prompt: Your task is to convert the following English description into an ASCII tree format.
  
  dir-sourcemap-config-true is a principal directory that holds 2 subdirectories: in-files and out-files.
  At the top level, 'in-files' keeps 1 folders: src.
  Within directory hierarchy 'in-files > src', Within 'src', you'll find 1 contained folders for code structure.
  Within directory hierarchy 'in-files → src → bar', Inside 'bar', you'll find it hasn't been filled with any content.
  At the top level, 'out-files' encapsulates 1 folders: lib.
  At level 2, in directory path 'out-files / lib', Within 'lib', you'll find 1 directory entries for code structure.
  In nested path 'out-files → lib → bar', 'bar' is vacant.
  
  
  Format your response in this style:
  ```
