+" Remark: see https://goaccess.io/man#configuration
+"
+" The GoAccess configuration file syntax is line-separated settings. Settings
+" are space-separated key value pairs. Comments are any line starting with a
+" hash mark.
+" Example: https://github.com/allinurl/goaccess/blob/master/config/goaccess.conf
+"
+" This syntax definition supports todo/fixme highlighting in comments, and
+" special (Keyword) highlighting if a setting's value is 'true' or 'false'.
+"
+" TODO: a value is required, so use extreme highlighting (e.g. bright red
+" background) if a setting is missing a value.
