    That's a good point @greghogan. We don't have a standard way to print a usage message.
A disadvantage of the approach in this PR is that we will display an error message which might
actually mask any usage information printed. An alternative approach would be to simply exit
(perhaps with a small hint). That might actually be nicer.

This is not a big issue but should be changed to something more descriptive.
