw(@PATH);
    unshift @PATH, Alien::geos::af->bin_dir;

    print Alien::geos::af->dist_dir;

    
=head1 DESCRIPTION

GEOS is the Geometry Engine, Open Source.  See L<http://geos.osgeo.org/>.

The name Aien::geos::AF is chosen to not clash with a pre-existing
Alien::GEOS distribution.  This package differs in that it uses the
alienfile approach, hence the ::af suffix in the name.
