# Define the list of files to process. Use an array variable
# to store the list of files to process. This make possible to
# realize verifications like: is the current base directory
# equal to the next one in the list of files to process?
# Questions like this 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 render able extension like
# .docbook). In these situations we need to avoid such
# directories from being interpreted as a render able file.
# For this, pass the `--type="f"' option when building the
# list of files to process in order to retrieve 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 retrieved from and we need
# to avoid using localized content from being interpreted as
# design models. In that sake, build the list of files to
# process using the files directly stored in the directory
# passed as argument to centos-art.sh command-line. Don't go
# recursively here.
#
# Another issue to consider here, is the way of restricting
# the list of files to process. 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 specify 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-.*"').
