Re: CLI parsing—with `--help` text—`--foo bar`, how to give additional parameters to `bar`?

Hi Sam,
I’ve been using abseil python API.

https://abseil.io/docs/python/guides/flags <https://abseil.io/docs/python/guides/flags>
https://abseil.io/docs/python/quickstart <https://abseil.io/docs/python/quickstart>

It’s a distributed command line system with features that appear to support your needs.
