    <para>The GDBM package contains the GNU Database Manager.  It is a library
    of database functions that use extensible hashing and work similar to the
    standard UNIX dbm.  The library provides primitives for storing key/data
    pairs, searching and retrieving the data by its key and deleting a key
    along with its data. </para>
