The distance computation between a line and a circle is based on David Eberly's
implementation, Copyright (c) 1998-2022 David Eberly, Geometric Tools,
Redmond WA 98052, distributed under the Boost Software License, Version 1.0.

The original GJK algorithm is a translation to Python of the translation to C of
the original Fortran implementation. The C implementation is from Diego Ruspini.
It is available from http://realtimecollisiondetection.net/files/gilbert.c

Some features related to the GJK algorithm have been inspired by
[Bullet](https://github.com/bulletphysics/bullet3/) (zlib license) and are
marked as such in the source code.

The EPA algorithm is adapted from
[Kevin Moran's GJK implementation](https://github.com/kevinmoran/GJK)
(MIT License or Unlicense).

A GJK intersection test and the MPR algorithm are based on libccd (for details,
see https://github.com/danfis/libccd). For the original code the copyright is
of Daniel Fiser <danfis@danfis.cz>. It has been released under 3-clause BSD
license.

The main GJK implementation is based on Jolt Physics, Copyright 2021 Jorrit
Rouwe, MIT license.

The translation to Python has been done by Alexander Fabisch and the glue
code around it is licensed under the 3-clause BSD license:
