class_docstr: Converts a token stream to text.
  
  Options accepted:
  
  ``style``
      The style to use, can be a string or a Style subclass
      (default: "default"). Not used by e.g. the
      TerminalFormatter.
  ``full``
      Tells the formatter to output a "full" document, i.e.
      a complete self-contained document. This doesn't have
      any effect for some formatters (default: false).
  ``title``
      If ``full`` is true, the title that should be used to
      caption the document (default: '').
  ``encoding``
      If given, must be an encoding name. This will be used to
      convert the Unicode token strings to byte strings in the
      output. If it is "" or None, Unicode strings will be written
      to the output file, which most file-like objects do not
      support (default: None).
  ``outencoding``
      Overrides ``encoding`` if given.
docstr: Format ``tokensource``, an iterable of ``(tokentype, tokenstring)``
  tuples and write it into ``outfile``.
