+The `driver` crate is effectively the "main" function for the rust
+compiler. It orchestrates the compilation process and "knits together"
+the code from the other crates within rustc. This crate itself does
+not contain any of the "main logic" of the compiler (though it does
+have some code related to pretty printing or other minor compiler
+options).
+
+For more information about how the driver works, see the [rustc dev guide].
