================================ The PyInstaller licensing terms ================================ Copyright (c) 2010-2022, PyInstaller Development Team Copyright (c) 2005-2009, Giovanni Bajo Based on previous work under copyright (c) 2002 McMillan Enterprises, Inc. PyInstaller is licensed under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version. Bootloader Exception -------------------- In addition to the permissions in the GNU General Public License, the authors give you unlimited permission to link or embed compiled bootloader and related files into combinations with other programs, and to distribute those combinations without any restriction coming from the use of those files. (The General Public License restrictions do apply in other respects; for example, they cover modification of the files, and distribution when not linked into a combined executable.) Bootloader and Related Files ---------------------------- Bootloader and related files are files which are embedded within the final executable. This includes files in directories: ./bootloader/ ./PyInstaller/loader Run-time Hooks ---------------------------- Run-time Hooks are a different kind of files embedded within the final executable. To ease moving them into a separate repository, or into the respective project, these files are now licensed under the Apache License, Version 2.0. Run-time Hooks are in the directory ./PyInstaller/hooks/rthooks About the PyInstaller Development Team -------------------------------------- The PyInstaller Development Team is the set of contributors to the PyInstaller project. A full list with details is kept in the documentation directory, in the file ``doc/CREDITS.rst``. The core team that coordinates development on GitHub can be found here: https://github.com/pyinstaller/pyinstaller. As of 2021, it consists of: * Hartmut Goebel * Jasper Harrison * Bryan Jones * Brenainn Woodsend * Rok Mandeljc Our Copyright Policy -------------------- PyInstaller uses a shared copyright model. Each contributor maintains copyright over their contributions to PyInstaller. But, it is important to note that these contributions are typically only changes to the repositories. Thus, the PyInstaller source code, in its entirety is not the copyright of any single person or institution. Instead, it is the collective copyright of the entire PyInstaller Development Team. If individual contributors want to maintain a record of what changes/contributions they have specific copyright on, they should indicate their copyright in the commit message of the change, when they commit the change to the PyInstaller repository. With this in mind, the following banner should be used in any source code file to indicate the copyright and license terms: #----------------------------------------------------------------------------- # Copyright (c) 2005-2022, PyInstaller Development Team. # # Distributed under the terms of the GNU General Public License (version 2 # or later) with exception for distributing the bootloader. # # The full license is in the file COPYING.txt, distributed with this software. # # SPDX-License-Identifier: (GPL-2.0-or-later WITH Bootloader-exception) #----------------------------------------------------------------------------- For run-time hooks, the following banner should be used: #----------------------------------------------------------------------------- # Copyright (c) 2005-2022, PyInstaller Development Team. # # Licensed under the Apache License, Version 2.0 (the "License"); # you may not use this file except in compliance with the License. # # The full license is in the file COPYING.txt, distributed with this software. # # SPDX-License-Identifier: Apache-2.0 #----------------------------------------------------------------------------- ================================ GNU General Public License ================================ https://gnu.org/licenses/gpl-2.0.html GNU GENERAL PUBLIC LICENSE Version 2, June 1991 Copyright (C) 1989, 1991 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. Preamble The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Library General Public License instead.) You can apply it to your programs, too. When we speak of 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 know you can do these things. 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 such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights. We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software. Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations. Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all. The precise terms and conditions for copying, distribution and modification follow. GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION 0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you". Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on wha
