That would seem to apply primarily because this is a derivative product 
of a Python distribution. Therefore, your description could be limited 
to "removed the rest of the distribution" followed by specific details 
of your changes making Queue into tube.

I believe so.

Since the PSF copyrighted the original work from which you are deriving, 
you have already agreed to do this in any distributed derived work:

   http://www.python.org/2.3/license.html

clearly says """provided, however, that PSF's License Agreement and 
PSF's notice of copyright, i.e., "Copyright (c) 2001, 2002, 2003 Python 
Software Foundation; All Rights Reserved" are retained in Python 2.3 
alone or in any derivative version prepared by Licensee."""

Should we wait until you publish tube and then remove *your* attribution 
to claim the code as our own?
