  Convert this description:
  
  librec is a head directory that assembles 2 subdirectories: __snapshots__ and lib.
  At the main level, Inside '__snapshots__', you'll find it has nothing inside.
  In the root directory, 'lib' organizes 2 subdirectories that organize the source code.
  At level 2, in directory path 'lib > A', 'A' groups 1 nested folders: __snapshots__.
  Within directory hierarchy 'lib > A > __snapshots__', '__snapshots__' is currently empty.
  In nested path 'lib / B', 'B' groups 1 subdirectory elements: __snapshots__.
  Within directory hierarchy 'lib → B → __snapshots__', Inside '__snapshots__', you'll find it is barren.
  Back to the top level.
