# render_getDirTemplate.sh -- This function defines the way renderable
# directories are processed inside the repository.  Inside the
# repository, renderable directories are processed either through
# direct or theme-specific rendition.
#
# Direct rendition takes one XML file from design model
# (`trunk/Identity/Models') directory structure and produces one file
# in `trunk/Identity/Images' directory strucutre. In this
# configuration, the organization used to stored the design model is
# taken as reference to build the path required to store the image
# related to it under `trunk/Identity/Images' directory structure. 
#
# Theme-specific rendition takes one design model from
# `trunk/Identity/Models/Themes' directory structure to produce one or
# more images in `trunk/Identity/Images/Themes/$THEME/$VERSION/$MODEL'
# directory structure. In this configuration we have many different
# artistic motifs that use one unique design model directory structure
# as reference to produce images. 
#
# Since theme design models are unified to be reused by more
# than one artistic motif, it is not possible to render artistic
# motifs in a lineal manner (i.e., as we do with direct rendition)
# because we need to establish the relation between the artistic motif
# renderable directory structure and the design model first and that
# relation happens when renderable directory structures inside
# artistic motifs are processed individually.
#
# In the first rendition category, we use a design model directory
# structure as reference to produce images one by one. In the second
# rendition category, we can't use the same procedure because one
# design model directory structure is used to produce several
# renderable directory structures, not just one.
