> When invoked without the command or sub-command, _ozone oz_ prints the
> following error:
> {code:java}
> $ ozone oz
> Please select a subcommand
> {code}
> and
> {code:java}
> $ ozone oz volume
> Please select a subcommand
> {code}
> For most familiar with Unix utilities it is obvious they should rerun the
> command with _--help._ However we can just print the usage instead to avoid
> guesswork
