Looks like main_util is just placeholder stuff?

[oshima, 2014/05/16 20:14:13]

Yes, this is just a dummy impl until we have real one. Do you want me to rename
something more clear?

[Albert Bodenhamer, 2014/05/16 20:22:20]

Perhaps. When I see a file named "main_util.h/cc" I get the impression that
there are important pieces there.

Maybe just call it "dummy_app"?

renamed to just placeholder.h/cc as it does a bit more than app.
