Usenet Downloader can be used to retrieve
newsgroup articles from NNTP servers. There is a
generic NNTP class that can retrieve listings of
groups, listing of group articles, and the article
headers and bodies. There are other classes that
can retrieve listing of groups from several
different sites and insert the listings into a
MySQL database table. Other classes can retrieve
groups stored in the database and retrieve
articles of those groups from the NNTP servers.
