4 months ago I'm going to close this now. After some investigation, the generated code by argc is not posix-sh compliant and the project is not very focused on generating posix-sh compliant code and instead focused on having argc available to do the argument handling. This is a reasonable choice from my perspective, but makes it a bad fit for this project.

It's mainly marketed as a way to avoid boilerplate in scripts, but it also has a "build" option which can generate the boilerplate CLI code. I want to see if we can use this because then the CLI, the help messages, and the man pages would all be generated from the same source of truth.
