There are now two prototype systems, one being put together by Tony and one by Matt. We are trying to coordinate to not duplicate too much effort, and will choose the best aspects of each system. They can be found at:
http://web007.slac.stanford.edu:8888/SystemTests/
http://glast-ground.slac.stanford.edu/systest
New features are being added to both systems for a few more days, then we will start the merge process, and aim to have a working system by 15th January.
