Apparently it's quite easy to make intelligible error messages by
combining words:

(no index)
(no key)
(no file)
(no host)
(no process)

(wrong arg)
(wrong file)

(too few arg)
(too many arg)

We've gone right past re-inventing the wheel and re-invented language.

The downside is that these are (no longer funny) :-)
