      """
      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``).
