Too bad it took over a decade (two?) before someone tried to sort out
that misuse of the metric system. And they still have got nowhere after
a decade too. Looks like the computing world don't care what the rest of
the world thinks. Typical eh?

Yawn. Please go rap something like the UNIX definition.

Likewise, just pointing out these bodies makes no sense to me. Get this
into the POSIX standard and then I'd be happy as a fish in water. Except
for the part where I have to talk like a frog. Gribbit.
