=head1 NAME
dh_installdebconf - install files used by debconf in package build directories
=cut
use strict;

=head1 SYNOPSIS
B<dh_installdebconf> [S<I<debhelper options>>] [B<-n>] [S<B<--> I<params>>]
=head1 DESCRIPTION
B<dh_installdebconf> is a debhelper program that is responsible for installing
files used by debconf into package build directories.
It also automatically generates the F<postrm> commands needed to interface
with debconf. The commands are added to the maintainer scripts by
B<dh_installdeb>. See L<dh_installdeb(1)> for an explanation of how that
works.
Note that if you use debconf, your package probably needs to depend on it
(it will be added to B<${misc:Depends}> by this program).
Note that for your config script to be called by B<dpkg>, your F<postinst>
needs to source debconf's confmodule. B<dh_installdebconf> does not
install this statement into the F<postinst> automatically as it is too
hard to do it right.
=head1 FILES
=over 4
=item debian/I<package>.config
This is the debconf F<config> script, and is installed into the F<DEBIAN>
directory in the package build directory.
Inside the script, the token B<#DEBHELPER#> is replaced with
shell script snippets generated by other debhelper commands.
=item debian/I<package>.templates
This is the debconf F<templates> file, and is installed into the F<DEBIAN>
directory in the package build directory.
=item F<debian/po/>
If this directory is present, this program will automatically use
L<po2debconf(1)> to generate merged templates
files that include the translations from there.
For this to work, your package should build-depend on F<po-debconf>.
=back
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify F<postrm> script.
=item B<--> I<params>
Pass the params to B<po2debconf>.
