+
+=head2 C<db_open()>
+
+open DB.
+It uses tie() to bind a hash to a DB file.
+Our minimal_states uses several DB files for
+C<%ticket_id>,
+C<%date>,
+C<%status>,
+C<%sender>,
+C<%articles>,
+C<%message_id>
+and
+C<%index>.
+
+=head2 C<db_close()>
+
+untie() corresponding hashes opened by C<db_open()>.
