       +Usage
       +-----
       +1. Connect the IR-tower via a serial-to-usb adapter.  Check that the
       +tower has a working 9V battery.
       +
       +2. Install nqc (in AUR, may need manual build)
       +
       +3. Find a Lego RCX, turn it on, and upload the firmware, which will take
       +a few minutes while the RCX counts up to high numbers.  The IR tower
       +will light a green LED while sending data:
       +
       +        $ make upload_firmware
       +
       +4. Upload the program:
       +
       +        $ make upload
       +
       +Note: The RCX will not remember the program and forget the firmware if
       +powered off and without batteries.
