Upstream-Name: XZ Utils
Upstream-Contact:
Lasse Collin <lasse.collin@tukaani.org>
https://tukaani.org/xz/lists.html
Source:
https://tukaani.org/xz
https://github.com/tukaani-project/xz
Comment:
XZ Utils is developed and maintained upstream by Lasse Collin. Major
portions are based on code by other authors; see AUTHORS for details.
Most of the source has been put into the public domain, but some files
have not (details below).
.
This file describes the source package. The binary packages contain
some files derived from other works: for example, images in the API
documentation come from Doxygen.
License:
Different licenses apply to different files in this package. Here
is a summary of which licenses apply to which parts of this package:
.
- liblzma is under the BSD Zero Clause License (0BSD).
.
- The command line tools xz, xzdec, lzmadec, and lzmainfo are
under 0BSD except that, on systems that don't have a usable
getopt_long, GNU getopt_long is compiled and linked in from the
'lib' directory. The getopt_long code is under GNU LGPLv2.1+.
.
- The scripts to grep, diff, and view compressed files have been
adapted from GNU gzip. These scripts (xzgrep, xzdiff, xzless,
and xzmore) are under GNU GPLv2+. The man pages of the scripts
are under 0BSD; they aren't based on the man pages of GNU gzip.
.
- Most of the XZ Utils specific documentation that is in
plain text files (like README, INSTALL, PACKAGERS, NEWS,
and ChangeLog) are under 0BSD unless stated otherwise in
the file itself. The files xz-file-format.txt and
lzma-file-format.xt are in the public domain but may
be distributed under the terms of 0BSD too.
.
- Translated messages and man pages are under 0BSD except that
some old translations are in the public domain.
.
- Test files and test code in the 'tests' directory, and
debugging utilities in the 'debug' directory are under
the BSD Zero Clause License (0BSD).
.
- The GNU Autotools based build system contains files that are
under GNU GPLv2+, GNU GPLv3+, and a few permissive licenses.
These files don't affect the licensing of the binaries being
built.
.
- The 'extra' directory contains files that are under various
free software licenses. These aren't built or installed as
part of XZ Utils.
.
For the files under the BSD Zero Clause License (0BSD), if
a copyright notice is needed, the following is sufficient:
.
Copyright (C) The XZ Utils authors and contributors
.
If you copy significant amounts of 0BSD-licensed code from XZ Utils
into your project, acknowledging this somewhere in your software is
polite (especially if it is proprietary, non-free software), but
it is not legally required by the license terms. Here is an example
of a good notice to put into "about box" or into documentation:
.
This software includes code from XZ Utils <https://tukaani.org/xz/>.
.
The following license texts are included in the following files:
- COPYING.0BSD: BSD Zero Clause License
- COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
- COPYING.GPLv2: GNU General Public License version 2
- COPYING.GPLv3: GNU General Public License version 3
.
A note about old XZ Utils releases:
.
XZ Utils releases 5.4.6 and older and 5.5.1alpha have a
significant amount of code put into the public domain and
that obviously remains so. The switch from public domain to
0BSD for newer releases was made in Febrary 2024 because
public domain has (real or perceived) legal ambiguities in
some jurisdictions.
.
There is very little *practical* difference between public
domain and 0BSD. The main difference likely is that one
shouldn't claim that 0BSD-licensed code is in the public
domain; 0BSD-licensed code is copyrighted but available under
an extremely permissive license. Neither 0BSD nor public domain
require retaining or reproducing author, copyright holder, or
license notices when distributing the software. (Compare to,
for example, BSD 2-Clause "Simplified" License which does have
such requirements.)
.
If you have questions, don't hesitate to ask for more information.
The contact information is in the README file.
