So the answer to "How do I find the source to the ls command?" is "click around a web site perusing long lists of packages, trying one after another in an effort to figure out which one the ls command is from, then manually download nine files one by one from http://opensource.apple.com/source/file_cmds/file_cmds-212/l...? Is that a fucking joke? If that's your idea of fun, go ahead, but I have a computer to do that kind of thing for me. I have an operating system with package management, not a hobby.

Perhaps this has changed since the last time I did it, a couple of years ago; it did then.
