LinkController  

LinkController is a group of programs designed to take away much of the work of maintaining the links in a web site. Instead of the user running the program checking whether links are broken, LinkController does this automatically. When it finds a broken link it checks it several times across several days before reporting it broken. This means that if a link is repaired in the meantime (a common case), the user will never be bothered.
