# Define action name. It does matter what option be passed to
# centos-art, there are many different actions to perform based on
# the option passed (e.g., `--packages', `--links',
# `--environment', etc.). In that sake, we defined action name
# inside prepare_getOptions, at the moment of interpreting
# options.
# Define action value. There is no action value in this function,
# but action name values only. There is no need for non-option
# arguments here since we are doing fixed verifications only in
# predifined paths.
# Verify flags and execute actions accordingly. Start with
# packages, links and then environment.
