Dorian's tweaks for jarification, plus a MANIFEST file that allows building a jar without the need for reshuffling all the files. If your IDEs complain, ensure you set the "working directory" to the /bin directory when you run the project (IDEs can sometimes default to the source directory on this one, which probably explains why Dorian had such trouble making this work last week).
The jar that is compiled from this works, though (Yay!)
