+ * Handwritten code to wrap version 3.x of the Berkeley DB library,
+ * written to replace a SWIG-generated file.
+ *
+ * This module was started by Andrew Kuchling to remove the dependency
+ * on SWIG in a package by Gregory P. Smith <greg@electricrain.com> 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 has now returned full circle back to
+ * Robin Dunn who is working in behalf of Digital Creations to complete
+ * the wrapping of the DB 3.x API and to build a solid unit test suite.
+ *
+ * This module contains 5 types:
+ *
+ * DB (Database)
+ * DBCursor (Database Cursor)
+ * DBEnv (database environment)
+ * DBTxn (An explicit database transaction)
+ * DBLock (A lock handle)
+ *
+ */
+
+/* --------------------------------------------------------------------- */
+
+/*
+ * 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.
+ *
+ * --Robin
+ *
+ * All I've done is steal the bsddb3-3.3.1 code, and changed "bsddb3" to
+ * "rpmdb" and "_db" to "_rpmdb" in order to avoid symbol conflicts.
+ *
+ * bsddb3 is Nice Stuff, I couldn't possibly do a better job.
+ *
+ * --Jeff
