   |   |   `--__tests__
   |   |       `--ncp
   |   |           `--fixtures
   |   |               +--modified-files
   |   |               |   +--out
   |   |               |   `--src
   |   |               `--regular-fixtures
  ```
  
  Convert this description:
  
  src is a base directory that incorporates 2 subdirectories: main and test.
  At the main level, 'main' bundles 1 directories: groovy.
  At level 2, in directory path 'main / groovy', 'groovy' remains unused.
  Back to the top level.
  At the main level, 'test' houses 1 test-related directories.
  In nested path 'test / groovy', 'groovy' is unpopulated.
  Back to the top level.
