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'.
