Eclipse

 
 
The Eclipse Workbench is an open source platform, designed by IBM and released to the open source community. It is an open, portable, universal tooling platform that provides frameworks, services and tools for building tools.

In essence the workbench provides the tool infrastructure. With this infrastructure in place, the tool builders are able to focus on the actual building of their tools. The workbench has been designed for maximum flexibility to support the development of tools for new technologies that may merge in the future.

Industry leaders Borland, IBM, Merchant, QNX Software Systems, Rational Software, RedHat, SuSE, TogetherSoft, and WebGain formed the initial eclipse.org board of directors and began work on the Eclipse open source project.
