Server configuration

Is there a definitive list of commands that can be placed in the .cfg for server-side control? Most of what I’m finding is geared towards legacy, and what’s left is a basic install guide.

EDIT: Found it, woot! http://www.rustafied.com/rust-experimental-guides/#/how-to-host-your-own-rust-server/

Can anyone give me some guidance on some of the ranges? Specifically, what does the “1” in spawn.max_rate relate to? Is that one spawn per in-game day cycle?
