+The Berkeley Database (Berkeley DB) is a programmatic toolkit that
+provides embedded database support for both traditional and
+client/server applications. The Berkeley DB includes B+tree, Extended
+Linear Hashing, Fixed and Variable-length record access methods,
+transactions, locking, logging, shared memory caching, and database
+recovery. The Berkeley DB supports C, C++, Java, and Perl APIs. It is
+used by many applications, including Python and Perl, so this should
+be installed on all systems.
