 KLinkStatus is KDE's web link validity checker. It allows you to
 search internal and external links throughout your web site. Simply
 point it to a single page and choose the depth to search.

 You can also check local files, or files over ftp:, fish: or any other
 KIO protocols. For performance, links can be checked simultaneously.
