/*
 *  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.
