openSUSE:Build Service KDE Rich Client
A rich client for the build service is developed by Jonathan Arsenault as part of Google's Summer of Code 2006.
Programmed as a c++ QT/KDE GUI application to help user of the opensuse build service, communication with the server is done in xml using kio_slave. Currently viewing of project listing, project metada and some data about their package should work.
Writing of those data back to server is currently in development :\
