Comment (by Zweihorn):

 A quick and brief scan of the internet only showed, that the former Apple
 XCode documentary on making packages was taken down, apparently.

 A 'man pkgbuild' might help to find some more local info, I presume.

 However, IMO you will be the bigger experts and I trust your long-
 sightedness.
