As is being reported everywhere, Creative Commons has officially launched their licensing tools:
Creative Commons, a nonprofit dedicated to promoting the creative reuse of intellectual works, launched its first product today: its machine-readable copyright licenses, available free of charge from creativecommons.org. The licenses allow copyright holders to easily inform others that their works are free for copying and other uses under specific conditions. These self-help tools offer new ways to distribute creative works on generous terms – from copyright to the public domain – and are available free of charge.
