Usage: ./make.sh command

All commands complete any required earlier steps, with the effect that a
./make install will compile the java code, make a jar file, put it in an
app wrapper and move the app to the Applications folder.

Main Commands:
compile     Compile the java code
jar         Make a jar file
clean       Delete the files and folders creeated by this script (if any)
            Non including the installed application.

Mac Commands:
app         Make a simple mac app wrapper for the jar
install     Move the app to the /Applications folder

Other Commands:
test        Delete the existing build, compile and run
run         Compile (if necessary) and run
