# Create a template and translation matching list. With this
# configuration we can optimize the rendition process for
# artworks like Anaconda progress slides and installation
# media, where many translation files apply one unique design
# template file.
#
# Previous to this feature, there was one (repeated) design
# template for each design holding the same design in all
# cases, basically a raw copy. This structure is very hard to
# maintain so it was reduced and optimized as we described
# above.
#
# The idea is to create a link and customizable relation
# between translation files and design template files in
# pre-rendition configuration scripts and then interpret it
# here.
#
# This way we pretend to eliminate duplicated design templates
# saying something like translation 1.png.sh, 2.png.sh,
# 3.png.sh, 4.png.sh, and 5.png.sh apply to the single design
# template A.svg. Or, 1.png.sh, 3.png.sh, 4.png.sh to A.svg
# and 2.png.sh and 5.png.sh to B.svg.
#
# Possible configuration 1: In this first case,
# translation files and design templates share a common
# portion of the path. Sometimes, we call this common
# portion of path the ``bond path''. This configuration is
# strictly used under the following situations:
#
# 1. There are too many translation files to apply to a
# single design template. This is the case of Brands
# artworks (see: trunk/Identity/Brands) rendition, where it
# is very difficult to maintain the relation list of design
# templates and translation files. E.g.:
#
# bond/path/template.svg: \
# bond/path/translation1.png.sh \
# bond/path/translation2.png.sh
#
# 2. Translation files are under a directory with the same
# name of that used in the design template. All translation
# files inside this directory will be applied to the single
# design template that has the same name of the directory
# containing the translation files. E.g.:
#
# bond/path/green.svg: \
# bond/path/green/translation1.png.sh \
# bond/path/green/translation2.png.sh
#
BOND=$(echo $TRANSLATION \
| sed -r "s/^.*\/$PARENTDIR\/(.+)\/.*\.${EXTENSION}$/\1/")
# If there is no template at this point, start reducing the
# bond path and try to use the result as template. This is
# needed in those cases where you have a directory structure
# with various levels of translations inside it and want to
# apply the last available design template that match to all
# translation files in the directory structure.

done
fi
# Possible configuration 2: If no template is found using the
# previous bond paths reduction, then lets look using design
# template and translation file base name bond only. Use this
# configuration as much as possible. Note that it is much
# more flexible than possible configuration 1.
#
# In this configuration, the pre-rendition configuration takes
# the following form:
#
# template.svg: \
# translation1.png.sh \
# translation2.png.sh

# Possible configuration 2.1: If not design template was found

# files that doesn't use an extension (e.g., see inside
# `trunk/Identity/Release' directory structure).

# to many differnt design templates at the same time. This
