It is not the purpose of this secon to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this secon
has the sole purpose of protecng the integrity of the free soware distribuon system, which is implemented by public license pracces. Many people have
made generous contribuons to the wide range of soware distributed through that system in reliance on consistent applicaon of that system; it is up to the
author/donor to decide if he or she is willing to distribute soware through any other system and a licensee cannot impose that choice.
This secon is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribuon and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder
who places the Program under this License may add an explicit geographical distribuon limitaon excluding those countries, so that distribuon is permied
only in or among countries not thus excluded. In such case, this License incorporates the limitaon as if wrien in the body of this License.
9. The Free Soware Foundaon may publish revised and/or new versions of the General Public License from me to me. Such new versions will be similar
in spirit to the present version, but may dier in detail to address new problems or concerns.
Each version is given a disnguishing version number. If the Program species a version number of this License which applies to it and “any later version”, you
have the opon of following the terms and condions either of that version or of any later version published by the Free Soware Foundaon. If the Program
does not specify a version number of this License, you may choose any version ever published by the Free Soware Foundaon.
10. If you wish to incorporate parts of the Program into other free programs whose distribuon condions are dierent, write to the author to ask for
permission. For soware which is copyrighted by the Free Soware Foundaon, write to the Free Soware Foundaon; we somemes make excepons for
this. Our decision will be guided by the two goals of preserving the free status of all derivaves of our free soware and of promong the sharing and reuse of
soware generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, 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.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY
MODIFY AND/OR REDISTRIBUTE 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.

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 soware which
everyone can redistribute and change under these terms.
To do so, aach the following noces to the program. It is safest to aach them to the start of each source le to most eecvely convey the exclusion of
warranty; and each le should have at least the “copyright” line and a pointer to where the full noce is found.
one line to give the program’s name and an idea of what it does.

If the program is interacve, make it output a short noce like this when it starts in an interacve mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details
type `show w’. This is free soware, and you are welcome
to redistribute it under certain condions; type `show c’

The hypothecal commands `show w’ and `show c’ should show the appropriate parts of the General Public License. Of course, the commands you use may
be called something other than `show w’ and `show c’; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a “copyright disclaimer” for the program, if necessary. Here is a
sample; alter the names:
