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.
