prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  ws
   +--__snapshots__
   `--test
       `--__snapshots__
  ```
  
  Convert this description:
  
  _expected is a source directory that maintains 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the structure for you:
  
  At the main level, 'amd' features 1 subdirectories: lib.
  In nested path 'amd > lib', 'lib' has been left empty.
  At the top level, 'cjs' comprises 1 nested folders: lib.
  Within directory hierarchy 'cjs > lib', 'lib' is devoid of content.
  Back to the top level.
  At the top level, 'es' carries 1 directory entries: lib.
  In nested path 'es / lib', The 'lib' repository holds no subdirectories at the moment.
  Back to the top level.
  At the top level, 'system' includes 1 subdirectory elements: lib.
  Within directory hierarchy 'system / lib', 'lib' has nothing inside.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
