This link leads to (when trying to go to the page)

HTTP Status: 404 (not found)

with a link checker this leads to the error:

  Code: 405 Not Allowed
 To do: The server does not allow HTTP HEAD requests, which prevents the
        Link Checker to check the link automatically.  Check the link
        manually.

Please advise what to do with the link or make the comment block a non doxygen comment block.
