ecc4c5

4c79b5

4c79b5
        # portion of the path.  Sometimes, we call this common
4c79b5
        # portion of path the ``bond path''. This configuration is
4c79b5
        # strictly used under the following situations: 
4c79b5
        #
4c79b5
        #  1. There are too many translation files to apply to a
4c79b5
        #  single design template. This is the case of Brands
15b1d2
        #  artworks (see: trunk/Identity/Brands) rendition, where it
15b1d2
        #  is very difficult to maintain the relation list of design
15b1d2
        #  templates and translation files. E.g.:
4c79b5
        #
4c79b5
        #  bond/path/template.svg: \
ecc4c5
        #     bond/path/translation1.png.sh \
ecc4c5
        #     bond/path/translation2.png.sh
4c79b5
        #
4c79b5
        #  2. Translation files are under a directory with the same
4c79b5
        #  name of that used in the design template. All translation
4c79b5
        #  files inside this directory will be applied to the single
4c79b5
        #  design template that has the same name of the directory
4c79b5
        #  containing the translation files. E.g.:
4c79b5
        #
4c79b5

ecc4c5
