basic.rs

//! This is a port of `clap_derive`'s [basic.rs example] to use `kommand`.
//!
//! Note the use of `InputByteStream` and `OutputByteStream` instead of
//! `PathBuf` for inputs and outputs. "files" is renamed to "inputs", as the
//! inputs need not actually be files 😊.
//!
//! [basic.rs example]: https://github.com/clap-rs/clap/blob/master/clap_derive/examples/basic.rs

use nameless::{InputByteStream, OutputByteStream};

/// A basic example
///
/// # Arguments
///
/// * `debug`   - Activate debug mode
/// * `verbose` - Verbose mode (-v, -vv, -vvv, etc.)
/// * `speed`   - Set speed
/// * `output`  - Output sink
/// * `nb_cars` - Number of cars
/// * `level`   - admin_level to consider
/// * `inputs`  - inputs to process
