Well, suppose one file contains algorithms, ideas, or code fragments from
both GNU and BSD liscenced source. Since BSD liscence is less restrictive,
maybe put everying under GNU is OK? But BSD people won't be happy. If GNU
protects ONLY the exact coding. Maybe a rewrite of its algorithms and
ideas can get rid of GNU?  But again, it falls within the "derived" class.
