We track licenses for third-party materials in two ways:

* We use [REUSE](https://reuse.software) to track license information for
  in-tree source files - both those authored by the Rust project and those
  authored by third parties. See `REUSE.toml`, and our cached output of the
  `reuse` tool which is committed to `license-metadata.json`.
* We use `cargo` to track license information for out-of-tree dependencies.

These two sources of information are collected by the tool `generate-copyright`
into a file called `COPYRIGHT.html`, which is shipped with each binary release
of Rust. Please refer to that file for detailed information as to the components of
any given Rust release. We also produce a `COPYRIGHT-library.html` file which only
covers the subset of source code used in the Rust Standard Library, as opposed
to the toolchain as a whole.
