=head1 NAME
dh_installdeb - install files into the DEBIAN directory
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installdeb> [S<I<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/package.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.
In V3 compatibility mode and 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.
