Cisco Cisco IPICS Release 2.1 Licensing Information

 

This is the official license for the Python 2.2.1 release:       

      

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 (see       

http://www.digicool.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.  Digital Creations 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.
