/* 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.
