=head1 NAME

dh_gencontrol - generate and install control file

=cut

use strict;
use Debian::Debhelper::Dh_Lib;

=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". 

=head1 OPTIONS

=over 4

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

=item B<--> I<params>

Pass "params" to L<dpkg-gencontrol(1)>.
