  Emitting Raw Text
  -----------------
  
  When writing documents, it is sometimes required to emit completely unaltered text. Up to this point all
  of the `commands` have decorated the code or text with some formatting, for example a `pre` element. When working 
  with layout or content generation engines such as Jeykll, we sometimes need to emit plain text as declarations to
  said engines. This is where the `raw` command is useful.
