* $Log: client.c,v $
+ * Revision 1.12 2001/12/29 20:18:18 alex
+ * - neue Funktion Client_SetHostname().
+ *
+ * Revision 1.11 2001/12/29 03:10:47 alex
+ * - Client-Modes implementiert; Loglevel mal wieder angepasst.
+ *
+ * Revision 1.10 2001/12/27 19:13:47 alex
+ * - neue Funktion Client_Search(), besseres Logging.
+ *
