        sum -r RedHat60.img
    Method 2: compare checksums:
        cksum /dev/cdrom

        -o <file>   Output file name
        -path-list <file>   list of paths to include
        -x path  - exclude path (can use globbing)

    <do something>
    mkisofs -pad -l -r -J -v -V "gnoppix" -b CREDATIV/boot.img -c CREDATIV/boot.cat -hide-rr-moved -o gnoppix-0.5.4-1-en.iso /somewhere_else

DVDs
        utils
                regionselect
    regionset - view and modify the region code of DVD drives
    Regionset is a small utility which displays and sets the
    region/zone setting of a DVD drive, allowing it to decrypt the
    DVD's sold in this geographical zone. Hardware vendors often limit
    the number of such modifications, but it is necessary to set it at
    least once with a brand new drive.
