[arch-dev-public] Licenses: Is Creative Commons in our list?

Excuse the naive question, but while putting together some PKGBUILDs for the Arch artwork stuff, I couldn't find any reference to the Creative Commons licenses in /usr/share/licenses. Am I missing something or do we need to add this to our collection? The Arch Linux logo (and other related artwork) is released under CC license so I want to make sure I flag these properly. Cheers, Thayer
