Gag, that would really be ugly code ;-)

If anything I might actually want to break up the perl script. This was 
just made to be an example. Any serious user would most likely write their 
own user apps. This was more of a proof of concept.

I could clean up that code, and then have one big file that does all the 
ugliness for those that just want to tinker with it. But that is low on 
the totem pole ;-)
