Ok, let me rephrase. The Python license requires the copyright notice:

"Copyright (c) 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008 Python
Software Foundation; All Rights Reserved"

to appear in some way with every distribution of Python, either source
or executable. No problem with that.

But since I'm using Stackless, is there some other copyright notice that
I should put in addition to that one?

On other words: could it be that the Stackless developers don't want to
be credited for their work? *That* would sound strange to me.

I have no problems at all with the Python license. I just want to give
proper credit to the developers of the software I distribute under that
license (both because they deserve it and because the license requires
me to do it).

Totally agree (I'm Italian).
