If present, a logging configuration will be read and applied from a file called 'logging.properties' in the application configuration directory ('.arbil'). An example of such a configuration is given below.

The logging output (visible in the log console of the Help menu) can be observed from different levels of detail. Such levels are: ALL, FINE, INFO, WARNING, SEVERE. Note that the log console is visible only when the application is installed, i.e. NOT with the webstart version.

        handlers= java.util.logging.FileHandler, java.util.logging.ConsoleHandler
        
        # Default global logging level.
        .level = ALL
