=head1 NAME

GIS::Distance::Fast - C implementation of GIS::Distance formulas.

=head1 DESCRIPTION

This distribution re-implements some, but not all, of the formulas
that come with L<GIS::Distance> in the C programming language.  C code
is generally much faster than the Perl equivalent.

See L<GIS::Distance/SPEED> for some benchmarking and how to run your
own benchmarks.

This module need not be used directly.  L<GIS::Distance> will automatically
use the C<GIS::Distance::Fast::*> formulas when installed.
