Spelunking Apple’s Open Source
There’s no need to worry: the whole list, indexed by the pertinent platform and OS release to which they belong, is still available on a separate Releases page. Even better, each of these releases now has a corresponding GitHub repository, hosted in a dedicated organization reserved exclusively for open source distributions.

If you want to find the source code to an arcane tool like “banner”, just type it into a GitHub search of the organization. If there are too many false hits, as is the case for a common word like banner, try searching on something unique like a term from the command’s man page. The banner tool is credited as being authored by Mark Horton, and a search for “org:apple-oss-distributions Mark Horton” brings up more hits than I would have guessed (he also contributed to vim and vi, coincidentally), but a reference to the banner man page is the second search result.

Yup. I'm now using Apple's bootpd as my local DHCP server (because why not? It's perfectly already there, and perfectly usable, and clearly much more configurable than my router's dnsmasq installation) and I needed the source to figure out the leases file format. Not that I could not have guessed, or worked it out, by trial and error. But the source always helps. May the source be with you!
