AW: Command line argument files


Thank you for your suggestion.
But I think we shouldn’t add a new dependency for replacing code, that works and was touched last time 8 months ago ('just' introducing some Java8 stuff), then 2 years ago (no FileInput/OutputStream::new) then 4 years ago ...

So maintenance is no real point here.
