prompt: Your task is to convert the following English description into an ASCII tree format.
  
  fixtures is a primary directory that groups 4 subdirectories. Notable ones include basic, empty, nested-workspaces among others.
  
  Let me break down the system for you:
  
  At the top level, 'basic' retains 1 child directories: @packages.
  In nested path 'basic → @packages', '@packages' is a scoped package with 2 components.
  At level 3, in directory path 'basic → @packages → a', The 'a' directory has been left empty.
  Within directory hierarchy 'basic / @packages / b', The 'b' collection is devoid of content.
  Back to the top level.
  In the root directory, The 'empty' section lacks any subdirectories.
  At the main level, 'nested-workspaces' contains 1 subfolders: @packages.
  At level 2, in directory path 'nested-workspaces / @packages', '@packages' is a scoped package with 2 components.
  At level 3, in directory path 'nested-workspaces > @packages > a', 'a' encompasses 1 subfolders: nested-a.
  Within directory hierarchy 'nested-workspaces / @packages / a / nested-a', 'nested-a' is vacant.
  In nested path 'nested-workspaces → @packages → b', 'b' carries 1 nested folders: nested-b.
  At level 4, in directory path 'nested-workspaces → @packages → b → nested-b', 'nested-b' is blank.
  In the root directory, 'scoped' bundles 1 subdirectory elements: @packages.
  At level 2, in directory path 'scoped / @packages', '@packages' is a scoped package with 2 components.
  At level 3, in directory path 'scoped / @packages / a', 'a' is unpopulated.
  In nested path 'scoped → @packages → b', 'b' hasn't been filled with any content.
  Back to the top level.
  
  
  Format your response in this style:
  ```
  packages
   +--pkg-a
   |   `--src
   +--pkg-b
   |   `--src
   `--shared
       `--src
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
