I need to include 'amsmath' package in my LaTeX export. Using #+LATEX_HEADER: \usepackage{xyz} adds it at the end of the list, and then there are LaTeX related problems.
I tried to find where the default list is defined - it seems like it is in org.el. However, I have several copies of this file, and I don't know which one is the right one to change. So, two questions: 1. Should I change the org.el or is it somewhere else? 2. If it is the org.el, then how can I tell which file is the one which is used? Should I restart emacs after each edit of this file for the changes to take effect? Thanks! Dror Atariah
