  Convert this description:
  
  c is a base directory that maintains 2 subdirectories: groovy and tests.
  At the main level, 'groovy' shelters 1 subdirectory elements: src.
  At level 2, in directory path 'groovy → src', 'src' stores 2 subdirectories that organize the source code.
  In nested path 'groovy > src > hello', 'hello' keeps 2 directories: c, headers.
  In nested path 'groovy > src > hello > c', 'c' has no content.
  Within directory hierarchy 'groovy / src / hello / headers', 'headers' remains unused.
  Within directory hierarchy 'groovy → src → main', 'main' holds 1 nested folders: c.
  At level 4, in directory path 'groovy → src → main → c', The 'c' storage space contains nothing at present.
  Back to the top level.
  In the root directory, The 'tests' collection holds no subdirectories at the moment.
