Oh, okay.  In that case, the important point is to carry the original
license along, but make it clear that it is not controlling for this
version of the code.  Personally, I would do something like this.
Just after the original copyright, insert:

	The following text appears here by the requirements of
	the licensor of an earlier version of this code.  It does
	NOT constitute the license for this version.  To see the
	license for this version, consult the file COPYING enclosed
	with your distribution, or etc. etc. etc.

The current Python license
( looks like this:
the operative license comes first (after a lengthy preamble explaining
what's going on) and then all the other dead licenses trail along behind.

To say that Bilbo's breath was taken away is no description at all.  There
are no words left to express his staggerment, since Men changed the language
that they learned of elves in the days when all the world was wonderful.
