stud does not have any configuration file. You can setup some options
in "/etc/default/stud" then configure any number of stud instances by
creating configuration files in /etc/stud. Those files should be
suffixed by ".conf" and must define two variables: OPTIONS and CERT.

For example:

OPTIONS="-f *,443 -b 127.0.0.1,8445"
CERT="/etc/ssl/stud.pem"
