Macro clap::crate_license

macro_rules! crate_license {
    () => { ... };
}

Allows you to pull the licence from your Cargo.toml at compile time. If the license field is empty, then the licence-field is read. If both fields are empty, then an empty string is returned.

Examples

let m = App::new("app")
            .license(crate_license!())
            .get_matches();
