# render_getDirTemplate.sh -- This function defines the way renderable
# directories are processed inside the repository.  Inside the
# repository, renderable directories are processed either through
# general-purpose rendition or theme-specific rendition.
#
# General-purpose rendition:
#
# The general-purpose 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:
#
# The theme-specific rendition takes one design model from
# `trunk/Identity/Models/Themes' directory structure to produce
# one or more images in
# `trunk/Identity/Motifs/$THEME/$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 general-purpose
# 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.
