Hello @swiftyfinch,
thank you very much for creating a Pull Request!
Here is a small checklist to get this PR merged as quickly as possible:

• Do all subcommands / options which take arguments include the args property (args: {})?
• Are all options modular? E.g. -a -u -x instead of -aux
• Have all other checks passed?

Please add a 👍 as a reaction to this comment to show that you read this.

Looks good to me! Quick question, did you write the spec by hand or was there some swift generator you used?
