Upstream Source
===============
In General
----------
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+.
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.
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/>.
