=head1 NAME

Game::TextMapper::Mapper::Hex - a mapper for hex maps

=head1 DESCRIPTION

This class knows how to parse a text containing a square map description into
SVG definitions, and regions. Once the map is built, this class knows how to
generate the SVG for the entire map.

=head1 SEE ALSO

This class is derived from L<Game::TextMapper::Mapper>.

It uses L<Game::TextMapper::Point::Square> to represent points (regions) and
L<Game::TextMapper::Line::Square> to represent lines.

L<Game::TextMapper::Mapper::Hex> is a similar class for hex maps.
