# 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.
