Code review comment for lp:~termie/nova/mega_flags

Oh, I had already hassled him about it, but I think maybe since he has been traveling he didn't have a chance to click accept yet.

DECLARE is the syntax used in the C version of gflags. It's meaning is that you are declaring that you will be using a given flag. It's syntax varies slightly from that of the C version in that C has everything in the same namespace and is generally all compiled together where as in python the flag may not already be loaded so it will make sure it is. This is also in line with the DECLARE_key_flag syntax.
