GathererApplet4gs3.java was merged with GathererApplet.java, so that both the GLI applet code for GS2 and GS3 were in the single GathererApplet.java file. See http://trac.greenstone.org/browser/gli/trunk/src/org/greenstone/gatherer/GathererApplet4gs3.java?rev=17629, which was the last commit to GathererApplet4gs3 before it was meant to be removed from track
