OVERCHAN(8)OVERCHAN(8)NAMEoverchan - update the news overview database
SYNOPSISoverchan [ - | 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 origi
nally 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 by
overview method. This can be done within innd(8) but,
still overchan(8) can do this, if <useoverchan in
inn.conf> is ``true'' and appropriate setup is done in
newsfeeds(5). file, for example:
overview!:*:Tc,WnteO:<pathbin in inn.conf>/overchan
This data consists of a line of text, separated into four
parts by a space. The first part is a token for the arti
cle. The second part is time when the article was
received. The third part is time when the article will be
expired(which represents 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 nor
mally done by adding the ``expireover'' flag to the
news.daily(8) invocation.
