Re: [ANN] Export block syntax change

[Ken Mankoff <mankoff@gmail.com>]

Does this new syntax support that oft (or occasionally?) requested LaTeX header export?

I don't think so out of the box, because while LaTeX is a valid export word, LaTeX_preamble is not.

But, can the new syntax be used like this?

    \include{preamble}
    #+BEGIN_EXPORT LaTeX :file preamble.tex
    % preamble commands go here
    #+END_EXPORT

Thanks,

  -k.
