prompt: Your task is to convert the following English description into an ASCII tree format.
  
  useAntType is a core directory that maintains 3 subdirectories: groovy, kotlin and tests.
  At the top level, 'groovy' encapsulates 1 child directories: libs.
  At level 2, in directory path 'groovy → libs', The 'libs' collection hasn't been filled with any content.
  Back to the top level.
  At the top level, 'kotlin' maintains 1 contained folders: libs.
  Within directory hierarchy 'kotlin / libs', Inside 'libs', you'll find it is unpopulated.
  In the root directory, 'tests' is devoid of content.
  
  
  Format your response in this style:
  ```
  node-fs-extra
   +--docs
   +--lib
   |   +--__tests__
   |   +--copy
   |   |   `--__tests__
   |   |       `--ncp
   |   |           `--fixtures
   |   |               +--modified-files
   |   |               |   +--out
   |   |               |   `--src
   |   |               `--regular-fixtures
  ```
