Well, I use snapshot views for all of my day to day building, nightly
builds and whatnot. It's faster to populate a snapshot and build from
it than it is to build from a dynamic view.

I use the dynamic views for merging between streams, where I really
want the power of ClearCase. The real secret is that you can have both
a dynamic view and a snapshot view both using the same stream.

We've changed source code control systems several times, and still
occaisonally use a different one, so I'd much rather use GNU make,
which is agnostic to the source code control system being used (that's
my on-topic blurb).
