+
+B<dh_dlopenlibdeps> [S<I<debhelper options>>] [B<-X>I<item>]
+
+=head1 DESCRIPTION
+
+B<dh_dlopenlibdeps> is a debhelper program that is responsible for calculating
+dlopen library dependencies for packages.
+
+This program follows the dlopen notes metadata specification as defined at
+https://systemd.io/ELF_PACKAGE_METADATA/
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<-X>I<item>, B<--exclude=>I<item>
+
+Exclude files that contain F<item> anywhere in their filename from being
+parsed. This will make their dependencies be ignored.
+This may be useful in some situations, but use it with caution. This option
+may be used more than once to exclude more than one thing.
