/* The Object class is a minimal (but fully functional) root class
included with the runtime.
It is mostly for testing the runtime; very handy in configure
tests, and when writing language/runtime testcases.
Because Objective-C allows multiple root classes, a Foundation
library (such as GNUstep-base) is expected to provide its own root
class (typically called NSObject), fully integrated with the
library's own high-level features. If you are using such a
Foundation library, you should most likely use its root class for
everything and ignore Object.
