#1 Publi Domain is not a valid license

[Jari Aalto]

The Code is marked release as "Public Domain".

Unfortunately that is:
- Not a license
- The term is not legally recognized all over the world

See http://pinboard.in/u:jariaalto/t:license/t:top10 for more information, especially link "License - Public Domain - Why the Public Domain Isn't a License (Open Source Attorney Lawrence Rosen)"

Please consider licensing the code under proper OSI approved license. A good and safe choice would be the GPL.
