=head1 SYNOPSIS

B<dh_gencontrol> [S<I<debhelper options>>] [S<B<--> I<params>>]

=head1 DESCRIPTION

dh_gencontrol is a debhelper program that is responsible for generating
control files, and installing them into the 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 including "-isp".

=over 4

=item B<-u>I<params>, B<--dpkg-gencontrol-params>=I<params>
