=head1 NAME

dh_installdeb - install files into the DEBIAN directory

=cut

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

=head1 SYNOPSIS

  dh_installdeb [debhelper options]

=head1 DESCRIPTION

dh_installdeb is a debhelper program that is responsible for installing
files into the DEBIAN directories in package build directories with the
correct permissions.

dh_installdeb automatically installs the following files from debian/ into
the DEBIAN directory:
  package.postinst
  package.preinst
  package.postrm
  package.prerm
  package.shlibs
  package.conffiles

The postinst, preinst, postrm, and prerm are handled specially: If a
corresponding file named debian/script.debhelper exists, the contents of that
file are merged into the script as follows: If the script exists, then
anywhere in it that "#DEBHELPER#" appears, the text of the .debhelper file is
inserted. If the script does not exist, then a script is generated from
the .debhelper file. The .debhelper files are created by other debhelper
programs, such as L<dh_installmenu(1)>, and are shell script fragments.

If DH_COMPAT is set to 3 or higher, all files in the etc/ directory in a
package will automatically be flagged as conffiles by this program, so
there is no need to list them manually in package.conffiles.
