cli.rs

//! The `stuffr` command's argument surface.
//!
//! Pulled out of `main.rs` and re-exported from `lib.rs` so an integration
//! test can ask clap itself — via [`clap::CommandFactory`] — what flags and
//! subcommands exist, rather than keeping a second, hand-maintained list that
//! the examples page could silently drift out of sync with. `main.rs` still
//! owns everything that isn't the argument shape: parsing, dispatch, and the
//! examples text itself.
