-//! Minimal, flexible command-line parser
-//!
-//! As opposed to a declarative parser, this processes arguments as a stream of tokens.  As lexing
-//! a command-line is not context-free, we rely on the caller to decide how to interpret the
-//! arguments.
-//!
-//! # Examples
-//!
-//! ```rust
-//! use std::path::PathBuf;
-//! use std::ffi::OsStr;
-//!
-//! type BoxedError = Box<dyn std::error::Error + Send + Sync>;
-//!
-//! #[derive(Debug)]
-//! struct Args {
-//!     paths: Vec<PathBuf>,
-//!     color: Color,
-//!     verbosity: usize,
-//! }
-//!
-//! #[derive(Debug)]
-//! enum Color {
-//!     Always,
-//!     Auto,
-//!     Never,
-//! }
-//!
-//! impl Color {
-//!     fn parse(s: Option<&OsStr>) -> Result<Self, BoxedError> {
-//!         let s = s.map(|s| s.to_str().ok_or(s));
-//!         match s {
-//!             Some(Ok("always")) | Some(Ok("")) | None => {
-//!                 Ok(Color::Always)
-//!             }
-//!             Some(Ok("auto")) => {
-//!                 Ok(Color::Auto)
-//!             }
-//!             Some(Ok("never")) => {
-//!                 Ok(Color::Never)
-//!             }
-//!             Some(invalid) => {
-//!                 Err(format!("Invalid value for `--color`, {invalid:?}").into())
