UNgrabber is a search engine for the binary usenet newsgroups. Usually one would have to download gigabytes of headers from thousands of binary newsgroups to be able to search for a file. Using this client its a matter of seconds - start it up, enter some search words and you are done with it. Just select the articles you are interested in and let ungrabber create a NZB file. This NZB file can be imported into almost any recent usenet client and will let it download the files.
