Convert the description comment at the top of the file to a documentation string. That string then maybe viewed with the --help argument. Also, rework a bit the documentation string: remove usage, since that is provided by the help message of the argparse module. Signed-off-by: Ruslan Mstoi <ruslan.mstoi@intel.com>
