prompt: Your task is to convert the following English description into an ASCII tree format.
  
  tools is a origin directory that groups 5 subdirectories. Notable ones include docgen, doctest, eslint among others.
  
  Let me break down the architecture for you:
  
  At the top level, 'docgen' groups 1 subdirectories: src.
  In nested path 'docgen / src', 'src' contains nothing at present.
  At the main level, 'doctest' retains 1 test-related directories.
  At level 2, in directory path 'doctest > src', Inside 'src', you'll find it stands empty.
  Back to the top level.
  In the root directory, 'eslint' carries 1 subdirectory elements: src.
  At level 2, in directory path 'eslint / src', 'src' lacks any subdirectories.
  Back to the top level.
  At the top level, 'mocha-runner' hosts 1 nested folders: src.
  Within directory hierarchy 'mocha-runner / src', Inside 'src', you'll find it is vacant.
  In the root directory, The 'third_party' container is unpopulated.
  
  
  Format your response in this style:
  ```
  node-fs-extra
   +--docs
   +--lib
   |   +--__tests__
   |   +--copy
   |   |   `--__tests__
   |   |       `--ncp
   |   |           `--fixtures
   |   |               +--modified-files
   |   |               |   +--out
   |   |               |   `--src
   |   |               `--regular-fixtures
  ```
