mapansi.c - converts a string to input events using MapANSI() function.

            This example will also take the created input events
            and add them to the input stream using the simple
            commodities.library function AddIEvents().  Alternately,
            you could open the input.device and use the input device
            command IND_WRITEEVENT to add events to the input stream.
