I meant dmesg. (Don't build wget right now, it's in pieces. It's one of
the ones I'm rewriting but I spent ~2 months distracted by $DAYJOB being
in permanent crisis mode and am just now carving out some time to try to
get some momentum going again here. Said time might possibly be carved
out of my sleep schedule.)

Sigh. I need to upgrade the help text generator too. It _should_ be able
