+/*
+ *  extensions/autobold.js
+ *  
+ *  Part of the jsMath package for mathematics on the web.
+ *
+ *  This file causes jsMath to use \boldsymbol{...} around mathematics
+ *  that appears within <B>...</B> tags or has font-weight:bold applied
+ *  via CSS rule.  You can activate it by calling
+ *  
+ *    jsMath.Extension.Require('autobold');
+ *    
+ *  once jsMath.js has been loaded, or by adding "extensions/autobold.js"
+ *  to the loadFiles array in jsMath/easy/load.js.
+ *  
+ *  Note that you will need to install the cmmib10 and cmbsy10 fonts
+ *  that are available from the jsMath extra font page at
+ *  
+ *      http://www.math.union.edu/locate/jsMath/download/extra-fonts/
+ *
+ *  to make this work in image mode.  Note that there is no unicode
+ *  fallback for these fonts at the moment.
