19 B<dh_md5sums> is a debhelper program that is responsible for generating
20 a F<DEBIAN/md5sums> file, which lists the md5sums of each file in the package.
21 These files are used by the B<debsums> package.
23 All files in F<DEBIAN/> are omitted from the F<md5sums> file, as are all
24 conffiles (unless you use the B<--include-conffiles> switch).
26 The md5sums file is installed with proper permissions and ownerships.
32 =item B<-x>, B<--include-conffiles>
34 Include conffiles in the md5sums list. Note that this information is
35 redundant since it is included elsewhere in Debian packages.
37 =item B<-X>I<item>, B<--exclude=>I<item>
39 Exclude files that contain I<item> anywhere in their filename from
40 being listed in the md5sums file.
