The backend programs take articles that  innd  received  and  offer
them to your news neighbors.  This includes the following programs:

archive        A simple program to archive news articles.

batcher        Collects articles into batches for UUCP delivery.

buffchan       A program to split a single  innd  stream  into  separate
               files.   It  can  buffer  data,  flushing  files based on
               command-line switches.

crosspost      A  program  that  does  link  creation  for  cross-posted
               articles.  Runs  as a channel feed and lets innd hand off
               some of its i/o activity.

cvtbatch       A program to turn a file list into an INN  batchfile.   A
               transition aide that is only documented in the source.

filechan       Another program  to  split  a  single  innd  stream  into
               separate   files.    It  is  system-call  intensive,  but
               requires no locking protocol.

innxmit        A   replacement   for   nntpxmit   from   the   reference
               implementation.   It  reads  a  file containing a list of
               articles, and sends them to a host.

nntpget        A program to retrieve articles from a remote site.

shlock         A  program  to  provide  a  locking  protocol  for  shell
               scripts.

shrinkfile     A program to shrink a file by  removing  lines  from  the
               beginning.    It   is   useful   for  purging  backlogged
               batchfiles.

sys2nf         A program to turn a B or C News  sys  file  into  an  INN
               newsfeeds  file.   This is a transition aide that is only
               documented in the source.
