.overview

Changi supports an overview database, which was originally designed by Geoff Collyer. It consists of files named .overview, one for each group, containing one line of header information for each article within this group.

Changi will create and update these files dynamically, when a group is accessed by a client. This may take some time if the group contains a large number of articles. Chanco oversync can be used to invoke a background thread on the server to update the overview files of all groups.

By default these files are stored in the newsgroup directories together with all article files. To reduce the load put on a single drive, you can specify a different directory for overview files by setting CHANGIOVERDIR.

The header information of each line contains the following items

each separated by a single tab character.

You may modify the contents of the overview files by creating a file named overview.fmt in CHANGIWORKDIR. But keep in mind that not every client may work with your specific format.
