Hallo,

 

I've a question relating to http://creativecommons.org/licenses/by-sa/2.5/, which is used by the Tango Icon Library (http://tango.freedesktop.org/Tango_Desktop_Project):

 

If I got it right, it should be OK, if I change icons.

But would it be allowed to use these changed icons within a toolbar of a commercial software?

Would it be enough, if I place a license file in the same folder as the icon are?

Is it allowed, that the software uses a completely different license model and that only the changed icons are published with the same CC-license?

 

Thanks for your replies!

 

Regards,

Michael
