=head1 NAME
dh_gencontrol - generate and install control file
=cut
use strict;
use warnings;
use Debian::Debhelper::Dh_Lib;
our $VERSION = DH_BUILTIN_VERSION;
=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.
