-# A. HISTORY OF THE SOFTWARE
-# ==========================
-#
-# Python was created in the early 1990s by Guido van Rossum at Stichting
-# Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
-# as a successor of a language called ABC.  Guido remains Python's
-# principal author, although it includes many contributions from others.
-#
-# In 1995, Guido continued his work on Python at the Corporation for
-#     National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
-# in Reston, Virginia where he released several versions of the
-# software.
-#
-# In May 2000, Guido and the Python core development team moved to
-# BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
-# year, the PythonLabs team moved to Digital Creations (now Zope
-# Corporation, see http://www.zope.com).  In 2001, the Python Software
-# Foundation (PSF, see http://www.python.org/psf/) was formed, a
-# non-profit organization created specifically to own Python-related
-# Intellectual Property.  Zope Corporation is a sponsoring member of
-# the PSF.
-#
-# All Python releases are Open Source (see http://www.opensource.org for
-# the Open Source Definition).  Historically, most, but not all, Python
-# releases have also been GPL-compatible; the table below summarizes
-# the various releases.
-#

-# Footnotes:
-#
-# (1) GPL-compatible doesn't mean that we're distributing Python under
-# the GPL.  All Python licenses, unlike the GPL, let you distribute
-# a modified version without making your changes open source.  The
-# GPL-compatible licenses make it possible to combine Python with
-#     other software that is released under the GPL; the others don't.
-#
-# (2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
-# because its license has a choice of law clause.  According to
-# CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
-# is "not incompatible" with the GPL.
-#
-# Thanks to the many outside volunteers who have worked under Guido's
-# direction to make these releases possible.
