oh. you're right about that. I'm just adding it to be thorough and consistent. I have a symmetry with respect to my variables set up between "target" and "host" that I preserve if it makes sense to do so....whether or not it might actually be needed in practical terms. I think that is a useful policy when designing APIs.
At any rate, I have it coded to manually use "apple" since compatibility with other systems isn't a requirement.
Right now, I'm trying to figure out why configure_main is suddenly not being invoked. I broke something in the bowels I suppose. Once I get that fixed, I can submit this work for review....unless some other bug pops up.
