Lol, glad to see my code gets to survive a bit longer. LGTM, but I'm running a
Angle trybot just to make sure it builds correctly on Windows VS2010, since the
first time I used JSONCPP it somehow broke the build on those machines

Also you're missing the builderName/gitNumber/commitHash flags, but I'm guessing
that was part of the chickening out
