you should not have to use stdio/iostream. Isn't LOG macro from base/logging
sufficient for usage here?

[mef, 2013/11/27 21:23:57]

Is there strong preference / suggestion of one vs another? It seems that
presubmit checks now discourage LOG in favor of VLOG, but that is probably
requiring special command line parameter...

[tbarzic, 2013/12/02 19:05:56]

Yes, there is a strong preference for using VLOG/LOG over std::cout.

[mef, 2013/12/02 20:03:20]

Done.
