* - Currently, when pulling this crate in as a dependency I am not able to
  create a recording because it looks for the recordings under
  ~/.cargo.../testcmds/recording-name.json. Instead, we should use the
  runtime CARGO_MANIFEST_DIR, which will point to the crate where
  commandeer is being imported.
