-	  'makedevs' is a utility used to create a batch of devices with
-	  one command.
-	  .
-	  There are two choices for command line behaviour, the interface
-	  as used by LEAF/Linux Router Project, or a device table file.
-	  . 
-	  'leaf' is traditionally what busybox follows, it allows multiple
-	  devices of a particluar type to be created per command.
-	  e.g. /dev/hda[0-9]
-          Device properties are passed as command line arguments.
-	  .
-	  'table' reads device properties from a file or stdin, allowing
-	  a batch of unrelated devices to be makde with one command. 
-          User/group names are allowed as an alternative to uid/gid.
