=head1 NAME
dh_installdebconf - install files used by debconf in package build directories
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_installdebconf> [S<I<debhelper options>>] [B<-n>] [S<B<--> I<params>>]
=head1 DESCRIPTION
dh_installdebconf is a debhelper program that is responsible for installing
files used by the debconf package into package build directories.
It also automatically generates the postrm commands needed to
interface with debconf. See L<dh_installdeb(1)> for an explanation of how
that works.
Files named debian/package.config and debian/package.templates are
installed into the DEBIAN directory in the package build directory.
Note that if you use debconf, your package probably needs to depend on it
(it will be added to ${misc:Depends} by this program).
Note that for your config script to be called by dpkg, your postinst
needs to source debconf's confmodule. dh_installdebconf does not
install this statement into postinst automatically as it it too hard to
do it right.
=head1 LOCALIZED TEMPLATE FILES
Debconf also supports localized template files, and this program has some
support to aid is working with them. It is best to keep the translations in
.po files under debian/po, and merge them only at build time. See
L<po2debconf(1)> and L<debconf-getlang(1)> for details.
This program will look to see if you have a debian/po directory and if so will
automatically call L<po2debconf(1)> to generate a merged templates file. Or
if you have debian/templates.ll files, it will use the older
L<debconf-mergetemplate(1)> program to merge those together.
Note that if your package has a debian/po directory it should build-depend on po-debconf.
For example, if you have a German translation,
strings from debian/po/de.po are merged with debian/package.templates.
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify postrm script.
=item B<--> I<params>
Pass the params to po2debconf, if it is run or debconf-mergetemplate, if it
is run.
