paul@0 | 1 | A. HISTORY OF THE SOFTWARE |
paul@0 | 2 | ========================== |
paul@0 | 3 | |
paul@0 | 4 | Python was created in the early 1990s by Guido van Rossum at Stichting |
paul@0 | 5 | Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands |
paul@0 | 6 | as a successor of a language called ABC. Guido remains Python's |
paul@0 | 7 | principal author, although it includes many contributions from others. |
paul@0 | 8 | |
paul@0 | 9 | In 1995, Guido continued his work on Python at the Corporation for |
paul@0 | 10 | National Research Initiatives (CNRI, see http://www.cnri.reston.va.us) |
paul@0 | 11 | in Reston, Virginia where he released several versions of the |
paul@0 | 12 | software. |
paul@0 | 13 | |
paul@0 | 14 | In May 2000, Guido and the Python core development team moved to |
paul@0 | 15 | BeOpen.com to form the BeOpen PythonLabs team. In October of the same |
paul@0 | 16 | year, the PythonLabs team moved to Digital Creations (now Zope |
paul@0 | 17 | Corporation, see http://www.zope.com). In 2001, the Python Software |
paul@0 | 18 | Foundation (PSF, see http://www.python.org/psf/) was formed, a |
paul@0 | 19 | non-profit organization created specifically to own Python-related |
paul@0 | 20 | Intellectual Property. Zope Corporation is a sponsoring member of |
paul@0 | 21 | the PSF. |
paul@0 | 22 | |
paul@0 | 23 | All Python releases are Open Source (see http://www.opensource.org for |
paul@0 | 24 | the Open Source Definition). Historically, most, but not all, Python |
paul@0 | 25 | releases have also been GPL-compatible; the table below summarizes |
paul@0 | 26 | the various releases. |

paul@0 | 68 | Footnotes: |
paul@0 | 69 | |
paul@0 | 70 | (1) GPL-compatible doesn't mean that we're distributing Python under |
paul@0 | 71 | the GPL. All Python licenses, unlike the GPL, let you distribute |
paul@0 | 72 | a modified version without making your changes open source. The |
paul@0 | 73 | GPL-compatible licenses make it possible to combine Python with |
paul@0 | 74 | other software that is released under the GPL; the others don't. |
paul@0 | 75 | |
paul@0 | 76 | (2) According to Richard Stallman, 1.6.1 is not GPL-compatible, |
paul@0 | 77 | because its license has a choice of law clause. According to |
paul@0 | 78 | CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1 |
paul@0 | 79 | is "not incompatible" with the GPL. |
paul@0 | 80 | |
paul@0 | 81 | Thanks to the many outside volunteers who have worked under Guido's |
paul@0 | 82 | direction to make these releases possible. |
