Overview

The monovm-whois command.

Kept as a class taking explicit +stdout+/+stderr+ and returning an exit code rather than calling exit itself, so the specs can run it in-process and assert on its output.

Exit codes: 0 when every name got a real answer, 1 when any came back unknown or invalid, 2 for a usage error.
