+vol_id - probe filesystem and read label and uuid
 
 This program is normally called from a udev rule, to provide udev with the
-name, uuid or the filesystem type of a volume to name a device node.
-vol_id opens the blockdevice node specified at the commandline.
-The following commandline switches are supported to specify what vol_id
-should print:
+filesystem type of a volume and the label and uuid to name a device node.
