Now, this still leaves me wondering how to combine them into a single bundle. I mean, I know how to script the part where I lipo the various parts together, but I'm not sure how to get the proper signing done, other than copying the output of xcodebuild. We can have separate distributions for now (until and unless Apple lets me use the Endpoint Security Framework for real, we can't be feature-complete, or at least feature-parity with Windows, anyway).
