Leech was developed to relieve one from having to go through sites, constantly clicking "Save As...", "OK", etc. Instead, feed Leech a URL and tell it which filetypes to download, and it will crawl through any page that meets Leech's restrictions and dowload any file of the specified type.

For those of you who are having trouble with regular expressions, try this brief tutorial (http://www.zytrax.com/tech/web/regex.htm). It's not too accurate though.
