    ===============================================================

    Key software for making use of tools like KyroFlux and SuperCard Pro with
    Atari disks and disk images:

    a8rawconv by Avery Lee, 2014-2016
    ---------
    - Convert from a raw disk image (RAW or SCP) produced by imaging hardware to a
    decoded Atari disk image (ATR or ATX). Raw images can be produced from
    physical floppy disks either by KryoFlux or SuperCard Pro imaging hardware. - Convert between ATR and ATX (either direction).
    - Convert from RAW to SCP.
    - Use a SuperCard Pro device to directly read from a floppy disk.
    - With a SuperCard Pro device, write images to physical disks.
