Ouch. Some warning would have been nice... that move breaks all of the
automatic regression testing Troy has setup (about 5 boxes running
continuous builds of Boost via CMake, and submitting those results to a
Dart2 server). Troy's away, so it'll be a few days before he can tweak
the machines to deal with this change. Not catastrophic, but it'll slow
me down a bit :(

We'll fix those.

Yeah, we've become accustomed to checking out the whole sandbox.

And, eventually, moving those projects under
sandbox/projects/projectname.

Interesting.
