Nice demo. I already knew about how file works, how the "database" is
structured, and I've even tweaked it once or twice to handle new files
(Infocom game files, FWIW ;-), but I'd never tried a simple little
thing like that. I can see how it would work, but it just never
occurred to me to try that.
