prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  contrib
   +--admin
   |   `--_images
   +--gis
   |   `--install
   `--postgres
  ```
  
  Convert this description:
  
  rewriter is a head directory that maintains 4 subdirectories. Notable ones include __snapshots__, lib, script among others.
  
  The project source code seems to be organized in the 'lib' section.
  
  Let me break down the framework for you:
  
  At the main level, '__snapshots__' is barren.
  At the main level, The 'lib' collection includes 2 folders for code organization.
  In nested path 'lib → threads', 'threads' is a vacant space.
  At level 2, in directory path 'lib → util', Inside 'util', you'll find it lacks any subdirectories.
  In the root directory, The 'script' compartment is empty.
  At the top level, 'test' hosts 2 test-related directories.
  At level 2, in directory path 'test / fixtures', Inside 'fixtures', you'll find it is an empty container.
  In nested path 'test > unit', 'unit' holds no subdirectories at the moment.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
