+\section{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 2.0.1 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, including Python
+2.0.1 and its alpha and beta releases, is owned by the Python Software
+Foundation (PSF), a non-profit modeled after the Apache Software
+Foundation.  See \url{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.
