+ * was written by the process.
+ * Aditionally one may set raw stdout and stdin handling using the stdin() and stdout() methods
+ * to get the process' file descriptors.
+ * Last but not least K3bProcess is able to duplicate stdout making it possible to connect two 
+ * K3bProcesses like used in K3bDataJob to duplicate mkisofs' stdout to the stdin of the writer 
+ * (cdrecord or cdrdao)
