Hi, When using #+SETUPFILE and exporting via LaTeX, the LATEX_CLASS_OPTIONS provided in the included file are ignored. With the following two files in the same directory, doing C-c C-e L (org-export to a temporary LaTeX buffer) produces a documentclass with class report (good, as expected) and options [11pt] (not as expected). Placing the LATEX_CLASS_OPTIONS line in top.org produces the expected options. I believe that the reason is that LATEX_CLASS_OPTIONS is not handled within org-infile-export-plist in org-exp.el.
--- top.org --- #+TITLE: LaTeX Class Options #+SETUPFILE: "include.org" * Introduction Here is some text. --- end --- --- include.org --- #+LATEX_CLASS: report #+LATEX_CLASS_OPTIONS: [a4paper,10pt] --- end --- There may be similar keywords for LaTeX or other backends that are also not handled which maybe should be; this one is the one I noticed because I tried to use it. Best wishes, Christophe
