I am about to collapse all controlled units in the uml directory. The aim is to merge all units into a single file and then place a copy into the i3_old directory. This means we will lose change history but its no big deal because its only being kept for a historical reference. Any unused packages will be removed from the current uml area. Let me know if you are doing anything with the UML model. Because you changes will be lost. This will hopefully only take an hour or two. Cheers, Alex.
