A relatively primitive (but working) Haskell library to read and write BBDB (Insidious Big Brother Database) files. One major goal was to be able to have the following be the identity function:
d <- readBBDB "/path/to/.bbdb" -- d is now a Haskell data type writeFile (asLisp d) "path/to/copy-of-.bbdb"
Because of this goal, the interface is based on lists, and tends to be a lot of work to get to the actual data you are looking for. Sorry about that.
