# 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., "${FLAG_FILTER}.*\.${RENDER_EXTENSION}")
# because that would suppress any possibility from 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 filtering
# control to the user whom can use regular expression markup
# in the `--filter' option to decide whether to match
# `repository.docbook' only (e.g., through
# `--filter="repository"') or `repository-preamble.docbook'
# and `repository-parts.docbook' but not `repository.docbook'
# (e.g., through `--filter="repository-.*"').
