From Andres Garcia:
Getleft for Linux is a web site grabber, given an URL, it will download the complete site according to the options given by the user. While it goes, it changes the original pages, all the links get changed to relative links, so that you can surf the site in your hard disk. Limited Ftp support, it will download the files but not recursively. Resumes downloading if interrupted. Filters not to download certain kind of files. You can get a site map before downloading. Getleft can follow links to external sites.
