    # 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.
