# Included works
jsix includes and/or is derived from a number of other works, listed here.

## printf
The implementation of jsix's `*printf()` family of functions is derived from
Marco Paland and Eyal Rozenberg's tiny [printf][] library, which is also
released under the terms of the MIT license:

## Zstandard
The implementation of jsix's initrd contains zstd-compressed data. Zstd
decompression is handled by the reference [zstd][] library, which is released
under either a BSD or GPL license. I have chosen to use it under the BSD
license terms, shown below:
