class_docstr: Format tokens with BBcodes. These formatting codes are used by many
  bulletin boards, so you can highlight your sourcecode with pygments before
  posting it there.
  
  This formatter has no support for background colors and borders, as there
  are no common BBcode tags for that.
  
  Some board systems (e.g. phpBB) don't support colors in their [code] tag,
  so you can't use the highlighting together with that tag.
  Text in a [code] tag usually is shown with a monospace font (which this
  formatter can do with the ``monofont`` option) and no spaces (which you
  need for indentation) are removed.
  
  Additional options accepted:
  
  `style`
      The style to use, can be a string or a Style subclass (default:
      ``'default'``).
  
  `codetag`
      If set to true, put the output into ``[code]`` tags (default:
      ``false``)
  
  `monofont`
      If set to true, add a tag to show the code with a monospace font
      (default: ``false``).
