GNU GENERAL PUBLIC LICENSE
Version 3, 29 June 2007

Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.

                            Preamble

The GNU General Public License is a free, copyleft license for software
and other kinds of works, designed 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 it for many of our
software packages.

When we talk about free software, we are referring to freedom, not price.
Our General Public Licenses are designed to make sure that you have the
freedom to distribute copies of free software (and charge for this service if
you wish), that you receive source code or can get it if you want it, that
you can change the software or use pieces of it in new free programs, and
that you are notified of your rights when you receive a copy of a program.

To protect your rights, we need to make restrictions that forbid anyone to
deny you these rights or to ask you to surrender the rights. These
restrictions translate to certain responsibilities for you if you distribute
copies of the software, or if you modify it.

For example, if you distribute copies of a program, whether modified or
unmodified, you must pass on to the recipients the same freedoms that you
received. You must make sure that everyone else also receives or can get
the source code. And you must show them these terms so they know their
rights.

Developers that use the GPL protect your freedom by requiring all
modifications and extended versions of the program to be free as well. When
you distribute this software, you must pass on the same license terms to the
recipients. Therefore, any program that is derived from or includes GPL
licensed code is also GPL licensed. This ensures that every user of the
software also receives the source code and the freedom to modify it.

There are many free software licenses out there, but the GPL is the most
widely used. It is used by the GNU Project and by many other projects
around the world. The GPL is a strong copyleft license, which means that
any derivative work you create will also be subject to the GPL, ensuring
that it remains free software.

The GPL is designed to be simple and easy to understand, so that everyone
can use it. It is also designed to be flexible, so that it can be used for
a wide range of software, from small utilities to large operating systems.

We hope that you will join the millions of users and developers who have
already embraced the spirit of freedom and cooperation that the GPL embodies.
By using, modifying, and distributing GPL licensed software, you are helping
to promote the ideals of free software and to ensure that it remains a vital
and growing part of the computing landscape.

Thank you for your interest in free software and the GNU General Public
License.

You must distribute the Source Code of the Program or your Modified Version
under the terms of this License. The Source Code must be accompanied by a
copy of this License.

Source Code or make it available.

6. Modified Versions.

You may not modify this License or impose any further restrictions on the
exercise of the rights granted under this License.

7. Termination.

This License and the rights granted hereunder will terminate automatically
