[NTG-context] [feature] update

I do a daily update of the context distribution using the command sh ./first-setup.sh --modules=all --engine=luatex This works well, but is rather verbose on the screen. Would it be possible to have a less verbose version? Or that the script could check some kind of a checksum before deciding to download all data? Or download only part of the data (saving on some carbon footprint ;-) Thanks. .Floris
