 Sleepycat Software has provided MySQL with the Berkeley DB
 transactional storage engine. This storage engine typically is called
 `BDB' for short. `BDB' tables may have a greater chance of surviving
 crashes and are also capable of `COMMIT' and `ROLLBACK' operations on
 transactions.
 
 Support for the `BDB' storage engine is included in MySQL source
 distributions is activated in MySQL-Max binary distributions. The MySQL
 source distribution comes with a `BDB' distribution that is patched to
 make it work with MySQL. You cannot use a non-patched version of `BDB'
 with MySQL.
 
 We at MySQL AB work in close cooperation with Sleepycat to keep the
 quality of the MySQL/BDB interface high. (Even though Berkeley DB is in
 itself very tested and reliable, the MySQL interface is still
 considered gamma quality. We continue to improve and optimize it.)
 
 When it comes to support for any problems involving `BDB' tables, we
 are committed to helping our users locate the problem and create
 reproducible test cases. Any such test case is forwarded to Sleepycat,
 which in turn helps us find and fix the problem. As this is a two-stage
 operation, any problems with `BDB' tables may take a little longer for
 us to fix than for other storage engines. However, we anticipate no
 significant difficulties with this procedure because the Berkeley DB
 code itself is used in many applications other than MySQL.
