# Third-party notices

Source: https://libtmux.org/en/lua/latest/third-party-notices/

> Licences and attribution for the tools that build libtmux.org and the software libtmux depends on.

libtmux and this site are built with open-source software. Several of those
licences ask that their notice text travel with the work, so it is reproduced
here.

### A note on Doxygen

Doxygen is licensed GPL-2.0-only. It runs as a build step that reads libtmux's
own headers and emits XML; that XML is rendered by Breathe and Sphinx, and no
Doxygen-generated HTML is published. Running a GPL program over your own input
does not place its licence on the output, and libtmux does not distribute
Doxygen or any modified version of it.

## Reference hosting

Three ports deep-link to the canonical host their ecosystem already uses,
rather than duplicating it here:

- Rust: [docs.rs](https://docs.rs/libtmux)
- Go: [pkg.go.dev](https://pkg.go.dev/github.com/libtmux/libtmux-go/tmux)
- Java and Kotlin: [javadoc.io](https://javadoc.io/doc/io.github.libtmux/libtmux)

Those sites are operated independently of this project and carry their own
terms.

## libtmux itself

Each port is MIT licensed. See the `LICENSE` file in that port's repository
for the authoritative text.
