prompt: Your task is to convert the following English description into an ASCII tree format.
  
  librec is a base directory that collects 2 subdirectories: __snapshots__ and lib.
  At the main level, The '__snapshots__' directory has nothing inside.
  In the root directory, 'lib' has 2 subdirectories that organize the source code.
  At level 2, in directory path 'lib / A', 'A' keeps 1 folders: __snapshots__.
  In nested path 'lib → A → __snapshots__', The '__snapshots__' directory hasn't been filled with any content.
  Within directory hierarchy 'lib > B', 'B' comprises 1 contained folders: __snapshots__.
  At level 3, in directory path 'lib → B → __snapshots__', '__snapshots__' is devoid of content.
  Back to the top level.
