+# Usage:
+# disk_stress_ng [ <device-filename> ]
+# [ --base-time <time-in-seconds> ]
+# [ --really-run ]
+#
+# Parameters:
+# --disk-device -- This is the WHOLE-DISK device filename WITHOUT "/dev/"
+# (e.g., sda). The script finds a filesystem on that
+# device, mounts it if necessary, and runs the tests on
+# that mounted filesystem.
+# Test with iostat
