+       ---help---
+         Cowloop is a "copy-on-write" pseudo block driver. It can be
+         stacked on top of a "real" block driver, and catches all write
+         operations on their way from the file systems layer above to
+         the real driver below, effectively shielding the lower driver
+         from those write accesses. The requests are then diverted to
+         an ordinary file, located somewhere else (configurable). Later
+         read requests are checked to see whether they can be serviced
+         by the "real" block driver below, or must be pulled in from
+         the diverted location. More information and userspace tools to
+         use the driver are on the project's website
+         http://www.ATComputing.nl/cowloop/
