 * Info: This class could just work with a change in the header-file

 * =====================================================================
 * ToDo: XML-Backend: Automatic reload if something was changed...
 *
 *
 * =====================================================================
 * Version: $Id$
 * =====================================================================
 * History:
 * $Log$
 * Revision 1.2  2002/10/02 16:18:11  eilers
 * debugged and seems to work almost perfectly ..
 *
 * Revision 1.1  2002/09/27 17:11:44  eilers
 * Added API for accessing the Contact-Database ! It is compiling, but
 * please do not expect that anything is working !
 * I will debug that stuff in the next time ..
 * Please read README_COMPILE for compiling !
