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 (www.pythonlabs.com).  Python 2.0 is the first
release from PythonLabs.  Thanks to the many outside volunteers who
have worked under Guido's direction to make this release possible.

After Python 2.0 was released by BeOpen.com, Guido van Rossum and the
other PythonLabs developers joined Digital Creations.  The intention
is for all intellectual property added from this point on to be owned
by the Python Software Foundation (PSF), a non-profit that will be
created modeled after the Apache Software Foundation.  We will also
attempt to get the ownership in previous versions transferred to the
PSF, and straighten out the license to remove the GPL-incompatibility
introduced by CNRI's Python 1.6 license.  In the interim, Guido van
Rossum will own all new intellectual property, and no new license is
added.
