// 1) build an example: cargo build --example simple_enum
// 2) go to the `examples` folder: cd target/debug/examples
// 3) run an example: ./simple_enum (without parameters) => entered interactive mode
//                    ./simple_enum network              => mode: Ok(Network)
//                    ./simple_enum offline              => mode: Ok(Offline)
// To learn more about the parameters, use "help" flag: ./simple_enum --help
