+    """Execute Unixbench cpu benchmark in a host
+    The Run script takes a number of options which you can use to customise a
+    test, and you can specify the names of the tests to run.  The full usage
+    is:
+
+    Run [ -q | -v ] [-i <n> ] [-c <n> [-c <n> ...]] [test ...]
+
+    -i <count>    Run <count> iterations for each test -- slower tests
+                use <count> / 3, but at least 1.  Defaults to 10 (3 for
+                slow tests).
+    -c <n>        Run <n> copies of each test in parallel.
+
+    Parameters for setting unixbench
+        run_mode - Run in quiet mode or verbose mode
