+=head1 SYNOPSIS
+
+B<dh_gencontrol> [S<I<debhelper options>>] [S<B<--> I<params>>]
+
+=head1 DESCRIPTION
+
+B<dh_gencontrol> is a debhelper program that is responsible for generating
+control files, and installing them into the I<DEBIAN> directory with the
+proper permissions.
+
+This program is merely a wrapper around L<dpkg-gencontrol(1)>, which calls
+it once for each package being acted on, and passes in some additional
+useful flags.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--> I<params>
+
+Pass I<params> to L<dpkg-gencontrol(1)>.
+
+=item B<-u>I<params>, B<--dpkg-gencontrol-params=>I<params>
+
+This is another way to pass I<params> to L<dpkg-gencontrol(1)>.
+It is deprecated; use B<--> instead.
