Description:
GNUstep Workspace Manager
GWorkspace is the official GNUstep workspace manager. It is a clone of NeXT's workspace manager. GWorkspace is probably one of the most useful and usable workspace managers available on any platform, owing to its well-designed interface and the natural, consistent design that it inherits from the GNUstep framework.
