Echo JS 0.11.0

Alternatively use the built-in: util.parseArgs

I know :-)
It's stable starting from Node.js 20, but I need to support Node.js 10+.

Wow, just out of curiosity why can't your users upgrade?

Nice, though I'm not sure why I would choose this over yargs or another similar, existing library.
