 * @brief    This function implements the trace for debug tests
 * @note    This implementation uses printf. First the variables are retrieved using
 *            ANSI C defs and macros which enable to access a variable number of arguments.
 *            Then the printf is done (with some ornemental adds).
 * @param    level (IN): the debug level
 * @param    format (IN): the "printf" formated string
 * @param    ... (IN): as many parameters as required ...
 * @return    none
