argparse

Handles positional arguments, options, flags, and subcommands with features like repeatable options and count modifiers, as shown in the example with `-I` include locations.

Generates detailed usage and help messages automatically based on argument definitions, reducing boilerplate and ensuring consistent CLI interfaces, demonstrated in the help output for the example script.

Provides clear error feedback with suggestions for typos, such as 'Did you mean '--output'?', enhancing user experience during command-line input errors.

Supports short and long option formats, default values, and structured output tables, making it easy to integrate complex argument parsing into Lua scripts with minimal code.
