| 2 | ========================== |
| 3 | |
| 4 | Python was created in the early 1990s by Guido van Rossum at Stichting |
| 5 | Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands |
| 6 | as a successor of a language called ABC. Guido remains Python's |
| 7 | principal author, although it includes many contributions from others. |
| 8 | |
| 9 | In 1995, Guido continued his work on Python at the Corporation for |
| 10 | National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) |
| 11 | in Reston, Virginia where he released several versions of the |
| 12 | software. |
| 13 | |
| 14 | In May 2000, Guido and the Python core development team moved to |
| 15 | BeOpen.com to form the BeOpen PythonLabs team. In October of the same |
| 16 | year, the PythonLabs team moved to Digital Creations, which became |
| 17 | Zope Corporation. In 2001, the Python Software Foundation (PSF, see |
| 18 | https://www.python.org/psf/) was formed, a non-profit organization |
| 19 | created specifically to own Python-related Intellectual Property. |
| 20 | Zope Corporation was a sponsoring member of the PSF. |
| 21 | |
| 22 | All Python releases are Open Source (see http://www.opensource.org for |
| 23 | the Open Source Definition). Historically, most, but not all, Python |
| 24 | releases have also been GPL-compatible; the table below summarizes |
| 25 | the various releases. |
| 26 | |
| 27 | Release Derived Year Owner GPL- |
| 28 | from compatible? (1) |
| 29 | |
| 30 | 0.9.0 thru 1.2 1991-1995 CWI yes |
| 31 | 1.3 thru 1.5.2 1.2 1995-1999 CNRI yes |
| 32 | 1.6 1.5.2 2000 CNRI no |
| 33 | 2.0 1.6 2000 BeOpen.com no |
| 34 | 1.6.1 1.6 2001 CNRI yes (2) |
| 35 | 2.1 2.0+1.6.1 2001 PSF no |
| 36 | 2.0.1 2.0+1.6.1 2001 PSF yes |
| 37 | 2.1.1 2.1+2.0.1 2001 PSF yes |
| 38 | 2.1.2 2.1.1 2002 PSF yes |
| 39 | 2.1.3 2.1.2 2002 PSF yes |
| 40 | 2.2 and above 2.1.1 2001-now PSF yes |
| 41 | |
| 42 | Footnotes: |
| 43 | |
| 44 | (1) GPL-compatible doesn't mean that we're distributing Python under |
| 45 | the GPL. All Python licenses, unlike the GPL, let you distribute |
| 46 | a modified version without making your changes open source. The |
| 47 | GPL-compatible licenses make it possible to combine Python with |
| 48 | other software that is released under the GPL; the others don't. |
| 49 | |
| 50 | (2) According to Richard Stallman, 1.6.1 is not GPL-compatible, |
| 51 | because its license has a choice of law clause. According to |
| 52 | CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 |
| 53 | is "not incompatible" with the GPL. |
| 54 | |
| 55 | Thanks to the many outside volunteers who have worked under Guido's |
| 56 | direction to make these releases possible. |

| 409 | XZ Utils Licensing |
| 410 | ================== |
| 411 | |
| 412 | Different licenses apply to different files in this package. Here |
| 413 | is a rough summary of which licenses apply to which parts of this |
| 414 | package (but check the individual files to be sure!): |
| 415 | |
| 416 | - liblzma is in the public domain. |
| 417 | |
| 418 | - xz, xzdec, and lzmadec command line tools are in the public |
| 419 | domain unless GNU getopt_long had to be compiled and linked |
| 420 | in from the lib directory. The getopt_long code is under |
| 421 | GNU LGPLv2.1+. |
| 422 | |
| 423 | - The scripts to grep, diff, and view compressed files have been |
| 424 | adapted from gzip. These scripts and their documentation are |
| 425 | under GNU GPLv2+. |
| 426 | |
| 427 | - All the documentation in the doc directory and most of the |
| 428 | XZ Utils specific documentation files in other directories |
| 429 | are in the public domain. |
| 430 | |
| 431 | - Translated messages are in the public domain. |
| 432 | |
| 433 | - The build system contains public domain files, and files that |
| 434 | are under GNU GPLv2+ or GNU GPLv3+. None of these files end up |
| 435 | in the binaries being built. |
| 436 | |
| 437 | - Test files and test code in the tests directory, and debugging |
| 438 | utilities in the debug directory are in the public domain. |
| 439 | |
| 440 | - The extra directory may contain public domain files, and files |
| 441 | that are under various free software licenses. |
| 442 | |
| 443 | You can do whatever you want with the files that have been put into |
| 444 | the public domain. If you find public domain legally problematic, |
| 445 | take the previous sentence as a license grant. If you still find |
| 446 | the lack of copyright legally problematic, you have too many |
| 447 | lawyers. |
| 448 | |
| 449 | As usual, this software is provided "as is", without any warranty. |
| 450 | |
| 451 | If you copy significant amounts of public domain code from XZ Utils |
| 452 | into your project, acknowledging this somewhere in your software is |
| 453 | polite (especially if it is proprietary, non-free software), but |
| 454 | naturally it is not legally required. Here is an example of a good |
| 455 | notice to put into "about box" or into documentation: |
| 456 | |
| 457 | This software includes code from XZ Utils <https://tukaani.org/xz/>. |
| 458 | |
| 459 | The following license texts are included in the following files: |
| 460 | - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1 |
| 461 | - COPYING.GPLv2: GNU General Public License version 2 |
| 462 | - COPYING.GPLv3: GNU General Public License version 3 |
| 463 | |
| 464 | Note that the toolchain (compiler, linker etc.) may add some code |
| 465 | pieces that are copyrighted. Thus, it is possible that e.g. liblzma |
| 466 | binary wouldn't actually be in the public domain in its entirety |
| 467 | even though it contains no copyrighted code from the XZ Utils source |
| 468 | package. |
| 469 | |
| 470 | If you have questions, don't hesitate to ask the author(s) for more |
| 471 | information. |
