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:
  
  src is a principal directory that holds 3 subdirectories: __test__, components and docs.
  At the main level, '__test__' houses 1 folders for testing purposes.
  In nested path '__test__ > composeStories', 'composeStories' shelters 1 child directories: __snapshots__.
  At level 3, in directory path '__test__ / composeStories / __snapshots__', '__snapshots__' is empty.
  Back to the top level.
  In the root directory, Inside 'components', you'll find it holds no subdirectories at the moment.
  In the root directory, 'docs' hosts 1 folders: sample.
  In nested path 'docs / sample', 'sample' holds no subdirectories at the moment.
