   `--simplify-non-boolean
  ```
  
  Convert this description:
  
  src is a parent directory that incorporates 3 subdirectories: dagre-layout, dagre-lib and layout.
  At the main level, 'dagre-layout' keeps 1 subdirectories: rank.
  In nested path 'dagre-layout > rank', 'rank' appears to be unused.
  Back to the top level.
  In the root directory, 'dagre-lib' features 4 diverse directories.
  At level 2, in directory path 'dagre-lib > data', 'data' is empty.
  Within directory hierarchy 'dagre-lib / order', The 'order' data structure contains nothing at present.
  In nested path 'dagre-lib / position', 'position' remains unused.
  At level 2, in directory path 'dagre-lib → rank', The 'rank' compartment holds no subdirectories at the moment.
  At the top level, 'layout' is barren.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
