I have written two small, simple modules to address limitations I found 
in in Grub.

1. does simple arithmetic - nothing fancy. It's invoked by using 
something like this:

insmod arithmetic
arithmetic --set fred --min 2 -- max 10 "1" "+" "2"

the operators supported are unary -,!; binary +,-,/,*,%,<,<=,<.<=,!=,==
--set works in the usual way. If the result is greater than --max, the 
--min value is returned and vice versa; this useful for cycling round a 
group of partitions in a round-robin fashion

2. diskinfo.mod introduces two commands: disklabel, diskuuid which 
return the label and uuid of the specified disk partition. This is 
useful where, having decided which partition, amongst several, to boot, 
you can fill in the appropriate value in the "root=UUID=" or 
"root=label=" Linux kernel parameter.

I looked for details on how to submit new modules, but failed to find 
anything. How do I go about this?
