LinkChecker is a web-master's dream come true. It not only takes in a list of links and tells you which ones are bad links, but it gets so specific as to tell you which ones redirect to other pages, which are forbidden access links, which are successful, and which are the old 'File Not Found' pages. The greatness doesn't end there! For you with rather large links lists and don't have time to finish it all (which is a very rare case because of the intense speed of this package) or maybe the system crashes, it supports a resume feature. This is an automatically implemented feature. It uses a DBM DB which enables such blazing fast speed.
