	---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/
