1 Format-Specification: http://svn.debian.org/wsvn/dep/web/deps/dep5.mdwn?rev=135
2 Name: XZ Utils
3 Maintainer: Lasse Collin <lasse.collin@tukaani.org>
4 Source: http://tukaani.org/xz
5 http://git.tukaani.org/xz.git
6 X-Authors:
7 XZ Utils is developed and maintained upstream by Lasse Collin. Major
8 portions are based on code by other authors; see AUTHORS for details.
9 Most of the source has been put into the public domain, but some files
10 have not (details below).
11 X-Overview:
12 Different licenses apply to different files in this package. Here
13 is a rough summary of which licenses apply to which parts of this
14 package (but check the individual files to be sure!):
15 .
16 - liblzma is in the public domain.
17 .
18 - xz, xzdec, and lzmadec command line tools are in the public
19 domain unless GNU getopt_long had to be compiled and linked
20 in from the lib directory. The getopt_long code is under
21 GNU LGPLv2.1+.
22 .
23 - The scripts to grep, diff, and view compressed files have been
24 adapted from gzip. These scripts and their documentation are
25 under GNU GPLv2+.
26 .
27 - All the documentation in the doc directory and most of the
28 XZ Utils specific documentation files in other directories
29 are in the public domain.
30 .
31 - Translated messages are in the public domain.
32 .
33 - The build system contains public domain files, and files that
34 are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
35 in the binaries being built.
36 .
37 - Test files and test code in the tests directory, and debugging
38 utilities in the debug directory are in the public domain.
39 .
40 - The extra directory may contain public domain files, and files
41 that are under various free software licenses.
42 .
43 You can do whatever you want with the files that have been put into
44 the public domain. If you find public domain legally problematic,
45 take the previous sentence as a license grant. If you still find
46 the lack of copyright legally problematic, you have too many
47 lawyers.
48 .
49 As usual, this software is provided "as is", without any warranty.
50 .
51 If you copy significant amounts of public domain code from XZ Utils
52 into your project, acknowledging this somewhere in your software is
53 polite (especially if it is proprietary, non-free software), but
54 naturally it is not legally required. Here is an example of a good
55 notice to put into "about box" or into documentation:
56 .
57 This software includes code from XZ Utils <http://tukaani.org/xz/>.
58 .
59 The following license texts are included in the following files:
60 - COPYING.LGPLv2.1: GNU Lesser General Public License version 2.1
61 - COPYING.GPLv2: GNU General Public License version 2
62 - COPYING.GPLv3: GNU General Public License version 3
63 .
64 Note that the toolchain (compiler, linker etc.) may add some code
65 pieces that are copyrighted. Thus, it is possible that e.g. liblzma
66 binary wouldn't actually be in the public domain in its entirety
67 even though it contains no copyrighted code from the XZ Utils source
68 package.
69 .
70 If you have questions, don't hesitate to ask the author(s) for more
71 information.
72 X-Note:
73 The rest of this file only describes the source package. The binary
74 packages contain some files derived from other works: for example,
75 all images in the API documentation come from Doxygen.

100 COPYING says that most docs are in the public domain. Maybe that's not
101 clear enough, but on the other hand it looks a bit stupid to put
102 copyright information in tiny and relatively small docs like README.
103 .
104 I don't dare to say that _all_ XZ Utils specific docs are in the public
105 domain unless otherwise mentioned in the file. I'm including PDF files
106 generated by groff + ps2pdf, and some day I might include Doxygen-
107 generated HTML docs too. Those don't include any copyright notices, but
108 it seems likely that groff + ps2pdf or at least Doxygen put some
109 copyrighted content into the generated files.

262 changelog.gz (commit 975d8fd) explains:
263 .
264 Recreated the BCJ test files for x86 and SPARC. The old files
265 were linked with crt*.o, which are copyrighted, and thus the
266 old test files were not in the public domain as a whole. They
267 are freely distributable though, but it is better to be careful
268 and avoid including any copyrighted pieces in the test files.
269 The new files are just compiled and assembled object files,
270 and thus don't contain any copyrighted code.
