CMake 2.8 comes with a CTest that can drive dashboards using git-based
work trees (plus hg and bzr).  The ctest_update() command runs "git pull"
to update the work tree, and reports file-wise changes.  It doesn't support
the nightly start time since that doesn't make sense for DVCS.  Nightly
builds currently just pull the latest version.
