I like this solution the best from the perspective of simplicity and
fool-proof-ness.  I had considered it before but rejected it as leading
to duplication of the license.  Now I realize I can just "put a symbolic
link" in LICENSE.txt and move the actual text of the license to
__init__.py as you suggest.

This is fixed in CVS now.
