BTW, I have not given any thought to what happens to these variables/paths if you run '--recursive'. I assume the new 'recursed' submodule takes on the role of the 'superproject' in the definitions above. Hmm, but what does $dpath show? (having 'recursed', is the cwd now at the top level of the 'new' superproject?) Hmm, you have changed several command to recurse into submodule(s) (I haven't followed that effort closely), so I suppose it should have some measure of consistency with those commands. (whatever that means ;-) ATB, Ramsay Jones
