RFC977 3.8.1.  NEWNEWS

   NEWNEWS newsgroups date time [GMT] [<distribution>]

   A list of message-ids of articles posted or received to the specified
   newsgroup since "date" will be listed. The format of the listing will
   be one message-id per line, as though text were being sent.  A single
   line consisting solely of one period followed by CR-LF will terminate
   the list.

   Date and time are in the same format as the NEWGROUPS command.

   A newsgroup name containing a "*" (an asterisk) may be specified to
   broaden the article search to some or all newsgroups.  The asterisk
   will be extended to match any part of a newsgroup name (e.g.,
   net.micro* will match net.micro.wombat, net.micro.apple, etc). Thus
   if only an asterisk is given as the newsgroup name, all newsgroups
   will be searched for new news.

   (Please note that the asterisk "*" expansion is a general
   replacement; in particular, the specification of e.g., net.*.unix
   should be correctly expanded to embrace names such as net.wombat.unix
   and net.whocares.unix.)

   Conversely, if no asterisk appears in a given newsgroup name, only
   the specified newsgroup will be searched for new articles. Newsgroup
   names must be chosen from those returned in the listing of available
   groups.  Multiple newsgroup names (including a "*") may be specified
   in this command, separated by a comma.  No comma shall appear after
   the last newsgroup in the list.  [Implementors are cautioned to keep
   the 512 character command length limit in mind.]

   The exclamation point ("!") may be used to negate a match. This can
   be used to selectively omit certain newsgroups from an otherwise
   larger list.  For example, a newsgroups specification of
   "net.*,mod.*,!mod.map.*" would specify that all net.<anything> and
   all mod.<anything> EXCEPT mod.map.<anything> newsgroup names would be
   matched.  If used, the exclamation point must appear as the first
   character of the given newsgroup name or pattern.

   The optional parameter "distributions" is a list of distribution
   groups, enclosed in angle brackets.  If specified, the distribution
   portion of an article's newsgroup (e.g, 'net' in 'net.wombat') will
   be examined for a match with the distribution categories listed, and
   only those articles which have at least one newsgroup belonging to

   the list of distributions will be listed.  If more than one
   distribution group is to be supplied, they must be separated by
   commas within the angle brackets.

   The use of the IHAVE, NEWNEWS, and NEWGROUPS commands to distribute
   news is discussed in an earlier part of this document.

   Please note that an empty list (i.e., the text body returned by this
   command consists only of the terminating period) is a possible valid
   response, and indicates that there is currently no new news.
