-    To get jQuery even smaller, remove the modules you don't need by removing the fileset elements
-	in the jquery-target, for example leaving only these:
-
-	<fileset dir="${SRC_DIR}" includes="intro.js" />
-    <fileset dir="${SRC_DIR}" includes="core.js" />
-    <fileset dir="${SRC_DIR}" includes="selector.js" />
-    <fileset dir="${SRC_DIR}" includes="event.js" />
-    <fileset dir="${SRC_DIR}" includes="outro.js" />
-
-	That'd remove ajax, fx and offset support, leaving basic selectors, manipulation and event handling.
