This section of the appendix details all configuration directives that can be defined in mt-config.cgi. Through use of these directives, you can control numerous aspects of the system.

Except for those which define things specific to your system (e.g. CGIPath and your database settings), all of them have defaults set by Movable Type. This means that not every directive will appear in mt-config.cgi. If you wish to override the default for a setting which does not appear in the file, simply add it and the desired value to your mt-config.cgi.
