## Name

deb-extra-override — Debian archive extra override file

## Synopsis

The extra override file is a whitespace-delimited text file. Comments are denoted with `#`.

## Description

The extra override file contains overrides for binary/source package fields that are applied when exporting to Packages/Sources files. Each line has three columns:

- `_package_` — name of the binary/source package
- `_field-name_` — name of the field to override
- `_value_` — value to put in the field (may contain spaces; line split into at most 3 columns)

The extra override files used for official Packages lists are in the `indices` directory on Debian mirrors.
