+         This device-mapper target emulates a block device that has
+         additional per-sector tags that can be used for storing
+         integrity information.
+
+         This integrity target is used with the dm-crypt target to
+         provide authenticated disk encryption or it can be used
+         standalone.
+
+         To compile this code as a module, choose M here: the module will
+         be called dm-integrity.
