+=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.
