Well, just for one, I tried building phobos docs a couple of days 
ago while disconnected from the internet; the whole thing failed 
because the clones of stable release repos couldn't be done.

No doubt I'm missing a trick, but it didn't seem very obvious, on 
browsing the makefile, what would get me the simple case of 
building the development phobos docs using my development dmd, 
without needing to worry about any of the other options out there.
