4591de

4591de

4591de

4591de
        # these cases localized content are stored in the same
4591de

4591de
        # to avoid using localized content from being interpreted as
4591de
        # design models. In that sake, supress language-specific files
4591de
        # from the list of files to process.
294842
        #
4591de
        # Another issue to consider here, is the way of filtering. We
4591de

4591de
        # `.*' here (e.g., "${FLAG_FILTER}.*\.${RENDER_EXTENSION}")
4591de

4591de
