+When beets imports all the files in a directory, it tries to remove the
+directory if it's empty. A directory is considered empty if it only contains
+files whose names match the glob patterns in `clutter`, which should be a list
+of strings. The default list consists of "Thumbs.DB" and ".DS_Store".
