      6  *  MathJax/config/MMLorHTML.js
      7  *  
      8  *  Chooses between the NativeMML and HTML-CSS output jax depending
      9  *  on the capabilities of the browser and configuration settings
     10  *  of the page.
     11  *  
     12  *  This file should be added to the config array when configuring
     13  *  MathJax.  Note that if you include this, you should NOT include
     14  *  an output jax in the jax array (it will be added for you by
     15  *  this file).
     16  *  
     17  *  You can specify the preferred output jax on a global or
     18  *  browser-by-browser basis.  To specify it globally, use
     19  *  
     20  *      MathJax.Hub.Config({
     21  *        MMLorHTML: {prefer: "MML"} // or "HTML"
     22  *      });
     23  *  
     24  *  To specify on a browser-by-borwser basis, use
     25  *  
     26  *      MathJax.Hub.Config({
     27  *        MMLorHTML: {prefer: {
     28  *          MSIE:    "MML",
     29  *          Firefox: "MML",
     30  *          Opera:   "HTML",
     31  *          other:   "HTML"
     32  *        }}
     33  *      });
