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

    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
