+ * whole stuff.
+ * Thus, PIM-Database backend is finished, but highly experimental. And some
+ * parts are still generic. For instance, the "queryByExample()" methods are
+ * not (or not fully) implemented. Todo: custom-entries not stored.
+ * The big show stopper: matchRegExp() (needed by OpieSearch) needs regular

+ * Therefore we need either an extended sqlite or a workaround which would
+ * be very slow and memory consuming..
