/** TagLibConfiguration.
 * 
 * The class searches for TLD descriptors found in web.xml, in WEB-INF/*.tld files of the web app
 * or *.tld files withing jars found in WEB-INF/lib of the webapp.   Any listeners defined in these
 * tld's are added to the context.
 * 
 * <bile>This is total rubbish special case for JSPs! If there was a general use-case for web app
 * frameworks to register listeners directly, then a generic mechanism could have been added to the servlet
 * spec.  Instead some special purpose JSP support is required that breaks all sorts of encapsualtion rules as
 * the servlet container must go searching for and then parsing the descriptors for one particular framework.
 * It only appears to be used by JSF, which is being developed by the same developer who implemented this
 * feature in the first place!
 * </bile>
