 =head1 LOCALIZED TEMPLATE FILES
 
 Debconf also supports localized template files, and this program has some
-support to aid working with them. It is best 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.
+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 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 prepended.
+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,
-debian/package.templates.de is merged with debian/package.templates.
+strings from debian/po/de.po are merged with debian/package.templates.
