| % Administrative process for MGW NAT |
| |
| % The administrative process takes care of re-loading the configuration |
| % after it has been re-parsed. This includes delivering a reload_config |
| % signal to all child processes of the supervisor. We don't do this |
| % inside the supervisor itself, as there might be an exception. |
