1The `driver` crate is effectively the "main" function for the rust2compiler. It orchestrates the compilation process and "knits together"3the code from the other crates within rustc. This crate itself does4not contain any of the "main logic" of the compiler (though it does5have some code related to pretty printing or other minor compiler6options).78For more information about how the driver works, see the [rustc dev guide].910[rustc dev guide]: https://rustc-dev-guide.rust-lang.org/rustc-driver/intro.html
