Mario is waiting on Roberto to get a list of reco tools which can be re-used in the rewriting of the drift chamber simulation ready for G4. Hope is that will get feedback in a few days.
DRC code is basically stable.
No problems are anticipated in transition to G4 because the cerenkov angle calc code is independant of BBsim. Dave sas been looking into changes in gustep code to output info needed to study backgrounds. This may or may not be controversial. Changes needed to turn on output of all of truth tree are in prodfiles - no feedback yet on whether requested runs will be done. Request is in list - need to check on mechanism for getting run.
