=head1 NAME
dh_installdeb - install files into the DEBIAN directory
=cut
use strict;
use warnings;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installdeb> [S<I<debhelper options>>]
=head1 DESCRIPTION
B<dh_installdeb> is a debhelper program that is responsible for installing
files into the F<DEBIAN> directories in package build directories with the
correct permissions.
=head1 FILES
=over 4
=item I<package>.postinst
=item I<package>.preinst
=item I<package>.postrm
=item I<package>.prerm
These maintainer scripts are installed into the F<DEBIAN> directory.
Inside the scripts, the token B<#DEBHELPER#> is replaced with
shell script snippets generated by other debhelper commands.
=item I<package>.triggers
=item I<package>.shlibs
These control files are installed into the F<DEBIAN> directory.
Note that I<package>.shlibs is only installed in compat level 9 and
earlier. In compat 10, please use L<dh_makeshlibs(1)>.
=item I<package>.conffiles
This control file will be installed into the F<DEBIAN> directory.
In v3 compatibility mode and higher, all files in the F<etc/> directory in a
package will automatically be flagged as conffiles by this program, so
there is no need to list them manually here.
=item I<package>.maintscript
Lines in this file correspond to L<dpkg-maintscript-helper(1)>
commands and parameters. However, the "maint-script-parameters"
should I<not> be included as debhelper will add those automatically.
Example:
# Correct
rm_conffile /etc/obsolete.conf 0.2~ foo
# INCORRECT
rm_conffile /etc/obsolete.conf 0.2~ foo -- "$@"
In compat 10 or later, any shell metacharacters will be escaped, so
arbitrary shell code cannot be inserted here. For example, a line
such as C<mv_conffile /etc/oldconffile /etc/newconffile> will insert
maintainer script snippets into all maintainer scripts sufficient to
move that conffile.
It was also the intention to escape shell metacharacters in previous
compat levels. However, it did not work properly and as such it was
possible to embed arbitrary shell code in earlier compat levels.
