The conditions do not impose any non-free restrictions. By my reading, the grant and conditions are exactly equivalent to the well-understood Expat license grant and conditions. This work, provided its complete license grant and conditions was only the above text, would IMO be uncontroversially DFSG-free. Golda and Wikinaut: Now the question[1] about the sources remain. Could you clarify how the sources are related and how the development is being handled. This will help to decide proper packaging workflow for Debian.
