+ * smallFonts.js
+ *
+ * Part of the jsMath package for mathematics on the web.
+ *
+ * This file changes the sizes of fonts used in subscripts so that they
+ * are larger. This can be helpful if jsMath is used on a page with a
+ * small font size, where the subscripts may tend to disappear.
+ * It should be loaded BEFORE jsMath.js.
