\section{History of the software} Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum (CWI, see \url{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 \url{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 \url{http://www.zope.com/}). In 2001, the Python Software Foundation (PSF, see \url{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 \url{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. \begin{tablev}{c|c|c|c|c}{textrm}% {Release}{Derived from}{Year}{Owner}{GPL compatible?} \linev{0.9.0 thru 1.2}{n/a}{1991-1995}{CWI}{yes} \linev{1.3 thru 1.5.2}{1.2}{1995-1999}{CNRI}{yes} \linev{1.6}{1.5.2}{2000}{CNRI}{no} \linev{2.0}{1.6}{2000}{BeOpen.com}{no} \linev{1.6.1}{1.6}{2001}{CNRI}{no} \linev{2.1}{2.0+1.6.1}{2001}{PSF}{no} \linev{2.0.1}{2.0+1.6.1}{2001}{PSF}{yes} \linev{2.1.1}{2.1+2.0.1}{2001}{PSF}{yes} \linev{2.2}{2.1.1}{2001}{PSF}{yes} \linev{2.1.2}{2.1.1}{2002}{PSF}{yes} \linev{2.1.3}{2.1.2}{2002}{PSF}{yes} \linev{2.2.1}{2.2}{2002}{PSF}{yes} \linev{2.2.2}{2.2.1}{2002}{PSF}{yes} \linev{2.2.3}{2.2.2}{2002-2003}{PSF}{yes} \linev{2.3}{2.2.2}{2002-2003}{PSF}{yes} \linev{2.3.1}{2.3}{2002-2003}{PSF}{yes} \linev{2.3.2}{2.3.1}{2003}{PSF}{yes} \linev{2.3.3}{2.3.2}{2003}{PSF}{yes} \linev{2.3.4}{2.3.3}{2004}{PSF}{yes} \linev{2.3.5}{2.3.4}{2005}{PSF}{yes} \linev{2.4}{2.3}{2004}{PSF}{yes} \linev{2.4.1}{2.4}{2005}{PSF}{yes} \linev{2.4.2}{2.4.1}{2005}{PSF}{yes} \linev{2.4.3}{2.4.2}{2006}{PSF}{yes} \linev{2.5}{2.4}{2006}{PSF}{yes} \linev{2.5.1}{2.5}{2007}{PSF}{yes} \end{tablev} \note{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.} Thanks to the many outside volunteers who have worked under Guido's direction to make these releases possible. \section{Terms and conditions for accessing or otherwise using Python} \centerline{\strong{PSF LICENSE AGREEMENT FOR PYTHON \version}} \begin{enumerate} \item This LICENSE AGREEMENT is between the Python Software Foundation (``PSF''), and the Individual or Organization (``Licensee'') accessing and otherwise using Python \version{} software in source or binary form and its associated documentation. \item Subject to the terms and conditions of this License Agreement, PSF hereby grants Licensee a nonexclusive, royalty-free, world-wide license to reproduce, analyze, test, perform and/or display publicly, prepare derivative works, distribute, and otherwise use Python \version{} alone or in any derivative version, provided, however, that PSF's License Agreement and PSF's notice of copyright, i.e., ``Copyright \copyright{} 2001-2006 Python Software Foundation; All Rights Reserved'' are retained in Python \version{} alone or in any derivative version prepared by Licensee. \item In the event Licensee prepares a derivative work that is based on or incorporates Python \version{} or any part thereof, and wants to make the derivative work available to others as provided herein, then Licensee hereby agrees to include in any such work a brief summary of the changes made to Python \version. \item PSF is making Python \version{} available to Licensee on an ``AS IS'' basis.

It does not include any code or documentation that is identified in the RFC as being copyrighted. The original and principal author of md5.h is L. Peter Deutsch <[email protected]>. Other authors are noted in the change history that follows (in reverse chronological order): 2002-04-13 lpd Removed support for non-ANSI compilers; removed references to Ghostscript; clarified derivation from RFC 1321; now handles byte order either statically or dynamically. 1999-11-04 lpd Edited comments slightly for automatic TOC extraction. 1999-10-18 lpd Fixed typo in header comment (ansi2knr rather than md5); added conditionalization for C++ compilation from Martin Purschke <[email protected]>. 1999-05-03 lpd Original version. \end{verbatim} \subsection{Asynchronous socket services} The \module{asynchat} and \module{asyncore} modules contain the following notice: \begin{verbatim} Copyright 1996 by Sam Rushing All Rights Reserved Permission to use, copy, modify, and distribute this software and its documentation for any purpose and without fee is hereby granted, provided that the above copyright notice appear in all copies and that both that copyright notice and this permission notice appear in supporting documentation, and that the name of Sam Rushing not be used in advertising or publicity pertaining to distribution of the software without specific, written prior permission.
