+- '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.
