		git clone https://github.com/mozilla/rhino.git
		cd rhino
	(2) Change string references to class:
		perl -p -i -e 's/org\/mozilla\//org\/eclipsescript\/rhino\//g' `find ./ -name *.java`
	(3) Build:
		ant jar
	(4) 
		cp build/rhino1_7R5pre/js.jar $ECLIPSESCRIPT/js_orig.jar
		cd $ECLIPSESCRIPT
		ant -f build_js_with_jarjar.xml
