* =====================================================================
* ToDo: XML-Backend: Automatic reload if something was changed...
*
*
* =====================================================================
* Version: $Id$
* =====================================================================
* History:
* $Log$
* Revision 1.4 2002/10/14 16:21:54 eilers
* Some minor interface updates
*
* Revision 1.3 2002/10/07 17:34:24 eilers
* added OBackendFactory for advanced backend access
*
* 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 !
