+owner-filter::
+ Specifies a command which will be invoked to format the Owner
+ column of the main page. The command will get the owner on STDIN,
+ and the STDOUT from the command will be included verbatim in the
+ table. This can be used to link to additional context such as an
+ owners home page. When active this filter is used instead of the
+ default owner query url. Default value: none.
+ See also: "FILTER API".
