The code below is working fine as long as I stay in `org-mode`. But it shows
its limitations when I do `M-x org-publish-all`, at which time, instead of
having the text with style verbatim, I get the text within backticks.
Is there any improvement you could think of that would fix that?
Thanks,
Chris
