+=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 (plus related dbgsym
+packages), and passes in some additional useful flags.
+
+B<Note> that if you use B<dh_gencontrol>, you must also use
+L<dh_builddeb(1)> to build the packages.  Otherwise, your build may
+fail to build as B<dh_gencontrol> (via L<dpkg-gencontrol(1)>) declares
+which packages are built.  As debhelper automatically generates dbgsym
+packages, it some times adds additional packages, which will be built
+by L<dh_builddeb(1)>.
+
+
+=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.
