Dear list, I'd like to create a function able to set some options, namely - `#+options: tex:`{t|dvipng|imagemagick} - `#+export-file-name:` I have been unable to find a *documented* way to do that from `elacs-lisp`. I *think* that an `org` source block could place those options in the buffer, but I can't find a way to reliably trigger a "setup refreshment" of these options from `emacs-lisp`. Any ideas ? Sincerely yours, -- Emmanuel Charpentier
