prompt: Your task is to convert the following English description into an ASCII tree format.
  
  variable-layout is a fundamental directory that incorporates 3 subdirectories: __mocks__, __tests__ and src.
  In the root directory, '__mocks__' is blank.
  At the top level, '__tests__' houses 1 folders for testing purposes.
  At level 2, in directory path '__tests__ > __snapshots__', The '__snapshots__' data structure is blank.
  Back to the top level.
  At the top level, The 'src' section encapsulates 2 folders for code organization.
  In nested path 'src → chains', 'chains' is blank.
  Within directory hierarchy 'src > scopes', The 'scopes' collection contains no subdirectories.
  
  
  Format your response in this style:
  ```
  go-winio
   +--internal
   |   +--fs
   |   +--socket
   |   `--stringbuffer
   `--pkg
       `--guid
  ```
  
  Provide your answer wrapped in <ascii_formatted> tags.
