XZ Utils Licensing
|
|
==================
|
|
|
|
Different licenses apply to different files in this package. Here
|
|
is a rough summary of which licenses apply to which parts of this
|
|
package (but check the individual files to be sure!):
|
|
|
|
- liblzma is in the public domain.
|
|
|
|
- xz, xzdec, and lzmadec command line tools are in the public
|
|
domain unless GNU getopt_long had to be 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 gzip. These scripts and their documentation are
|
|
under GNU GPLv2+.
|
|
|
|
- All the documentation in the doc directory and most of the
|
|
XZ Utils specific documentation files in other directories
|
|
are in the public domain.
|
|
|
|
- Translated messages are in the public domain.
|
|
|
|
- The build system contains public domain files, and files that
|
|
are under GNU GPLv2+ or GNU GPLv3+. None of these files end up
|
|
in the binaries being built.
|
|
|
|
- Test files and test code in the tests directory, and debugging
|
|
utilities in the debug directory are in the public domain.
|
|
|
|
- The extra directory may contain public domain files, and files
|
|
that are under various free software licenses.
|
|
|
|
You can do whatever you want with the files that have been put into
|
|
the public domain. If you find public domain legally problematic,
|
|
take the previous sentence as a license grant. If you still find
|
|
the lack of copyright legally problematic, you have too many
|
|
lawyers.
|
|
|
|
As usual, this software is provided "as is", without any warranty.
|
|
|
|
If you copy significant amounts of public domain code from XZ Utils
|
|
into your project, acknowledging this somewhere in your software is
|
|
polite (especially if it is proprietary, non-free software), but
|
|
naturally it is not legally required. Here is an example of a good
|
|
notice to put into "about box" or into documentation:
|
|
|
|
This software includes code from XZ Utils <http://tukaani.org/xz/>.
|
|
|
|
The following license texts are included in the following files:
|
|
- 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
|
|
|
|
Note that the toolchain (compiler, linker etc.) may add some code
|
|
pieces that are copyrighted. Thus, it is possible that e.g. liblzma
|
|
binary wouldn't actually be in the public domain in its entirety
|
|
even though it contains no copyrighted code from the XZ Utils source
|
|
package.
|
|
|
|
If you have questions, don't hesitate to ask the author(s) for more
|
|
information. |
