Is there a way to set options *programatically* ?

[Emmanuel Charpentier]

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,
