NAME
       overchan	- Batch	update the INN overview	database

SYNOPSIS
       overchan	[file ...]

DESCRIPTION
       overchan	reads overview data from the specified files or	from standard
       input if	no files are specified,	and writes that	data into the INN
       overview	database.  (The	file "-" means to read data from standard
       input as	well.)

       Normally, overview data is stored by innd for articles as they're
       accepted.  For performance, however, it's sometimes useful to have
       overview	data written by	a separate process.  To	do this, set
       useoverchan to true in inn.conf to tell innd to not write overview data
       directly	and then add an	overchan channel in newsfeeds:

	   overview!:*:Tc,WnteO:<pathbin>/overchan

       where <pathbin> is pathbin in inn.conf.	Additionally, overchan can be
       used to bulk-load overview data from appropriately formatted batch
       files (such as overflow files from an overchan channel).

       Each line of input should have the following format:

	   <token> <arrived> <expires> <data>

       where <token> is	the storage API	token of the article in	textual	form
       (surrounded by "@" characters), <arrived> is the	arrival	timestamp of
       the article in seconds since epoch, <expires> is	the expiration time of
       the article in seconds since epoch or 0 if there	is none, and <data> is
       the tab-separated overview data.	 Each of these fields must be
       separated by a single space.
