From b904dbade17fa9243edb6b7fb5ea57d52ebeda3b Mon Sep 17 00:00:00 2001 From: Rasmus Date: Wed, 8 Jul 2015 14:44:56 +0200 Subject: [PATCH 2/4] ox-latex: Support TeX variants * org.el (org-latex-default-packages-alist): Only use inputenc and fontenc in pdftex. * ox-latex.el (latex): Add :latex-program. (org-latex-program): New defcustom. (org-latex-programs): New defconst. (org-latex--remove-packages): New function. (org-latex-template): Use new function. (org-latex-pdf-process): Update to use %latex shorthand. (org-latex-compile): Check and use intended compiler. Adds #+latex_program keyword. Note that rubber is dropped from `org-latex-pdf-process' since it does not allow arbitrary latex commands.
