+Usage:  $ME [-h] [-t FSTYPE] DEVICE
+
+Prepare DEVICE to be used in volumes.
+DEVICE is the special file corresponding to the
+device (e.g /dev/sdXX).
+
+General:
+  -t FSTYPE                 Prepare DEVICE using FSTYPE filesystem.
+                            Supported filesystems are ext3/ext4/xfs
+                            (Default is ext4/ext3)
+
+Miscellaneous:
+  -h                        display this help and exit
