> Apache commons-cli has served us well for years, but our CLI has out-grown
> its capabilities, with multiple sub commands and a plethora of options and
> arguments. We have much custom code to work around limitations.
> By embracing [Picocli|https://picocli.info/], an annotation based cli
> framework, it will be easier to maintain the cli and add further tools. We
> propose to target 10.0 and do work gradually in a feature branch.
