The project is open-source, using the WOL (wide open license), so just use pieces of it anywhere you like. Only We'd appreciate that you email us any modifications, similar interesting projects, etc.
Sad to say, the extensive documentation is available in danish only, but feel free to download a copy (msWord-format).
Developers should also check out the JavaDoc documentation available here.
