third-party components listed below, each of which remains the property of its
respective owner and is provided under its own license. The notices and license
texts in this file apply only to the corresponding third-party component and not
to MontaukOS as a whole.

This file is provided to satisfy the attribution and redistribution conditions of
those licenses. Where a component permits a choice of license, MontaukOS relies on
the option reproduced here.
