//! clap setup.
//!
//! clap is a crate for command line argument parsing.
//! See https://docs.rs/clap/
//!
//! We prefer clap using the `command!` macro, which runs at compile time.
//! We prefer clap using the builder pattern, which offers more capabilties.
//!
//! We favor our convention of doing clap setup in a file named `clap.rs`,
//! rather than in `main.rs`, because we favor the separation of concerns.
