Extensible Tool Platform and Java IDE
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 provides the whole Eclipse SDK that contains Eclipse Platform, Java development tools and Plug-in Development Environment, including source and both user and programmer documentation.
