I have a Ruby block that creates some dot code.  I'd like to be able to have the #+RESULTS block enclosed
in a src block that starts "#+BEGIN_SRC dot".  Using :results value code generates the enclosing SRC block,
but using the same language (Ruby) used to generate the code.  Is there a way to specify the coding language
of a generated #+RESULTS  src block?  

Thanks,

Greg
