  7. * Chooses between the NativeMML and HTML-CSS output jax depending
  8. * on the capabilities of the browser and configuration settings
  9. * of the page.
  10. *
  11. * This file should be added to the config array when configuring
  12. * MathJax. Note that if you include this, you should NOT include
  13. * an output jax in the jax array (it will be added for you by
  14. * this file).
  15. *
  16. * You can specify the preferred output jax on a global or
  17. * browser-by-browser basis. To specify it globally, use
  18. *
  19. * MathJax.Hub.Config({
  20. * MMLorHTML: {prefer: "MML"} // or "HTML"
  21. * });
  22. *
  23. * To specify on a browser-by-borwser basis, use
  24. *
  25. * MathJax.Hub.Config({
  26. * MMLorHTML: {prefer: {
  27. * MSIE: "MML",
  28. * Firefox: "MML",
  29. * Opera: "HTML",
  30. * other: "HTML"
  31. * }}
  32. * });
