There is none really. Perhaps I read bad/to fast but the idea was between changing the folder structures or hand copying maps. In a case where only a single file-string is the issue, than the solution I present with setting a flag like #ifdef for development/publish is pointless. The point being using this #ifdef you shouldn't need to either change the file structures nor hand copy maps. You simply end up running the 'publish mode twice. The idea would be worth more if you wish to create separate development structures and published structures, which covered many maps or files.

But as noted before, I'm weeks behind you 3run and not catching up..
