       rnews, cunbatch - accept and spool news input
       newsspool, newsrun - news input spooler and processing
       newsrunning - control news-processing daemon


       /usr/lib/news/input/newsspool [ -g grade ] [ file ... ]
       /usr/lib/news/input/newsrun [ -s suffixletter ] [ grades ]
       /usr/lib/news/input/newsrunning [on|off]


       Rnews accepts news from standard input and spools it up for processing,
       space permitting.  If space is persistently too short, rnews looks  for
       the  file  /var/lib/news/rnews.stall;  if  it  is  present, rnews waits
       patiently for more space to  appear,  while  if  it  is  absent,  rnews
       discards the news and reports this.

       Cunbatch  is  a historical synonym for rnews; there is no difference in
       what they do.

       Newsspool is the actual spooling program.  It copies the input  file(s)
       (standard  input  default)  to  a  file in the input-spooling directory
       /var/spool/news/in.coming, stripping off any ‘#! cunbatch’ header as it
       does  so.   The  filename  is  based on the current time, plus a suffix
       classifying the file  by  type  (compressed  or  plain  text),  plus  a
       possible  prefix denoting the one-digit numeric grade (if the -g option
       is given; rnews does not use this option).

       Newsrun should be run periodically (e.g. by cron(8)) to process spooled
       news.   Newsrunning can be used to turn newsrun’s processing off and on
       if it is desired to avoid major news processing during  certain  hours.
       ‘newsrunning  off’  instructs  any currently-running newsrun to stop as
       soon as possible, and prevents later ones from  running.   (This  is  a
       slight   oversimplification;  see  the  discussion  of  grades  below.)
       ‘newsrunning on’ removes the inhibition (but does not actually start  a
       new  newsrun).   Without  an  argument, newsrunning reports the current
       status: ‘‘off’’ or ‘‘on’’.

       Newsrun checks for the stop file that newsrunning off creates, verifies
       that  there  is  enough  disk  space  for  processing,  and then starts
       processing spooled news.  News is processed in order by grade:  if  the
       name  of the spooled file starts with a digit followed by a period, the
       digit is the file’s grade.  Files without a  grade  are  considered  to
       have  a  grade just after grade 9.  Lower-numbered grades are processed
       first, with processing within a grade in chronological order.

       If newsrun is invoked with a grades argument, that specifies the grades
       to be processed.  A grades argument can be a single grade (‘1’), a list
       (‘123’), or a range (‘1-5’).  In the absence of the argument, newsrun’s
       default  is all grades if there is no stop file present, and just grade
       0 if there is a stop file.  If a stop file appears  during  processing,
       newsrun  will  stop processing all but grade 0 and will exit when there
       is no grade-0 news left.

       If newsrun is run with a -s option, that restricts processing to  files
       that  end  with  .suffixletter  only.  For example, -s t would restrict
       processing to files classified as text only  (i.e.,  no  processing  of
       compressed files or unclassified files).

       Each  batch  is  decompressed (if necessary) and then fed to relaynews.
       (Files that  lack  a  classification  suffix,  typically  because  they
       arrived  by  some  means  other  than  newsspool,  are  tried  first as
       compressed and then  as  plain  text.)   If  relaynews  fails,  newsrun
       attempts  to  save  the spooled batch in the bad subdirectory for human

       Relaynews is a bit too enthusiastic about  declaring  batches  bad,  so
       things  may  end up in bad for no terribly good reason.  Actually, it’s
       rare for the contents of bad to be very interesting.

       The grading mechanism relies slightly on  collating  sequence,  and  in
       particular on ‘.’ collating before the digits.
