There is a windows-like solution for updating the wrapper. It first
prepares another script, istalls it to be run at startup and issues
the tradditional message "Windows need to be restarted". Upon restart
the auxilliary script will update the wrapper, remove itself from
startup and run the new wrapper. Hopefully a simple wrapper would not
need frequent updates.
