=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.
