+//============================================================================
+// Name:
+//   mkidemo.cpp
+//
+// Summary:
+//   Extremly simple demo program that shows some values
+//   on the mercedes combi instrument. needs libcanio to work.
+//
+//   Default interface is can0, to change it start the program like this:
+//     mkidemo -f=can1
+//
+// Created on:
+//   Okt 1, 2010
+//
+// Author:
+//   Christian Steiger
