+all source code in the directories `lib/sqfs`, `lib/util` and `include/sqfs`
+with the following exceptions:
+
+ - `lib/util/xxhash.c` contains a modified implementation of the xxhash32
+   algorithm. See `licenses/xxhash.txt` for copyright and licensing
+   information (2 clause BSD license).
+ - `lib/lz4` contains files extracted from the LZ4 compression library.
+   See `lib/lz4/README` for details and `licenses/LZ4.txt` for copyright and
+   licensing information (2 clause BSD license).
+ - `lib/zlib` contains files that have been extracted from the the zlib
+   compression library and modified. See `lib/zlib/README` for details
+   and `licenses/zlib.txt` for details.
+ - `lib/util/hash_table.c`, `include/hash_table.h` and
+   `lib/util/fast_urem_by_const.h` contain a hash table implementation (MIT
+   license). See `licenses/hash_table.txt` for details.
+
+The rest of squashfs-tools-ng is released under the terms and conditions of
+the **GNU General Public License version 3 or later**, with the following
+exceptions:
+
+ - `lib/compat/fnmatch.c` has been copied from Musl libc.

+ - `lib/compat/getopt_long.c` has been copied from Musl libc.
+ - `lib/compat/getsubopt.c` has been copied from Musl libc.
+
+The components copied from Musl libc are subejct to an MIT style license.
+See `liceneses/musl.txt` for details and only compiled into executable programs
+if the target system does not provide an implementation.
+
+Copies of the LGPLv3 and GPLv3 are included in `licenses/LGPLv3.txt` and

+
+The original source code of squashfs-tools-ng has been written by David
+Oberhollenzer in 2019 and onward. Additional contributions have been added
+since the initial release which makes some parts of the package subject to the
+copyright of the respective authors. Appropriate copyright notices and SPDX
+identifiers are included in the source code files.
+
+Although the existing squashfs-tools and the Linux kernel implementation have
+been used for testing, the source code in this package is neither based on,
+nor derived from either of them.
+
+## Documentation, examples and the Build System
+
+The auto-tools based build system has in large parts been hacked together by
+copy & pasting from various tutorials and other projects (mostly util-linux,
+and mtd-utils), overhauled many times since 2015.
+
+The m4 macros in the `m4` directory were copied verbatim and have explicit
+licenses. Please respect those. As for everything else, feel free to copy and
+paste it as you wish.
+
+The `doc` directory contains measurement data, pseudo lab reports and an RFC
+style write-up of the SquashFS format. You may do with those as you please.
+
+If you use those as a basis for writing about SquashFS or this package, please
+cite your sources and mark verbatim quotations as such. I won't be angry if you
+don't, but a thesis supervisor, reviewer or fellow Wikipedian might be.
+
+The example programs in the `extras` directory are licensed under
+the **0BSD license**, a copy of which can be found in `licenses/0BSD.txt`.
