    await Parser.Default.ParseArguments<Options>(args)
                .MapResult(
                    async options => await RunAndReturnExitCodeAsync(options),
                    _ => Task.FromResult(1));

In case of missing or unknown argument or parsing error, the errors are displayed with the usage explanation message and the application exits.
