+ License version 3, but not version 2.

+ - The GNU General Public License version 2, found in

+The contributed BDF and PCF drivers come with a license similar to
+that of the X Window System. It is compatible to the above two
+licenses (see files `src/bdf/README` and `src/pcf/README`). The same
+holds for the source code files `src/base/fthash.c` and
+`include/freetype/internal/fthash.h`; they were part of the BDF driver
+in earlier FreeType versions.
+
+The gzip module uses the zlib license (see `src/gzip/zlib.h`) which
+too is compatible to the above two licenses.
+
+The files `src/autofit/ft-hb.c` and `src/autofit/ft-hb.h` contain code
+taken almost verbatim from the HarfBuzz file `hb-ft.cc`, which uses
+the 'Old MIT' license, compatible to the above two licenses.
+
+The MD5 checksum support (only used for debugging in development
+builds) is in the public domain.

+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 .
+
+ 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.
