# 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.
