Usage

Usage is a spec and CLI for defining CLI tools. Arguments, flags, environment variables, and config files can all be defined in a Usage spec. It can be thought of like OpenAPI (swagger) for CLIs. Here are some potential reasons for defining your CLI with a Usage spec:

• Generate autocompletion scripts
• Generate markdown documentation
• Generate man pages
• Use an advanced arg parser in any language
• Scaffold one spec into different CLI frameworks—even different languages
• [coming soon] Host your CLI documentation on usage.sh
