prompt: Your task is to convert an English description into an ASCII tree format using this style:
  ```
  go-winio
   +--internal
   |   +--fs
   |   +--socket
   |   `--stringbuffer
   `--pkg
       `--guid
  ```
  
  Convert this description:
  
  src is a root directory that organizes 2 subdirectories: hello and main.
  At the top level, 'hello' maintains 2 directory entries: cpp, headers.
  At level 2, in directory path 'hello → cpp', Inside 'cpp', you'll find it is an empty container.
  In nested path 'hello > headers', Inside 'headers', you'll find it appears to be unused.
  Back to the top level.
  In the root directory, 'main' houses 1 directories: cpp.
  In nested path 'main → cpp', The 'cpp' data structure has no content.
  
  
  Provide your answer wrapped in <ascii_formatted> tags.
