I do *not* have *any* GUI routines or such.
The program was created as one of the console types Lazarus offers (I
do not really know the difference between them and I don't remember
which one I chose).
So it is *not* a GUI program at all, it was meant from the start to be
run from cron invisible from the user rather like a service.

I also set the dependencies to LCLbase to avoid the GUI part.
