Thank's for your help - we could even combine this with the next dump for the time being, however my idea would be to have device, which does not have kual installed

Despite its great utility it is difficult to explain to 80 year old what kual is and does, so I really would like to have something which simply runs and is not really visible to the user... Not sure that I will be able to achieve this, but (time permitting) will try.
I updated my package (I think I found some problems with error processing)
