-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.
