Usage:
    python hex2bin.py [options] INFILE [OUTFILE]

Arguments:
    INFILE      name of hex file for processing.
    OUTFILE     name of output file. If omitted then output
                will be writing to stdout.

Options:
    -h, --help              this help message.
    -v, --version           version info.
    -p, --pad=FF            pad byte for empty spaces (ascii hex value).
    -r, --range=START:END   specify address range for writing output
                            (ascii hex value).
                            Range can be in form 'START:' or ':END'.
    -l, --length=NNNN,
    -s, --size=NNNN         size of output (decimal value).
