[3]  * The GNUstep project (http://www.gnustep.org/) is an effort of many different parties to deliver a free implementation of the OpenStep specification as published by NeXT & Sun companies in 1994. The motivation behind GNUstep is to make porting applications easier, to leverage the benefits of the Objective-C language, and to push the idea of OpenStep as a common object oriented API; especially on systems which are not covered by commercial implementations of this standard.
