+The `path.relative()` method returns the relative path from `from` to `to` based
+on the current working directory. If `from` and `to` each resolve to the same
+path (after calling `path.resolve()` on each), a zero-length string is returned.
 
 If a zero-length string is passed as `from` or `to`, the current working
 directory will be used instead of the zero-length strings.
