gnustep Welcome to GNUstep Renaissance! GNUstep Renaissance is free software (GNU LGPL), and part of the GNUstep project. It is a development framework which runs on top of the GNUstep libraries. It also works on top of the Apple Mac OS X Cocoa libraries, providing an opaque layer to write portable applications. In short, GNUstep Renaissance allows you to describe your user interfaces (that is, the windows in your application, and the buttons, boxes, textfields, etc in the windows) in simple and intuitive XML files, using an open, standard format describing the logic of the interface. GNUstep Renaissance can then, at run time, generate the user interfaces (using the native host OpenStep-like libraries) by reading the XML files. The connections between the objects created from the XML files, and the other objects in the application are done via outlets (as traditionally in OpenStep); a new quick and intuitive syntax has been developed to make creating outlets as easy as possible.
