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.
