	A. HISTORY OF THE SOFTWARE
	==========================

	contextlib2 is a derivative of the contextlib module distributed by the PSF
	as part of the Python standard library. According, it is itself redistributed
	under the PSF license (reproduced in full below). As the contextlib module
	was added only in Python 2.5, the licenses for earlier Python versions are
	not applicable and have not been included.

	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 that included the contextlib module.

	Footnotes:

	(1) 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.
