 All these phases are coordinated by the driver. To see the exact sequence, look
 at [the `compile_input` function in `librustc_driver`][compile-input].
-The driver handles all the highest level coordination of compilation - handling
-command-line arguments, maintaining compilation state (primarily in the `Session`),
-and calling the appropriate code to run each phase of compilation. It also handles
-high level coordination of pretty printing and testing. To create a drop-in
-compiler replacement or a compiler replacement, we leave most of compilation
-alone and customise the driver using its APIs.
