Well as i said it's more to see when they tampered with the config or 
the program. It's not a commercial application but it's for inhouse use 
in the hospital where i work. These people are, to put it mildly, not 
the most computer savant people around.
It could be handy to avoid me searching for a solution to a problem that 
arises because of messing with the setup rather than a bug in the code.
