prompt: Your task is to convert the following English description into an ASCII tree format.
  
  cli is a principal directory that maintains 2 subdirectories: foo and ignore-pattern-relative.
  At the top level, The 'foo' container is barren.
  At the main level, 'ignore-pattern-relative' maintains 1 subdirectory elements: subdir.
  In nested path 'ignore-pattern-relative → subdir', 'subdir' holds 1 directory entries: subsubdir.
  At level 3, in directory path 'ignore-pattern-relative / subdir / subsubdir', Inside 'subsubdir', you'll find it has nothing inside.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  gradle
   +--api
   +--internal
   `--util
       `--internal
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
