NNTPspider searches for freely accessible NNTP
servers (free news servers) by using information
from the message headers. This search starts with
at least one default newsserver that you can
access, usually the one at your ISP. It reads the
Path: lines in the headers in order to find more
news servers. All the servers that are found are
checked for public access and queried for a list
of supplied newsgroups. This results in a quite
complete list of all news servers currently
availiable.
