Eclipse Rich Client Platform (RCP)
The Eclipse Platform is an open and extensible platform for anything and yet nothing in particular. It provides a foundation for constructing and running integrated software-development tools. The Eclipse Platform allows tool builders to independently develop tools that integrate with other people's tools so seamlessly you can't tell where one tool ends and another starts. . This package includes the Eclipse Rich Client Platform (RCP), the basis upon which Eclipse RCP applications are built.
