  dir --out-dir --watch with external dependencies is a principal directory that groups 2 subdirectories: in-files and out-files.
  In the root directory, 'in-files' contains 1 subdirectories: src.
  In nested path 'in-files / src', 'src' holds no subdirectories at the moment.
  Back to the top level.
  At the top level, 'out-files' hosts 1 subdirectories: lib.
  At level 2, in directory path 'out-files / lib', 'lib' is a vacant space.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
