Which packages do you recommend for building cli tools?
https://github.com/jessevdk/go-flags provides a pretty neat way to specify flags and handle commands. Not so much extensible as cobra, but good enough for small cli tools

Show HN: New set of Go libraries for CLI Development
flags aims to merge the concepts from https://github.com/jessevdk/go-flags, and https://github.com/octago/sflags, both relying on struct tags to define CLI command specs. The flags library uses these underlying concepts to produce complete `cobra.Command` trees, and brings many comfort-of-life improvements for the generated applications/commands.

Eclipse: python-fire inspired library to simplify creating CLIs in Go, on top of Cobra
