Greg:

Exactly! And the tool [0] I used to detect the licenses can also
collect the exact matched text: so based on this we could craft a
script to do the grunt work of deleting the boilerplate and be
reasonably smart about it:

 - focus on GPL first, ignoring BSD/MIT for now
 - only take out unambiguous boilerplate that is matched exactly
 - and only take it out if there a proper and corresponding
   license identifier already there, or add one otherwise
