prompt: Your task is to convert the following English description into an ASCII tree format.
  
  kotlin is a principal directory that bundles 2 subdirectories: app and buildSrc.
  At the main level, 'app' is unpopulated.
  At the main level, 'buildSrc' hosts 1 contained folders: src.
  At level 2, in directory path 'buildSrc → src', Within 'src', you'll find 1 subdirectory elements for code structure.
  At level 3, in directory path 'buildSrc > src > main', 'main' possesses 1 subdirectory elements: kotlin.
  At level 4, in directory path 'buildSrc > src > main > kotlin', Inside 'kotlin', you'll find it stands empty.
  
  
  Format your response in this style:
  ```

   +--config
   |   +--src

   |       +--fixtures
   |       |   +--has-env-in-key
   |       |   +--has-number-setting
   |       |   +--never-built-dependencies

   |       |   +--pkg-with-valid-workspace-yaml
   |       |   `--settings-in-workspace-yaml
  ```
