dh_md5sums is a debhelper program that is responsible for generating
a DEBIAN/md5sums file, which lists the md5sums of each file in the package.
These files are used by the debsums package.
All files in DEBIAN/ are omitted from the md5sums file, as are all
conffiles (unless you use the --include-conffiles switch).
The md5sums file is installed with proper permissions and ownerships.
OPTIONS
-x, --include-conffiles
Include conffiles in the md5sums list. Note that this information is
redundant since it is included elsewhere in debian packages.
-Xitem, --exclude=item
Exclude files that contain ``item'' anywhere in their filename from
being listed in the md5sums file.
