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:

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.
