[Fedora-desktop-list] What is the license on the Fedora artwork?

[Steven Garrity <stevelist@xxxxxxxxxxxxxxxx>]

Simple question - apologies if it has already been covered: What, if 
any, license applies to the Fedora artwork (both the final product in 
the CVS and the vector originals that Garrett has kindly shared)?

I'm asking with a specific using in mind (adapting the bluecurve 
throbber to a Mozilla Thunderbird theme), but I'm also curious in general.

Thanks,
Steven Garrity
