10 XZ Utils is developed and maintained upstream by Lasse Collin. Major
11 portions are based on code by other authors; see AUTHORS for details.
12 Most of the source has been put into the public domain, but some files
13 have not (details below).
15 This file describes the source package. The binary packages contain
16 some files derived from other works: for example, images in the API
17 documentation come from Doxygen.
19 Different licenses apply to different files in this package. Here
20 is a rough summary of which licenses apply to which parts of this
21 package (but check the individual files to be sure!):
23 - liblzma is in the public domain.
25 - xz, xzdec, and lzmadec command line tools are in the public
26 domain unless GNU getopt_long had to be compiled and linked
27 in from the lib directory. The getopt_long code is under
30 - The scripts to grep, diff, and view compressed files have been
31 adapted from gzip. These scripts and their documentation are
34 - All the documentation in the doc directory and most of the
35 XZ Utils specific documentation files in other directories
36 are in the public domain.
38 - Translated messages are in the public domain.
40 - The build system contains public domain files, and files that
41 are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
42 in the binaries being built.
44 - Test files and test code in the tests directory, and debugging
45 utilities in the debug directory are in the public domain.
47 - The extra directory may contain public domain files, and files
48 that are under various free software licenses.
50 You can do whatever you want with the files that have been put into
51 the public domain. If you find public domain legally problematic,
52 take the previous sentence as a license grant. If you still find
53 the lack of copyright legally problematic, you have too many
56 As usual, this software is provided "as is", without any warranty.
58 If you copy significant amounts of public domain code from XZ Utils
59 into your project, acknowledging this somewhere in your software is
60 polite (especially if it is proprietary, non-free software), but
61 naturally it is not legally required. Here is an example of a good
62 notice to put into "about box" or into documentation:
64 This software includes code from XZ Utils <http://tukaani.org/xz/>.
66 The following license texts are included in the following files:
67 - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
68 - COPYING.GPLv2: GNU General Public License version 2
69 - COPYING.GPLv3: GNU General Public License version 3
71 Note that the toolchain (compiler, linker etc.) may add some code
72 pieces that are copyrighted. Thus, it is possible that e.g. liblzma
73 binary wouldn't actually be in the public domain in its entirety
74 even though it contains no copyrighted code from the XZ Utils source
77 If you have questions, don't hesitate to ask the author(s) for more

104 COPYING says that most docs are in the public domain. Maybe that's not
105 clear enough, but on the other hand it looks a bit stupid to put
106 copyright information in tiny and relatively small docs like README.
108 I don't dare to say that _all_ XZ Utils specific docs are in the public
109 domain unless otherwise mentioned in the file. I'm including PDF files
110 generated by groff + ps2pdf, and some day I might include Doxygen-
111 generated HTML docs too. Those don't include any copyright notices, but
112 it seems likely that groff + ps2pdf or at least Doxygen put some
113 copyrighted content into the generated files.

194 changelog.gz (commit 975d8fd) explains:
196 Recreated the BCJ test files for x86 and SPARC. The old files
197 were linked with crt*.o, which are copyrighted, and thus the
198 old test files were not in the public domain as a whole. They
199 are freely distributable though, but it is better to be careful
200 and avoid including any copyrighted pieces in the test files.
201 The new files are just compiled and assembled object files,
202 and thus don't contain any copyrighted code.
