-Currently the tool will automatically try to detect which Super I/O you
-have, and also dump the register contents.
+ -d | --dump Dump Super I/O registers
+ -V | --verbose Verbose mode
+ -v | --version Show the superiotool version
+ -h | --help Show a short help text
+
+Per default (no options) superiotool will just probe for a Super I/O
+and print its vendor, name, ID, version, and config port.
+
+Typical usage of superiotool:
+
+ - Probe/detect the Super I/O in your mainboard:
+
+ $ superiotool
+
+ - Detailed register dump of the Super I/O (if detected):
+
+ $ superiotool -d
