The "news" system is composed of various groups where people can read posts
from others and post their own notes.  Because all groups may not be of
interest to you, you have the option of "subscribing to" only the ones you are
interested in.  Only subscribed-to groups will be scanned for new posts when
you enter the news system and/or read all new posts.  For more information
(including a list of commands) on how to use news, use the "?" command after
entering the news system.

If used with "-n" as an argument, the "news" command checks for any new posts,
reports what was found, and then exits.
