prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```

   |   +--compat
   |   |   `--config
   |   +--source-maps

  ```
  
  Convert this description:
  
  _expected is a principal directory that groups 4 subdirectories. Notable ones include amd, cjs, es among others.
  
  Let me break down the construction for you:
  
  At the main level, 'amd' features 2 nested folders: assets, nested.
  Within directory hierarchy 'amd / assets', 'assets' stands empty.
  In nested path 'amd > nested', Inside 'nested', you'll find it is barren.
  In the root directory, 'cjs' carries 2 folders: assets, nested.
  At level 2, in directory path 'cjs > assets', Inside 'assets', you'll find it lacks any subdirectories.
  At level 2, in directory path 'cjs / nested', 'nested' is blank.
  At the top level, 'es' hosts 2 subfolders: assets, nested.
  At level 2, in directory path 'es > assets', The 'assets' storage space is unpopulated.
  Within directory hierarchy 'es > nested', 'nested' is empty.
  At the top level, 'system' encapsulates 2 folders: assets, nested.
  Within directory hierarchy 'system > assets', 'assets' is unpopulated.
  Within directory hierarchy 'system > nested', Inside 'nested', you'll find it is an empty container.
  Back to the top level.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
