New "overview" text

[Scott Stevenson]

Some thoughts on this:

--------
"GNUstep provides an object-oriented application framework  and tool 
set for use on a wide variety of computer platforms. GNUstep is  not a 
window manager and it is not a desktop environment. However, there  are 
several efforts  [1]  [2] to  create a desktop environment based around 
GNUstep.  GNUstep is quite stable and used in production environments 
at many organizations."
--------

This is the first thing somebody might read about GNUstep, so it's 
pretty important to point out the shared lineage with Cocoa/OpenStep. 
Establishing that it's not a window manager seems secondary (and just a 
reflection of current events).


My suggestion would be:


"GNUstep is a cross-platform, object-oriented framework for desktop 
application development. Based on the OpenStep specification originally 
created by NeXT (now Apple), GNUstep enables developers to rapidly 
build sophisticated software by employing a large library of reusable 
software components. GNUstep is used in production environments at 
several organizations.

"GNUstep itself is not an operating system, window manager or desktop 
environment, though there are several desktop environments in 
development that are based on it. (More...)"


Just some thoughts.
