//! The shortest end-to-end use of pretty_lang: build one document, render it at
//! two widths, and watch it reflow.
//!
//! Run with:
//!
//! ```text
//! cargo run --example quick_start
//! ```

use pretty_lang::Doc;

    // A function call whose arguments should sit on one line when they fit and
    // stack one-per-line, indented, when they do not.
