 * I use the Apache config file's ServerAdmin value (which becomes $_SERVER['SERVER_ADMIN'] in PHP global)
 * to determine if we're running in production environment, dev environment, and so on.
 * This is by no means a best practice, but just one of the easier ways to have multiple environments
 * running off the same codebase.
