 Everyone is permitted to copy and distribute verbatim copies

                            Preamble

  The GNU General Public License is a free, copyleft license for
software and other kinds of works.

  The licenses for most software and other practical works are designed
to take away your freedom to share and change the works.  By contrast,
the GNU General Public License is intended to guarantee your freedom to
share and change all versions of a program--to make sure it remains free
software for all its users.  We, the Free Software Foundation, use the
GNU General Public License for most of our software; it applies also to
any other work released this way by its authors.  You can apply it to
your programs, too.

  This License is a copyleft license, which means that derivative works
must be released under the same or an equivalent license. The full text
of the GNU General Public License, version 3, governs your rights to
copy, distribute, and modify covered software, including the right to
receive source code, the prohibition on additional restrictions, and the
disclaimer of warranty and limitation of liability set out in Sections 15
and 16 of the full license.

  The complete, authoritative text of the GNU General Public License
version 3 is published by the Free Software Foundation and is available
at:

This repository's source code is licensed under the terms of that
license, "GPL-3.0-or-later", meaning you may use it under the terms of
version 3 of the GNU General Public License, or (at your option) any
later version published by the Free Software Foundation.

A local verbatim copy of the full GPLv3 license text should accompany
every distribution of this software; if it is missing, obtain it from
the URL above before redistributing.
