description =

Defines the type of messages that should be logged, and down to
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.
