	//! The [`Args`] struct contains the top level options. The [`Action`] enum contains the top
	//! level subcommands. Beyond that, `*Args` structs contain options for that level, and
	//! `*Action` enums contain subcommands below that level. In structs, field names are
	//! generally transformed to options using by being kebab-cased.
	//!
	//! For example, [`caddy::configure_tamanu::ConfigureTamanuArgs`] represents the subcommand:
	//!
	//! ```text
	//! $ bestool caddy configure-tamanu
	//! ```

	//!     pub email: Option<String>,
