I don't understand GNUstep, even after going to the project's homepage and reading a bit I don't understand it. Are there any applications right now that are using it? And I mean real applications that are actually used by someone else besides the developer, not some proof of concept application done over a weekend to try it out. I saw a small list of applications on the project's site but they all look like they came out of a 1989 Unix computer. Is it by design that they all look like crap? Can GNUStep be used to easily port actual Mac OS applications to other OSes or would those applications have to be rewritten from scratch for that?
