Thanks for the review, Lance.

I didn't change order of creation, validation, and movement of the temporary JAR file in order to keep existing behaviour consistent.

A reason to use the main-based testing approach was also the ability to run the test via JEP 330:
`java CreateMissingParentDirectories.java`

That's a good point. Where would we put that information?
- [ ] Extend the descriptions of option `c`/`--create` and/or option `f`/`--file`?
- [ ] As a post scriptum note below the options?
