Currently it says: --8<---------------cut here---------------start------------->8--- $ guix build --help | grep -e -verbo -v, --verbosity=LEVEL use the given verbosity LEVEL --8<---------------cut here---------------end--------------->8--- We could add “an integer between 0 and 2”, but this was left non-explicit in case we eventually extend it to -7 to +42. Maybe there’s a limit on what we can do to help users? :-) Ludo’.
