    # centos-art.sh script. For example, if you execute the following
    # command:
    #
    #   centos-art locale Documentation/Models/Svg/Brands --update
    #
    # it should produce the following directory structure:
    #
    #   Locales/Documentation/Models/Svg/Brands/Logos/${LANG}/
    #   Locales/Documentation/Models/Svg/Brands/Symbols/${LANG}/
    #   Locales/Documentation/Models/Svg/Brands/Types/${LANG}/

    #
    #   Locales/Documentation/Models/Svg/Brands/${LANG}/

    # here. Instead, do it just before POT files creation.

    # extract translatable strings from XML-based files or to use
