| History and License |

| |
| 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. |

| |
| 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. |
