prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  export-default
   +--__snapshots__
   +--escaped
   |   `--__snapshots__
   `--export-default-from
       `--__snapshots__
  ```
  
  Convert this description:
  
  pre-compiled-headers is a principal directory that includes 2 subdirectories: groovy and tests.
  At the main level, 'groovy' features 1 nested folders: src.
  In nested path 'groovy > src', 'src' contains 2 subdirectories that organize the source code.
  At level 3, in directory path 'groovy / src / hello', 'hello' keeps 2 subdirectories: cpp, headers.
  Within directory hierarchy 'groovy > src > hello > cpp', Inside 'cpp', you'll find it has no content.
  At level 4, in directory path 'groovy / src / hello / headers', Inside 'headers', you'll find it stands empty.
  In nested path 'groovy → src → main', 'main' stores 1 child directories: cpp.
  At level 4, in directory path 'groovy / src / main / cpp', 'cpp' is vacant.
  At the top level, The 'tests' storage space is blank.
