When both are set to yes, the = effect is to keep all the build prerequisites (the sources, compiler, libra= ries, and other build-time tools) of live objects in the store, regardless = of whether these prerequisites are reachable from a GC root. This is conven= ient for developers since it saves rebuilds or downloads. Ouch, I should have RTFM, thanks a lot ! --=20 Vincent Legoll
