The Workbench provides the user interface structure for Eclipse. The purpose of the Workbench is to facilitate the seamless integration of tools. These tools contribute to extension points defined by the Workbench. The Workbench is responsible for the presentation and coordination of the user interface. The tools metaphor is not specific to development tools, but can apply equally well to arbitrary applications. Note that the Workbench is sometimes called the Generic Workbench, to distinguish it from its instantiation in the Eclipse IDE, where it is called the IDE Workbench.
