  16 =head1 DESCRIPTION
  17
  18 dh_gencontrol is a debhelper program that is responsible for generating
  19 control files, and installing them into the DEBIAN directory with the
  20 proper permissions.
  21
  22 This program is merely a wrapper around L<dpkg-gencontrol(1)>, which calls
  23 it once for each package being acted on, and passes in some additional
  24 useful flags.

  35
  36 This is another way to pass I<params> to L<dpkg-deb(1)>.
  37 It is deprecated; use B<--> instead.
