  -Cargo saves a "dep info" file with a `.d` suffix which is a Makefile-like
  -syntax that indicates all of the file dependencies required to rebuild the
  -artifact. These are intended to be used with external build systems so that
  -they can detect if Cargo needs to be re-executed. The paths in the file are

  +Strips the given path prefix from [dep
  +info](../guide/build-cache.md#dep-info-files) file paths. This config setting

  `"."` would strip all paths starting with the parent directory of the `.cargo`
