Hmm. Does FaceSpan really make sense anymore in times of (free) AppleScript Studio? AppleScript Studio can also create completely AppleScript-based software, and with the help of Interface Builder there's also a very good GUI design tool, and the integration is also very high. And above all, extensions and performance-critical areas can be implemented quite easily in Objective-C. I don't know if FaceSpan really makes sense there anymore.
At welcome to macscripter.net | applescript and script resource there's the original article.
