+"""Initialize all global state.
+
+Every entrance into the Mailman system, be it by command line, mail program,
+or cgi, must call the initialize function here in order for the system's
+global state to be set up properly.  Typically this is called after command
+line argument parsing, since some of the initialization behavior is controlled
+by the command line arguments.
