information in less lines.

-          This is a host adapter simulator that can simulate multiple hosts
-          each with multiple dummy SCSI devices (disks). It defaults to one
-          host adapter with one dummy SCSI disk. Each dummy disk uses kernel
-          RAM as storage (i.e. it is a ramdisk). To save space when multiple
-          dummy disks are simulated, they share the same kernel RAM for 
-          their storage. See <http://sg.danny.cz/sg/sdebug26.html> for more
-          information. This driver is primarily of use to those testing the
-          SCSI and block subsystems. If unsure, say N.
