Server Options Set in the Database

Many optional behaviors of the server can be controlled from within the database by creating the property #0.server_options (also known as $server_options), assigning as its value a valid object number, and then defining various properties on that object. At a number of times, the server checks for whether the property $server_options exists and has an object number as its value. If so, then the server looks for a variety of other properties on that $server_options object and, if they exist, uses their values to control how the server operates.
