- * Handwritten code to wrap version 3.x of the Berkeley DB library,
- * written to replace a SWIG-generated file.  It has since been updated
- * to compile with Berkeley DB versions 3.2 through 4.2.
- *
- * This module was started by Andrew Kuchling to remove the dependency
- * on SWIG in a package by Gregory P. Smith who based his work on a
- * similar package by Robin Dunn <robin@alldunn.com> which wrapped
- * Berkeley DB 2.7.x.
- *
- * Development of this module then returned full circle back to Robin Dunn
- * who worked on behalf of Digital Creations to complete the wrapping of
- * the DB 3.x API and to build a solid unit test suite.  Robin has
- * since gone onto other projects (wxPython).
- *
- * Gregory P. Smith <greg@krypto.org> was once again the maintainer.
- *
- * Since January 2008, new maintainer is Jesus Cea <jcea@jcea.es>.
- * Jesus Cea licenses this code to PSF under a Contributor Agreement.
- *
- * Use the pybsddb-users@lists.sf.net mailing list for all questions.
- * Things can change faster than the header of this file is updated.  This
- * file is shared with the PyBSDDB project at SourceForge:
- *
- * http://pybsddb.sf.net
- *
- * This file should remain backward compatible with Python 2.1, but see PEP
- * 291 for the most current backward compatibility requirements:
- *
- * http://www.python.org/peps/pep-0291.html
- *
- * This module contains 6 types:
- *
- * DB           (Database)
- * DBCursor     (Database Cursor)
- * DBEnv        (database environment)
- * DBTxn        (An explicit database transaction)
- * DBLock       (A lock handle)
- * DBSequence   (Sequence)
- *

-/*
- * Portions of this module, associated unit tests and build scripts are the
- * result of a contract with The Written Word (http://thewrittenword.com/)
- * Many thanks go out to them for causing me to raise the bar on quality and
- * functionality, resulting in a better bsddb3 package for all of us to use.
