The plan is to take a fresh look at the problem and to identify and fix low hanging fruits. Exploring parallelism is high on the agenda as well as fixing Makefiles and exploring some aggressive schemes like caching. I don't think that we should specifically limit the scope, though. - akolb _______________________________________________ tools-discuss mailing list tools-discuss@opensolaris.org
