prompt: Your task is to convert the following English description into an ASCII tree format.
  
  configurations is a head directory that gathers 4 subdirectories. Notable ones include cwd, empty, parser among others.
  
  Let me break down the layout for you:
  
  In the root directory, 'cwd' holds no subdirectories at the moment.
  At the main level, 'empty' is a vacant space.
  At the main level, Inside 'parser', you'll find it has been left empty.
  At the main level, 'single-quotes' encompasses 1 nested folders: subdir.
  In nested path 'single-quotes > subdir', Inside 'subdir', you'll find it is devoid of content.
  
  
  Format your response in this style:
  ```
