## GNUstep System Documentation

This is the system documentation for GNUstep, including both user and developer documentation. GNUstep provides an object-oriented application framework and tool set for use on a wide variety of computer platforms. It is based on the original OpenStep specification created by NeXT, Inc. (now Apple). (Top)

## Developer Documentation

The links here describe the development facilities provided under GNUstep. The Base Programming Manual introduces GNUstep as a whole, Objective-C, its main language, and the Base library, its basic set of non-graphical utility classes. The Make Utility makes project building easy and is highly recommended. The "API" links go to Javadoc-like reference pages on the Base and other GNUstep libraries.

## Development Tools

Project Center provides an integrated development environment (IDE) for GNUstep. Gorm is a graphical user interface construction tool. Using these, developers can quickly design and build cross-platform applications in Objective-C or Java.
