-	  EFS is an older file system used for non-ISO9660 CD-ROMs and hard
-	  disk partitions by SGI's IRIX operating system (IRIX 6.0 and newer
-	  uses the XFS file system for hard disk partitions however).
-
-	  This implementation only offers read-only access. If you don't know
-	  what all this is about, it's safe to say N. For more information
-	  about EFS see its home page at <http://aeschi.ch.eu.org/efs/>.
-
-	  To compile the EFS file system support as a module, choose M here: the
-	  module will be called efs.
