+Controls detection and subsequent wiping of signatures on newly created
+Logical Volume. There's a prompt for each signature detected to confirm
+its wiping (unless \fB--yes\fP is used where LVM assumes 'yes' answer
+for each prompt automatically). If this option is not specified, then by
+default \fB-W\fP | \fB--wipesignatures y\fP is assumed each time the
+zeroing is done (\fB\-Z\fP | \fB\-\-zero y\fP). This default behaviour
 can be controlled by \fB\%allocation/wipe_signatures_when_zeroing_new_lvs\fP
 setting found in
 .BR lvm.conf (5).
