Preamble

This license establishes the terms under which a given free software Package
may be copied, modified, distributed, and/or redistributed. The intent is that
the Copyright Holder maintains some artistic control over the development of
that Package while still keeping the Package available as open source and free
software.

You are always permitted to make arrangements wholly outside of this license
directly with the Copyright Holder of a given Package. If the terms of this
license do not permit the full use that you propose to make of the Package,
you should contact the Copyright Holder and seek a different licensing
arrangement.
