;;; Commentary:
;;
;; This elisp code integrates Static MathJax into the
;; HTML export process of Org-mode.
;;
;; The supporting files for this package are in contrib/scripts/staticmathjax
;; Please read the README.org file in that directory for more information.

;; To use it, evaluate it on startup, add the following to your .emacs:

;; (require 'org-static-mathjax)
;;
;; You will then have to customize the following two variables:
;; - org-static-mathjax-app-ini-path
;; - org-static-mathjax-local-mathjax-path
;;
;; If xulrunner is not in your $PATH, you will also need to customize
;; org-static-mathjax-xulrunner-path.
;;
;; If everything is setup correctly, you can trigger Static MathJax on
;; export to HTML by adding the following line to your Org file:
;; #+StaticMathJax: embed-fonts:nil output-file-name:"embedded-math.html"
;;
;; You can omit either argument.
;; embed-fonts defaults to nil. If you do not specify output-file-name,
;; the exported file is overwritten with the static version.
;;
;; If embed-fonts is non-nil, the fonts are embedded directly into the
;; output file using data: URIs.
;;
;; output-file-name specifies the file name of the static version. You
;; can use any arbitrary lisp form here, for example:
;; output-file-name:(concat (file-name-sans-extension buffer-file-name) "-static.html")
;;
;; The StaticMathJax XULRunner application expects a UTF-8 encoded
;; input file. If the static version displays random characters instead
;; of your math, add the following line at the top of your Org file:
;; -*- coding: utf-8; -*-
;;
