/* The Object class is a very minimal root class included with the
runtime. It is used as superclass for the two classes included
with the runtime, Protocol and NXConstantString.
Because Objective-C allows multiple root classes, you can define
your own root class, different from Object.
In particular, 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. It is
expected that you should always use and interact with NSObject, and
mostly ignore Object. */
