//! Using `narrate::Result` when returning from `main` will use
//! `narrate::Error`'s `Debug` formatting. It looks similar to
//! `narrate::report::err_full` output, except it doesn't use any colors.
//!
//! This example will print:
//! ```console
//! Error: outer error
//! Cause: inner error
//!
//! help message
//! ```
