+          This is a driver for SCSI media changers.  Most common devices are
+          tape libraries and MOD/CDROM jukeboxes.  *Real* jukeboxes, you
+          don't need this for those tiny 6-slot cdrom changers.  Media
+          changers are listed as "Type: Medium Changer" in /proc/scsi/scsi.
+          If you have such hardware and want to use it with linux, say Y
+          here.  Check <file:Documentation/scsi-changer.txt> for details.
+        
+          If you want to compile this as a module ( = code which can be
+          inserted in and removed from the running kernel whenever you want),
+          say M here and read <file:Documentation/modules.txt> and
+          <file:Documentation/scsi.txt>. The module will be called ch.o.
+          If unsure, say N.
