=head1 SYNOPSIS

  dh_installdebconf [debhelper options] [-n]

=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.

=head1 LOCALIZED TEMPLATE FILES

Debconf also supports localized template files, and this program has some
support to aid working with them. You may find it easiest to keep the
translations in separate files, and merge them only at build time. See
L<debconf-mergetemplate(1)> and L<debconf-getlang(1)> for details.

This program will automatically call debconf-mergetemplate and merge 
templates on the fly if it finds your template files are accompanied
by translated files that have the same name as the template file, with a
dot and a locale name repended.

For example, if you have a German translation,
debian/package.templates.de is merged with debian/package.templates.
