Batch USENET news reader with filter capabilities

From the README: newsfish, quite simply, is a batch USENET news reader. In other words, it is not interactive, and it has a very simple user interface. The power of newsfish is that it can sift through articles and save only the ones that match your criteria. It does this by applying a set of regular expressions (a la grep/egrep) to the headers of each article. Articles are saved in mailbox format, which makes them suitable for viewing under most popular mail readers.
