+Options:

+   -v,     --version      <version>   PSU FW version
+   -model, --model        <model>     PSU FW model
+   -mf,    --manufacture  <version>   PSU FW manufacture
+   -o,     --outfile      <filename>  Outfile name
+			              For example : -o psufw.tar
+                                      The default outfile name is image.tar,and

+                                      open-source private key in this script.
