prompt: Your task is to convert the following English description into an ASCII tree format.
  
  server is a head directory that consolidates 6 subdirectories. Notable ones include api, exec, expiry among others.
  
  Let me break down the formation for you:
  
  At the main level, The 'api' container stands empty.
  At the main level, The 'exec' collection holds no subdirectories at the moment.
  In the root directory, Inside 'expiry', you'll find it remains unused.
  At the main level, 'health' incorporates 1 folders: gc.
  In nested path 'health → gc', Inside 'gc', you'll find it is a vacant space.
  In the root directory, Inside 'scaninfo', you'll find it contains nothing at present.
  In the root directory, 'stats' has been left empty.
  
  
  Format your response in this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
