-          'makedevs' is a utility used and created by the Linux Router Project.
-          It creates a large number of device special files (/dev devices)
-          rather quickly, and can be considerably faster then running mknod a
-          zillion times.
+          '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.
