+         This device-mapper target creates a device that supports an arbitrary
+         mapping of fixed-size regions of I/O across a fixed set of paths.
+         The path used for any specific region can be switched dynamically
+         by sending the target a message.
+
+         To compile this code as a module, choose M here: the module will
+         be called dm-switch.
