## What it is
Fang is a Go library that wraps Cobra CLI applications with batteries-included styling and features. It provides styled help and error output, automatic version flags, shell completions, and manpage generation with minimal setup.

## Use cases
- add styled help output to my cobra cli
- generate shell completions for a go command-line tool
- auto-generate manpages for my cli app
- add a --version flag to my go cli
- make cli error messages look nicer
- theme my command-line tool's help pages

## When to avoid
- you don't use Cobra for your CLI
- you need fine-grained control over help rendering or a non-Cobra framework

## Facets
- artifact type: library
- maturity: experimental
- function: cli, developer-tools, templating, documentation
- domain: developer-tools
- platform: go, cross-platform, cli
- tags: cobra, shell-completions, manpages, theming, cli-styling, command-line
