OVERCHAN(8)
NAME
  overchan - update the news overview database

SYNOPSIS
  overchan [ file ...  ]

DESCRIPTION
  Overchan reads article data from files or standard input if none are
  specified.  (A single dash in the file list means to read standard input.)
  It uses this information to update the news overview database.  Overchan
  was originally designed to be used by InterNetNews or the C News ``mkov''
  packages to update the database as the articles come in.  For current INN,
  the database is stored in a selected overview method.	 This can be done
  within innd(8) itself, but overchan(8) can be used instead, if <useoverchan
  in inn.conf> is ``true'' and appropriate setup is done in newsfeeds, for
  example:

       overview!:*:Tc,WnteO:<pathbin in inn.conf>/overchan

  Overchan input data consists of a line of text, separated into four parts
  by a space.  The first part is a token for the article.  The second part is
  time when the article was received.  The third part is time when the
  article will be expired (which represents the Expires header).  The fourth
  part is the data to be stored.

  The data in the overview files should be expired by running expireover(8).
  This is normally done by adding the ``expireover'' flag to the
  news.daily(8) invocation.
