## License

Racket is distributed under the MIT license and the Apache version 2.0 license, at your option. However, the Racket runtime system includes components distributed under other licenses. In short:

- The Racket CS Scheme runtime system embeds Chez Scheme, which is distributed under the Apache version 2.0 license.

- The Racket BC runtime system includes code distributed under the GNU Lesser General Public License, version 3.

Except for Windows executables that are created with the “embed DLLs” option, the runtime system remains separate as a shared library or additional executable, which means that it is dynamically linked and can be replaced with a modified variant by users.

See "LICENSE-LGPL.txt" in your Racket installation’s "share" directory for the full text of the GNU Lesser General Public License.

See "LICENSE-APACHE.txt" in your Racket installation’s "share" directory for the full text of the Apache version 2.0 license.

See "LICENSE-MIT.txt" in your Racket installation’s "share" directory for the full text of the MIT license.
