  This is false, in order to do this, you need to add an exemption
clause to the GPL.  You can do this for your own code, but you cannot
take someone elses' GPL'ed code (say, libmpeg2) and add an exemption
clause to it for them.  Each author must do it.

  Do you remember back before Qt was GPL'ed and you could not add KDE
front-ends to GPL'ed programs?  Same thing.

  Thanks for not reading any relevant FAQs or anything, it's really
helped this discussion move forward,
