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 a modified
version without making your changes open source. The GPL-compatible licenses
make it possible to combine Python with other software that is released
under the GPL; the others don't. 

(2) According to Richard Stallman, 1.6.1 is not GPL-compatible, because its
license has a choice of law clause. According to CNRI, however, Stallman's
lawyer has told CNRI's lawyer that 1.6.1 is "not incompatible" with the GPL.

Thanks to the many outside volunteers who have worked under Guido's
direction to make these releases possible.
