<!-- Targets for working from terminal window:
       build (default) - generates java files and compiles them
       test            - runs junit test cases
       clean           - removes all generated files and class files
       doc             - generates API documentation
     Targets for working from Eclipse:
       gen             - generates java files
       genClean        - removes all generated files and their class files
