Sirobot is a Perl script that downloads Web pages recursively. The main advantage over wget is its ability to get them concurrently, and is able to continue aborted downloads and convert absolute links to relative ones. It uses curses, can do HTTPS, and has a pattern-matching filter to prevent you from downloading the whole Internet.
