All reports of package-contains-info-dir-file for the archive. The extended description of this tag is:
This package contains a file named dir or dir.old, possibly compressed, in /usr/share/info. This is the directory (or backup) of info pages and is generated automatically by install-info when a package containing info documentation is installed. Some upstream build systems create it automatically, but it must not be included in a package since it needs to be generated dynamically based on the installed info files on the system.
This tag has not been emitted in any package tested by Lintian.
