To follow up on this because it seemed a bit simper..., I added the
example to my file:

#+LaTeX_HEADER: \usepackage{framed}
#+LaTeX_HEADER: \usepackage{xcolor}
#+LaTeX_HEADER: \definecolor{shadecolor}{gray}{.95}
#+LaTeX_HEADER: \newenvironment{results}{\begin{shaded}}{\end{shaded}}

But it doesn't change anything. Since it says this will affect a
"results block," I [intuitively] tried:

#+begin_results
test
#+end_results

But don't see anything different. Did I mis-interpret how this works?
Or do I need the above /with/ either minted or listing and it's not
standalone?


Thanks,
John
