+ * 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.
