Hi, a new section appeared in the central Debian translation statistics: http://www.debian.org/intl/l10n/po-debconf/ in order to help l10n of debconf templates when they are managed in source packages by po-debconf. As with other l10n repositories based on PO files, translators have to download the PO files for their language, fix missing and outdated translations (POT files are also available to start new translations), and send them to the package maintainer (via the BTS). There is no need for any external program, but please check (e.g. with msgfmt) that your files contain no errors before sending them.
These pages are updated daily. Denis
