prompt: Your task is to convert the following English description into an ASCII tree format.
  
  _expected is a head directory that includes 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the construction for you:
  
  At the main level, 'amd' includes 1 subdirectory elements: rollup_virtual.
  Within directory hierarchy 'amd > rollup_virtual', 'rollup_virtual' contains nothing at present.
  Back to the top level.
  At the main level, 'cjs' contains 1 folders: rollup_virtual.
  Within directory hierarchy 'cjs → rollup_virtual', The 'rollup_virtual' storage space sits empty.
  At the top level, 'es' encapsulates 1 subfolders: rollup_virtual.
  Within directory hierarchy 'es / rollup_virtual', The 'rollup_virtual' collection holds no subdirectories at the moment.
  Back to the top level.
  At the main level, 'system' groups 1 directory entries: rollup_virtual.
  At level 2, in directory path 'system > rollup_virtual', The 'rollup_virtual' collection hasn't been filled with any content.
  
  
  Format your response in this style:
  ```
  autojump
   +--bin
   +--docs
   +--tests
   |   +--integration
   |   `--unit
   `--tools
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
