-- | Pure Haskell key/value store implementation
--   
--   A simple bytestring key/value store implemented in terms of hash table
--   over a file. It cannot yet grow/shrink the hash table as needed, nor
--   does it free old unused (key,value) pair storage. Mostly useful for
--   applications that need not worry about the size of their persistent
--   store. Reduces dependency hell.
