    This is a bit more complicated than for other packages.  The

    file for every language.  Those .tar.bz files are the kde-18n-<lang>
    files released by the KDE project.  For now, we only have the German
    localization in the enterprise source package, so the orig.tar.gz
    file will have the following contents:

      kde-l10n-<version>/
      kde-l10n-<version>/kde-l10n-de-<version>.tar.bz2

    <version> is the same everywhere.
