The Creative Commons licenses are modular licenses for immaterial works (but  
they are not really appropriate for software).  Wikipedia uses CC-BY-SA, for  
instance.  NC and ND are the two other modules that exist.  CC means  
"Creative Commons", BY means "Attribution" (compulsory in some legislations),  
SA means "ShareAlike" (like GPL's copyleft), NC mean "NonCommercial" and ND  
mean "NoDerivatives" (which cannot be used along with SA).
