prompt: Your task is to convert the following English description into an ASCII tree format.
  
  filename --out-dir --relative is a root directory that gathers 2 subdirectories: in-files and out-files.
  At the top level, 'in-files' incorporates 1 subdirectories: src.
  In nested path 'in-files → src', The 'src' data structure holds no subdirectories at the moment.
  Back to the top level.
  At the top level, 'out-files' maintains 1 nested folders: lib.
  In nested path 'out-files → lib', 'lib' hasn't been filled with any content.
  
  
  Format your response in this style:
  ```
