10 History of the software
11 =======================
13 Python was created in the early 1990s by Guido van Rossum at Stichting
14 Mathematisch Centrum (CWI, see http://www.cwi.nl/) in the Netherlands as a
15 successor of a language called ABC. Guido remains Python's principal author,
16 although it includes many contributions from others.
18 In 1995, Guido continued his work on Python at the Corporation for National
19 Research Initiatives (CNRI, see http://www.cnri.reston.va.us/) in Reston,
20 Virginia where he released several versions of the software.
22 In May 2000, Guido and the Python core development team moved to BeOpen.com to
23 form the BeOpen PythonLabs team. In October of the same year, the PythonLabs
24 team moved to Digital Creations (now Zope Corporation; see
25 http://www.zope.com/). In 2001, the Python Software Foundation (PSF, see
26 http://www.python.org/psf/) was formed, a non-profit organization created
27 specifically to own Python-related Intellectual Property. Zope Corporation is a
28 sponsoring member of the PSF.
30 All Python releases are Open Source (see http://www.opensource.org/ for the Open
31 Source Definition). Historically, most, but not all, Python releases have also
32 been GPL-compatible; the table below summarizes the various releases.

102 GPL-compatible doesn't mean that we're distributing Python under the GPL. All
103 Python licenses, unlike the GPL, let you distribute a modified version without
104 making your changes open source. The GPL-compatible licenses make it possible to
105 combine Python with other software that is released under the GPL; the others
108 Thanks to the many outside volunteers who have worked under Guido's direction to
109 make these releases possible.
