Python3
A. HISTORY OF THE SOFTWARE
==========================
Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands as a
successor of a language called ABC. Guido remains Python's principal author,
although it includes many contributions from others.
In 1995, Guido continued his work on Python at the Corporation for National Research
Initiatives (CNRI, see http://www.cnri.reston.va.us) in Reston, Virginia where he
released several versions of the software.
In May 2000, Guido and the Python core development team moved to BeOpen.com
to form the BeOpen PythonLabs team. In October of the same year, the PythonLabs
team moved to Digital Creations (now Zope Corporation, see http://www.zope.com).
In 2001, the Python Software Foundation (PSF, see http://www.python.org/psf/) was
formed, a non-profit organization created specifically to own Python-related Intellectual
Property. Zope Corporation is a sponsoring member of the PSF.
All Python releases are Open Source (see http://www.opensource.org for the Open
Source Definition). Historically, most, but not all, Python releases have also been
GPL-compatible; the table below summarizes the various releases.

Footnotes:
(1) GPL-compatible doesn't mean that we're distributing Python under
the GPL. All Python licenses, unlike the GPL, let you distribute
