a “patent license” is any express agreement or commitment, however denominated, not to enforce a patent (such as an express permission to
practice a patent or covenant not to sue for patent infringement). To “grant” such a patent license to a party means to make such an agreement or
commitment not to enforce a patent against the party. If you convey a covered work, knowingly relying on a patent license, and the Corresponding
Source of the work is not available for anyone to copy, free of charge and under the terms of this License, through a publicly available network server
or other readily accessible means, then you must either (1) cause the Corresponding Source to be so available, or (2) arrange to deprive yourself of
the benefit of the patent license for this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the
patent license to downstream recipients. “Knowingly relying” means you have actual knowledge that, but for the patent license, your conveying the
covered work in a country, or your recipient’s use of the covered work in a country, would infringe one or more identifiable patents in that country that
you have reason to believe are valid. If, pursuant to or in connection with a single transaction or arrangement, you convey, or propagate by procuring
conveyance of, a covered work, and grant a patent license to some of the parties receiving the covered work authorizing them to use, propagate,
modify or convey a specific copy of the covered work, then the patent license you grant is automatically extended to all recipients of the covered work
and works based on it.
A patent license is “discriminatory” if it does not include within the scope of its coverage, prohibits the exercise of, or is conditioned on the non-
exercise of one or more of the rights that are specifically granted under this License. You may not convey a covered work if you are a party to an
arrangement with a third party that is in the business of distributing software, under which you make payment to the third party based on the extent
of your activity of conveying the work, and under which the third party grants, to any of the parties who would receive the covered work from you, a
discriminatory patent license (a) in connection with copies of the covered work conveyed by you (or copies made from those copies), or (b) primarily
for and in connection with specific products or compilations that contain the covered work, unless you entered into that arrangement, or that patent
license was granted, prior to 28 March 2007.
Nothing in this License shall be construed as excluding or limiting any implied license or other defenses to infringement that may otherwise be
available to you under applicable patent law.
12. No Surrender of Others’ Freedom.
If conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse
you from the conditions of this License. If you cannot convey a covered work so as to satisfy simultaneously your obligations under this License and
any other pertinent obligations, then as a consequence you may not convey it at all. For example, if you agree to terms that obligate you to collect a
royalty for further conveying from those to whom you convey the Program, the only way you could satisfy both those terms and this License would be
to refrain entirely from conveying the Program.
13. Use with the GNU Affero General Public License.
Notwithstanding any other provision of this License, you have permission to link or combine any covered work with a work licensed under version 3
of the GNU Affero General Public License into a single combined work, and to convey the resulting work. The terms of this License will continue to
apply to the part which is the covered work, but the special requirements of the GNU Affero General Public License, section 13, concerning interaction
through a network will apply to the combination as such.
14. Revised Versions of this License.
The Free Software Foundation may publish revised and/or new versions of the GNU General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version
number. If the Program specifies that a certain numbered version of the GNU General Public License “or any later version” applies to it, you have the
option of following the terms and conditions either of that numbered version or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of the GNU General Public License, you may choose any version ever published by the Free Software
Foundation. If the Program specifies that a proxy can decide which future versions of the GNU General Public License can be used, that proxy’s
public statement of acceptance of a version permanently authorizes you to choose that version for the Program. Later license versions may give you
additional or different permissions. However, no additional obligations are imposed on any author or copyright holder as a result of your choosing to
follow a later version.
15. Disclaimer of Warranty.
THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED
IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND,
EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS
FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD
THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. Limitation of Liability.
IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER
PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM
(INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS
BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
17. Interpretation of Sections 15 and 16.
If the disclaimer of warranty and limitation of liability provided above cannot be given local legal effect according to their terms, reviewing courts shall
apply local law that most closely approximates an absolute waiver of all civil liability in connection with the Program, unless a warranty or assumption
of liability accompanies a copy of the Program in return for a fee.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software
which everyone can redistribute and change under these terms. To do so, attach the following notices to the program. It is safest to attach them to the start
of each source file to most effectively state the exclusion of warranty; and each file should have at least the “copyright” line and a pointer to where the full
notice is found.
<one line to give the program’s name and a brief idea of what it does.> Copyright (C) <year> <name of author>
This program is free software: you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the
Free Software Foundation, either version 3 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of
