 That allows you to specify the additional syntax of the `--extern` flag, such as
 renaming a dependency. For example, `//@ aux-crate:foo=bar.rs` will compile
 `auxiliary/bar.rs` and make it available under then name `foo` within the test.
-This is similar to how Cargo does dependency renaming.

 `aux-bin` is similar to `aux-build` but will build a binary instead of a
 library. The binary will be available in `auxiliary/bin` relative to the working
