prompt: Your task is to convert the following English description into an ASCII tree format.
  
  libflow-typed is a source directory that gathers 2 subdirectories: __snapshots__ and flow-typed.
  At the top level, '__snapshots__' has yet to be populated.
  At the main level, 'flow-typed' bundles 1 folders: __snapshots__.
  In nested path 'flow-typed → __snapshots__', The '__snapshots__' storage space contains nothing at present.
  
  
  Format your response in this style:
  ```

       `--matching
  ```
