and simply read the file in if it's there. It's super easy to edit in any given editor. And it's trivial to read in as well. You can loop through and build the array in what... 3 lines? And dumping it out is just as easy.
Don't over-engineer this. And yes, you are wise to not just blindly eval a document into the program. It sounds like a good app.
