Along the same lines, we've been talking about the interface to the script 
for the VI device itself.
Traditionally, you'd just pass options, like this:
delcomVI --red on --bflash --gflash 5,2 --gsync 3 --sync --buzzer on --buzzer-repeat 3

But there are so many options that way (there are multiple options for each 
color LED, plus the buzzer, plus different bits of information to read), 
that it gets really confusing.

Wayne suggested a language route:
$ delcomVI
> red on
> blue flash
> green flash on:5 off:2 syncoffset:3
> buzzer on repeat:3

or
$ delcomVI 'red on' blue flash' 'green flash on:5 off:2 syncoffset:3' 'buzzer on repeat:3'

I thought maybe a compromise would be good:

delcomVI --red,on --blue,flash --green,flash,on=5,off=2,syncoffset=3 --buzzer,on,repeat=3

Any suggestions?
