render_getDirTemplate
# Define the list of files to process. Use an array variable to
# store the list of files to process. This make posible to realize
# verifications like: is the current base directory equal to the
# next one in the list of files to process? Questions like this
# is let us to know when centos-art.sh is leaving a directory
# structure and entering another. This information is required in
# order for centos-art.sh to know when to apply last-rendition
# actions.
#
# Another issue is that some directories might be named as if they
# were files (e.g., using a renderable extension like .docbook).
# In these situations we need to avoid such directories from being
# interpreted as a renderable file. For this, pass the
# `--type="f"' option when building the list of files to process
# in order to retrive regular files only.
#
# Another issue to consider here, is that in some cases both
# templates and outputs might be in the same location. In these
# cases localized content are stored in the same location where
# template files are retrived from and we need to avoid using
# localized content from being interpreted as design models. In
# that sake, supress language-specific files from the list of
# files to process.
#
# Another issue to consider here, is the way of filtering. We
# cannot expand the pattern specified by FLAG_FILTER with a `.*'
# here (e.g., "${FLAG_FILTER}.*\.${EXTENSION}") because tha would
# suppress any possibility of the user to specifiy just one file
# name in locations where more than one file with the same name as
# prefix exists (e.g., `repository.docbook',
# `repository-preamble.docbook' and `repository-parts.docbook').
# Instead, pass control of this to the user whom can use regular
# expression markup in the `--filter' option to decide whether to
# match `repository.docbook' (e.g., through
# `--filter="repository"') or both `repository-preamble.docbook'
# and `repository-parts.docbook' (e.g., through
# `--filter="repository.*"').
