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 . src/scripts/xzgrep.in --------------------- xzgrep -- a wrapper around a grep program that decompresses files as needed Adapted from a version sent by Charles Levert Copyright (C) 1998, 2001, 2002, 2006, 2007 Free Software Foundation Copyright (C) 1993 Jean-loup Gailly Modified for XZ Utils by Andrew Dudman and Lasse Collin.
