Rust Version

1.48.0

Clap Version

2.33.3

Minimal reproducible code

Using rust edition 2018:

fn main() {
    let yaml = clap::load_yaml!("cli.yml");
    let matches = App::from_yaml(yaml).get_matches();
}

cli.yaml:

version: "1.0"
author: Tester <[email protected]>
about: parse command line parameters
args:
    - config:
        short: c
        long: config
        value_name: FILE
        help: Sets a custom config file
        takes_value: true

side note: why can I not make this window bigger (using Firefox)!! Very annoying :-(

Steps to reproduce the bug with the above code

cargo run -- --help

Actual Behaviour

Only the built-in help from clap is shown with the only parameters -h & -V

Expected Behaviour

Expect everything to work with the name of the of the program simply the one from Cargo.toml: package.name

Additional Context

No response

Debug Output

No response
