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:

@itemize[

 @item{The traditional Racket runtime system includes code distributed
       under the GNU Lesser General Public License, version 3.}

 @item{The Racket on Chez Scheme runtime system embeds Chez Scheme, which
       is distributed under the Apache version 2.0 license.}

]

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 @filepath{LICENSE-LGPL.txt} in your Racket installation's
@filepath{share} directory for the full text of the GNU Lesser General
Public License.

See @filepath{LICENSE-APACHE.txt} in your Racket installation's
@filepath{share} directory for the full text of the Apache version 2.0
license.

See @filepath{LICENSE-MIT.txt} in your Racket installation's
@filepath{share} directory for the full text of the MIT license.
