+=head1 SYNOPSIS
+
+B<dh_md5sums> [S<I<debhelper options>>] [B<-x>] [B<-X>I<item>] [B<--include-conffiles>]
+
+=head1 DESCRIPTION
+
+B<dh_md5sums> is a debhelper program that is responsible for generating
+a F<DEBIAN/md5sums> file, which lists the md5sums of each file in the package.
+These files are used by the B<debsums> package.
+
+All files in F<DEBIAN/> are omitted from the F<md5sums> file, as are all
+conffiles (unless you use the B<--include-conffiles> switch).
+
+The md5sums file is installed with proper permissions and ownerships.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-x>, B<--include-conffiles>
+
+Include conffiles in the md5sums list. Note that this information is
+redundant since it is included elsewhere in Debian packages.
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain I<item> anywhere in their filename from
+being listed in the md5sums file.
