prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  autojump
   +--bin
   +--docs
   +--tests
   |   +--integration
   |   `--unit
   `--tools
  ```
  
  Convert this description:
  
  vendor is a top-level directory that contains 4 subdirectories. Notable ones include backbone, firebug-lite, json-js among others.
  
  Let me break down the composition for you:
  
  At the top level, 'backbone' maintains 1 child directories: test.
  In nested path 'backbone > test', 'test' houses 1 folders for testing purposes.
  At level 3, in directory path 'backbone / test / setup', The 'setup' section has no content.
  At the main level, 'firebug-lite' encompasses 2 directories: skin, src.
  At level 2, in directory path 'firebug-lite / skin', 'skin' retains 1 contained folders: xp.
  At level 3, in directory path 'firebug-lite → skin → xp', 'xp' is an empty container.
  In nested path 'firebug-lite > src', The 'src' directory contains nothing at present.
  Back to the top level.
  In the root directory, 'json-js' is unpopulated.
  At the main level, 'underscore' features 1 nested folders: test.
  In nested path 'underscore / test', Inside 'test', you'll find it is a vacant space.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
