+/*
+* 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

+* 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.
