1A. HISTORY OF THE SOFTWARE
2==========================
3
4Python was created in the early 1990s by Guido van Rossum at Stichting
5Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
6as a successor of a language called ABC. Guido remains Python's
7principal author, although it includes many contributions from others.
8
9In 1995, Guido continued his work on Python at the Corporation for
10National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
11in Reston, Virginia where he released several versions of the
12software.
13
14In May 2000, Guido and the Python core development team moved to
15BeOpen.com to form the BeOpen PythonLabs team. In October of the same
16year, the PythonLabs team moved to Digital Creations (now Zope
17Corporation, see http://www.zope.com). In 2001, the Python Software
18Foundation (PSF, see http://www.python.org/psf/) was formed, a
19non-profit organization created specifically to own Python-related
20Intellectual Property. Zope Corporation is a sponsoring member of
21the PSF.
22
23All Python releases are Open Source (see http://www.opensource.org for
24the Open Source Definition). Historically, most, but not all, Python
25releases have also been GPL-compatible; the table below summarizes
26the various releases.

57Footnotes:
58
59(1) GPL-compatible doesn't mean that we're distributing Python under
60 the GPL. All Python licenses, unlike the GPL, let you distribute
61 a modified version without making your changes open source. The
62 GPL-compatible licenses make it possible to combine Python with
63 other software that is released under the GPL; the others don't.
64
65(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
66 because its license has a choice of law clause. According to
67 CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
68 is "not incompatible" with the GPL.
69
70Thanks to the many outside volunteers who have worked under Guido's
71direction to make these releases possible.
