This is a list of environment variables that I scrounged up years ago. I no longer have any idea where they came from, or if the pages I got them off of used copious amounts of vaseline to convince people like me, back then, that they mean something useful. Whatever. The real deal for this server, right now, is nearer to the bottom of this page.
