+          which level of importance they should be considered.
+
+          The possible types are “artwork”, “database”, “general”, “http”,
+          “inotify”, “metadata”, “scanner”, “ssdp” and “tivo”.
+
+          The levels are “off”, “fatal”, “error”, “warn”, “info” and
+          “debug”, listed here in order of decreasing importance.  “off”
+          turns off logging messages entirely, “fatal” logs the most
+          critical messages only, and so on down to “debug” that logs every
+          single messages.
+
+          The types are comma-separated, followed by an equal sign (‘=’),
+          followed by a level that applies to the preceding types. This can
+          be repeated, separating each of these constructs with a comma.
+
+          Defaults to “general,artwork,database,inotify,scanner,metadata,
+          http,ssdp,tivo=warn” which logs every type of message at the
+          “warn” level.
