Extra info and code examples

The motto of nn is its expanded name, which is "No News is good news, but nn is better", and the nn newsreader is designed to let you minimize the amount of time you spend reading news (or, more realistically, to allow you to follow even more newsgroups :-). Nn allows you to quickly select articles of interest and skip the rest. It also supports efficient article killing and selection of articles by author and subject. This version of nn reads news from a news server via NNTP (the Network News Transfer Protocol), and can make use of your NNTP server's NOV database, if configured. You must have a news server available - large sites usually provide a site-wide server. (For those familiar with 'nn', this is a client-only version.)
