    139   A. HISTORY OF THE SOFTWARE
    140   ==========================
    141 
    142   Python was created in the early 1990s by Guido van Rossum at Stichting
    143   Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
    144   as a successor of a language called ABC.  Guido remains Python's
    145   principal author, although it includes many contributions from others.
    146 
    147   In 1995, Guido continued his work on Python at the Corporation for
    148   National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
    149   in Reston, Virginia where he released several versions of the
    150   software.
    151 
    152   In May 2000, Guido and the Python core development team moved to
    153   BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
    154   year, the PythonLabs team moved to Digital Creations (now Zope
    155   Corporation, see http://www.zope.com).  In 2001, the Python Software
    156   Foundation (PSF, see http://www.python.org/psf/) was formed, a
    157   non-profit organization created specifically to own Python-related
    158   Intellectual Property.  Zope Corporation is a sponsoring member of
    159   the PSF.
    160 
    161   All Python releases are Open Source (see http://www.opensource.org for
    162   the Open Source Definition).  Historically, most, but not all, Python
    163   releases have also been GPL-compatible; the table below summarizes
    164   the various releases.

    201   Footnotes:
    202 
    203   (1) GPL-compatible doesn't mean that we're distributing Python under
    204       the GPL.  All Python licenses, unlike the GPL, let you distribute
    205       a modified version without making your changes open source.  The
    206       GPL-compatible licenses make it possible to combine Python with
    207       other software that is released under the GPL; the others don't.
    208 
    209   (2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
    210       because its license has a choice of law clause.  According to
    211       CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
    212       is "not incompatible" with the GPL.
    213 
    214   Thanks to the many outside volunteers who have worked under Guido's
    215   direction to make these releases possible.

    329   2. Subject to the terms and conditions of this License Agreement, CNRI
    330   hereby grants Licensee a nonexclusive, royalty-free, world-wide
    331   license to reproduce, analyze, test, perform and/or display publicly,
    332   prepare derivative works, distribute, and otherwise use Python 1.6.1
    333   alone or in any derivative version, provided, however, that CNRI's
    334   License Agreement and CNRI's notice of copyright, i.e., "Copyright (c)
    335   1995-2001 Corporation for National Research Initiatives; All Rights
    336   Reserved" are retained in Python 1.6.1 alone or in any derivative
    337   version prepared by Licensee.  Alternately, in lieu of CNRI's License
    338   Agreement, Licensee may substitute the following text (omitting the
    339   quotes): "Python 1.6.1 is made available subject to the terms and
    340   conditions in CNRI's License Agreement.  This Agreement together with
    341   Python 1.6.1 may be located on the Internet using the following
    342   unique, persistent identifier (known as a handle): 1895.22/1013.  This
    343   Agreement may also be obtained from a proxy server on the Internet
    344   using the following URL: http://hdl.handle.net/1895.22/1013".
    345 
    346   3. In the event Licensee prepares a derivative work that is based on
    347   or incorporates Python 1.6.1 or any part thereof, and wants to make
    348   the derivative work available to others as provided herein, then
    349   Licensee hereby agrees to include in any such work a brief summary of
    350   the changes made to Python 1.6.1.
    351 
    352   4. CNRI is making Python 1.6.1 available to Licensee on an "AS IS"
    353   basis.  CNRI MAKES NO REPRESENTATIONS OR WARRANTIES, EXPRESS OR
    354   IMPLIED.  BY WAY OF EXAMPLE, BUT NOT LIMITATION, CNRI MAKES NO AND
    355   DISCLAIMS ANY REPRESENTATION OR WARRANTY OF MERCHANTABILITY OR FITNESS
    356   FOR ANY PARTICULAR PURPOSE OR THAT THE USE OF PYTHON 1.6.1 WILL NOT
    357   INFRINGE ANY THIRD PARTY RIGHTS.
    358 
    359   5. CNRI SHALL NOT BE LIABLE TO LICENSEE OR ANY OTHER USERS OF PYTHON
    360   1.6.1 FOR ANY INCIDENTAL, SPECIAL, OR CONSEQUENTIAL DAMAGES OR LOSS AS
    361   A RESULT OF MODIFYING, DISTRIBUTING, OR OTHERWISE USING PYTHON 1.6.1,
    362   OR ANY DERIVATIVE THEREOF, EVEN IF ADVISED OF THE POSSIBILITY THEREOF.
    363 
    364   6. This License Agreement will automatically terminate upon a material
    365   breach of its terms and conditions.
    366 
    367   7. This License Agreement shall be governed by the federal
    368   intellectual property law of the United States, including without
    369   limitation the federal copyright law, and, to the extent such
    370   U.S. federal law does not apply, by the law of the Commonwealth of
    371   Virginia, excluding Virginia's conflict of law provisions.
    372   Notwithstanding the foregoing, with regard to derivative works based
    373   on Python 1.6.1 that incorporate non-separable material that was
    374   previously distributed under the GNU General Public License (GPL), the
    375   law of the Commonwealth of Virginia shall govern this License
    376   Agreement only as to issues arising under or with respect to
    377   Paragraphs 4, 5, and 7 of this License Agreement.  Nothing in this
    378   License Agreement shall be deemed to create any relationship of
    379   agency, partnership, or joint venture between CNRI and Licensee.  This
    380   License Agreement does not grant permission to use CNRI trademarks or
    381   trade name in a trademark sense to endorse or promote products or
