This file is used for integrity verification and deduplication purposes, and not for any kind of security purpose. This file contains a list of MD5 digests (as 32 case-insensitive hexadecimal characters) followed by two spaces (U+0020 B<SPACE>) and the absolute pathname of a plain file, one per line. Trailing slashes (U+002F B</>) in the pathname will be trimmed. Neither trailing whitespace nor empty or whitespace-only lines are accepted. If the control file does not exist in the binary package, L<dpkg(1)> will generate the matching information at unpack time (since B<dpkg> 1.16.3). =head1 EXAMPLE 53c0d4afe4bc4eccb5cb234d2e06ef4d usr/bin/dpkg f8da2bc74cdcad8b81c48a4f0d7bb0a8 usr/bin/dpkg-deb 70b913132de56e95e75de504979309b4 usr/bin/dpkg-divert […] =head1 SEE ALSO L<md5sum(1)>, L<dpkg-deb(1)>, L<dpkg(1)>.
