  1. A. HISTORY OF THE SOFTWARE
  2. ==========================
  3. Python was created in the early 1990s by Guido van Rossum at Stichting
  4. Mathematisch Centrum (CWI) in the Netherlands as a successor of a
  5. language called ABC. Guido is Python's principal author, although it
  6. includes many contributions from others. The last version released
  7. from CWI was Python 1.2. In 1995, Guido continued his work on Python
  8. at the Corporation for National Research Initiatives (CNRI) in Reston,
  9. Virginia where he released several versions of the software. Python
  10. 1.6 was the last of the versions released by CNRI. In 2000, Guido and
  11. the Python core development team moved to BeOpen.com to form the
  12. BeOpen PythonLabs team. Python 2.0 was the first and only release
  13. from BeOpen.com.
  14. Following the release of Python 1.6, and after Guido van Rossum left
  15. CNRI to work with commercial software developers, it became clear that
  16. the ability to use Python with software available under the GNU Public
  17. License (GPL) was very desirable. CNRI and the Free Software
  18. Foundation (FSF) interacted to develop enabling wording changes to the
  19. Python license. Python 1.6.1 is essentially the same as Python 1.6,
  20. with a few minor bug fixes, and with a different license that enables
  21. later versions to be GPL-compatible. Python 2.1 is a derivative work
  22. of Python 1.6.1, as well as of Python 2.0.
  23. After Python 2.0 was released by BeOpen.com, Guido van Rossum and the
  24. other PythonLabs developers joined Digital Creations. All
  25. intellectual property added from this point on, starting with Python
  26. 2.1 and its alpha and beta releases, is owned by the Python Software
  27. Foundation (PSF), a non-profit modeled after the Apache Software
  28. Foundation. See http://www.python.org/psf/ for more information about
  29. the PSF.
  30. Thanks to the many outside volunteers who have worked under Guido's
  31. direction to make these releases possible.
