  At the main level, 'in-files' bundles 1 subdirectories: src.
  Within directory hierarchy 'in-files → src', The 'src' container has been left empty.
  At the top level, 'out-files' carries 1 subfolders: lib.
  At level 2, in directory path 'out-files > lib', 'lib' holds no subdirectories at the moment.

   |       `--api
   `--test
  ```
