  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.
