prompt: Your task is to convert the following English description into an ASCII tree format.
  
  lib is a parent directory that bundles 2 subdirectories: A and B.
  At the main level, 'A' contains 1 nested folders: __snapshots__.
  In nested path 'A / __snapshots__', Inside '__snapshots__', you'll find it contains no subdirectories.
  In the root directory, 'B' shelters 1 subdirectory elements: __snapshots__.
  In nested path 'B > __snapshots__', '__snapshots__' hasn't been filled with any content.
  Back to the top level.
  
  
  Format your response in this style:
