A minimal package for building CLIs in Go, built around spf13/pflag with inspiration from existing CLI packages.
- Add validation for redeclared flag names (and shorthand) in subcommands (instead of pflag panic).
- Print global flags in a separate section under usage.
- Generate more flag types :D
- Validate arguments based on Usage? E.g.
command <in> <out>could validate that two positional arguments exist during parse?
