"The IBM Reflexive User Interface Builder (RIB), a new technology available
from alphaWorks, is an application and toolkit for building and rendering
Java AWT/Swing and Eclipse SWT GUIs. RIB specifies a flexible and
easy-to-use XML markup language for describing Java GUIs and provides an
engine for creating them. You can use RIB to test and evaluate basic GUI
layout and functionality, or to create and render GUIs for an application."
