Replacing Berkeley Db with Sqlite

I have replaced Berkeley Db with Sqlite.
Reasons are twofold:
(a) There is very little documentation on
Berkeley Db and hence the code is very
prone to error.
(b) Berkeley requires 2.5 Mb for 50,000
records on two fields; Sqlite requires only
1.4 Mb for 50,000 records on three fields

At the moment there are no releases yet,
but if you would like the source code, let
me know.
