    1.  If you want to use a custom Configurator,
        set the LOG4PHP_CONFIGURATOR_CLASS constants to Your Configurator class file.
        The class name must have the same base name of the classfile.

         Ex: define('LOG4PHP_CONFIGURATOR_CLASS', '/my/path/LoggerMyConfigurator');

          Log4php will try to include '/my/path/LoggerMyConfigurator.php'
          and instantiate a 'LoggerMyConfigurator' class.

    2.  If you want to use a configuration file that's not the default,
        set the LOG4PHP_CONFIGURATION constants to Your configuration filename.

        Ex: define('LOG4PHP_CONFIGURATION', '/my/path/my_config.conf');

        Note that if config extension is NOT .xml and LOG4PHP_CONFIGURATOR_CLASS
        is not defined, the LoggerPropertyConfigurator will be used.

    3.  If you want to bypass the initial configuration procedure, set the 
        'LOG4PHP_DEFAULT_INIT_OVERRIDE' to true.

         Ex: define('LOG4PHP_DEFAULT_INIT_OVERRIDE', true);
