Always show debug message until arguments are parsed.
    
    The application was failing when the configuration directory
    did not exist because this would try to show a debug message.
    However the debug function would only show them if the option
    was selected in CLI arguments and at this time, the options
    were not parsed and ready.
    
    Now, we always show debug messages before arguments are parsed
    and we stop showing them when the CLI argument is not used.
