Got it... I think :) Perhaps the Worg page should clarify this, as it
does, then, seem like #+include is the best practice for LaTeX options
and #+setupfile is just supposed to be for TODO settings? I say this
as my googling for "Org keywords org-mode" yields this:
- http://orgmode.org/manual/Per_002dfile-keywords.html

Is that the meaning of "Org keywords" (just TODO keyword/work flow
settings)? Or would you also include #+options in that group?

Good to know. I was unaware of that. Is there a list of these? The
only one I've run across is the new Beamer export Worg page:
- http://orgmode.org/worg/exporters/beamer/ox-beamer.html#config

That's a great table and it would be great to have that for all
properties. Or perhaps this page could link to that comprehensive list
if it exists, or let the user know how to find it:
- http://orgmode.org/manual/Special-properties.html#Special-properties

I'll consider that. My setups aren't typically so complicated to
probably require something like this. Out of curiosity, would
#+include in the header of the file be overridden by #+include in the
subtree? If not, it could be as simple as having a temporary include
file that I'd modify prior to subtree export and then just comment out
the main buffer #+include prior to exporting.

Thanks again for the clarification. I do hope I can repay those doing
work on actual code (where I lack the abilities) by getting some of
these gems out of the mailing list and into Worg for the community.


Best regards,
John
