Python Software Foundation License
Python 2.1.1 license
This is the official license for the Python 2.1.1 release:
A. HISTORY OF THE SOFTWARE
==========================
Python was created in the early 1990s by Guido van Rossum at Stichting
Mathematisch Centrum (CWI) in the Netherlands as a successor of a language
called ABC. Guido is Python's principal author, although it includes many
contributions from others. The last version released from CWI was Python 1.2.
In 1995, Guido continued his work on Python at the Corporation for National
Research Initiatives (CNRI) in Reston, Virginia where he released several
versions of the software. Python 1.6 was the last of the versions released by
CNRI. In 2000, Guido and the Python core development team moved to BeOpen.com
to form the BeOpen PythonLabs team. Python 2.0 was the first and only release
from BeOpen.com.
Following the release of Python 1.6, and after Guido van Rossum left CNRI to
work with commercial software developers, it became clear that the ability to
use Python with software available under the GNU Public License (GPL) was very
desirable. CNRI and the Free Software Foundation (FSF) interacted to develop
enabling wording changes to the Python license. Python 1.6.1 is essentially the
same as Python 1.6, with a few minor bug fixes, and with a different license
that enables later versions to be GPL-compatible. Python 2.1 is a derivative
work of Python 1.6.1, as well as of Python 2.0.
After Python 2.0 was released by BeOpen.com, Guido van Rossum and the other
PythonLabs developers joined Digital Creations. All intellectual property added
from this point on, starting with Python 2.1 and its alpha and beta releases,
is owned by the Python Software Foundation (PSF), a non-profit modeled after
the Apache Software Foundation. See http://www.python.org/psf/ for more
information about the PSF.
Thanks to the many outside volunteers who have worked under Guido's direction
to make these releases possible.
