## Label which directory is which in the comment
Lastly, I needed clarification about which directory was renamed in the example. Without prior knowledge, it could be that a directory named "bardir" is being renamed to the current dir or that the current dir is being inserted as a "bardir." The input args are `path` and `src_path`, which provides a little clue.
To make the example more explicit, I added that information to the comment.
