+/*************************************************************
+ *
+ *  MathJax/extensions/jsMath2jax.js
+ *  
+ *  Implements a jsMath to Jax preprocessor that locates jsMath-style
+ *  <SPAN CLASS="math">...</SPAN> and <DIV CLASS="math">...</DIV> tags
+ *  and replaces them with SCRIPT tags for processing by MathJax.
+ *  (Note: use the tex2jax preprocessor to convert TeX delimiters or 
+ *  custom delimiters to MathJax SCRIPT tags.  This preprocessor is
+ *  only for the SPAN and DIV form of jsMath delimiters).
+ *  
+ *  To use this preprocessor, include "jsMath2jax.js" in the extensions
+ *  array in your config/MathJax.js file, or the MathJax.Hub.Config() call
+ *  in your HTML document.
