Thanks,
I tested this and it turns out to not showing anything at all until download is
done.
This is better than the overwhelming amount before but a little bit terse still.
Is there a way to reduce the output while still seeing some kind of progress
like the so far downloaded time?
If a running time output is constantly updated (on the same line) then one can
see the process is working but not flooding the screen...
