GNUstep, OpenStep and Cocoa
If you are new to the OpenStep programming Environment you should
probably check the following links to get a broad overview.
This is the official GNUstep homepage. Should be the first
site to visit if you are new to GNUstep.
Apple Developer Page:
A wealth of documentation and sample code. Also includes a decent
introduction to Objective-C. Note that Cocoa is a successor of OpenStep
that contains many additional classes. Not all of the information you
will find here will also apply to GNUstep.
Articles, Tutorials, Reference Manuals
A page that already existed in the early OpenStep days. Here you
will find many useful articles and tutorials most of which will be
fully applicable to GNUstep.
As the name already implies this page is focused on Cocoa. In
spite of this you will find many tutorials here detailling the
interesting aspects of OpenStep foundation classes.
