leveldb-haskell (hackage): From http://code.google.com/p/snappy:  LevelDB is a fast key-value storage library written at Google that provides an ordered mapping from string keys to string values.  This library provides a Haskell language binding to LeveldDB. It is in very early stage and has seen very limited testing.  Note: as of v1.3, LevelDB can be built as a shared library. Thus, as of v0.1.0 of this library, LevelDB is no longer bundled and must be installed on the target system (version 1.7 or greater is required).
