public class JspRuntimeLibrary
extends java.lang.Object

Bunch of util methods that are used by code generated for useBean, getProperty and setProperty. The __begin, __end stuff is there so that the JSP engine can actually parse this file and inline them if people don't want runtime dependencies on this class. However, I'm not sure if that works so well right now. It got forgotten at some point. -akv
