Snapshotted from 5e7fd50e17b6edf1cadff973d0ec68966cf3265e in the upstream repository: https://github.com/google/googletest Since standalone builds and bots will need this, checking in a copy rather than require everyone use gclient, repo, git submodules or scary CMake scripts is probably simplest. Consumers with their own copies of googletest will likely wish to ignore or even exclude this directory.
