How can I have org #+INCLUDE: ignore configurations from the included files? I'm thinking of cases where I don't want Latex Classes to be messed up. For example, if I have two org files book.org and chapter.org that look like the following:
#+LATEX_CLASS: book * Chapter 1 #+INCLUDE: chapter.org
#+LATEX_CLASS: report * Results
Then on export (to another Org file) I get the following:
#+LATEX_CLASS: book * Chapter 1 #+LATEX_CLASS: report ** Results
This is not good because a latex-export may get messed up (the last latex_class takes precedence, so I would end up with a report and not a book). What is the recommended way to avoid these issues?
