    longDescription =
      '' Tokyo Cabinet is a library of routines for managing a database. The
         database is a simple data file containing records, each is a pair of
         a key and a value.  Every key and value is serial bytes with
         variable length.  Both binary data and character string can be used
         as a key and a value.  There is neither concept of data tables nor
         data types.  Records are organized in hash table, B+ tree, or
         fixed-length array.

         Tokyo Cabinet is developed as the successor of GDBM and QDBM on the
         following purposes.  They are achieved and Tokyo Cabinet replaces
         conventional DBM products: improves space efficiency, improves time
         efficiency, improves parallelism, improves usability, improves
         robustness, supports 64-bit architecture.
