Slashdot has a link to an article at LinuxFocus.org about the history of GNUstep. "More than 10 years ago, an incredible machine with an even more incredible OS was released. It
was called NeXT and NeXTStep was the name of the OS. We had never seen something like that
before: it was a very nicely designed machine, with a breathtaking display. The OS was based on
BSD 4.2 at the beginning and 4.3 a bit later, with a very compact mach kernel. With it, appeared the
first graphical and object oriented development tool : Interface Builder ... Then, NeXT decided to port the framework to different OSes such as Sun,
for instance. This API was called OpenStep. From there, GNU started a big project, GNUstep,
http://www.gnustep.org, to build a free OpenStep implementation."
