Over time, the pages of a site may have to change to a different URL or even be removed.
Links pointing to changed or removed pages need to be updated. Otherwise, the links may lead the user to unpleasant error pages.
Updating links to the same site may be easier when the site is generated by a content management system. When the site pages are generated manually or the links point to other sites, the links need to be verified once in a while.
This package can help solving that problem. It checks the content of the site and verify whether each link still points to valid pages.
