// This class is a simple helper that does these things (and tears down the
// |AtExitManager| on destruction). Typically, it should be used in |MojoMain()|

// TODO(vtl): Maybe this should be called |ScopedBaseInit|, but for now I'm
// being consistent with everything else that refers to things that use //base
// as "chromium".
