/// If you are using Rust 2018 no `external crate byteorder;` is necessary
// The `gen` module exists because `cargo test` fails
// if `j1939.rs` is directly in the examples folder
// (since it's treated like an example and a `main` is expected).
// Usually you could directly use `mod j1939;` here.
