I'd be pretty frightened if someone needed to use OOP in their distribution script. :-) The JavaScript snippets run by the installer are supposed to be very short functions that inspect some properties of the system, packages, or user's selections, and typically return true or false. I hope that the C like syntax plus native string support makes doing that as painless as possible for our developers. This email sent to site_archiver(a)lists.apple.com

I keep a Safari toolbar shortcut to it.) Actually, this is one of the issue with the documentation. Previously, the documentation related to Software Installation was found in http://developer.apple.com/reference/UserExperience/ idxFilesSoftwareInstallation-date.html. And sure you can find the Installer JavaScript Reference documentation there too. But nothing for the Distribution Script reference (which is outdated or missing multiple attributes and tags).
