        };
        
        // Create an option object with default value
        var opts = new Options(default_options);
        
        // Merge options
        opts = opts.merge(options);
        
        // Reset to default value
        opts.reset();
        
        // Copy selected attributes out
        var seled_att = opts.copy("foo");
        
        // Read json options from a file. 
        opts.read("options.file"); // Sync
        opts.read("options.file", function(err){ // Async
                if(err){ // If error occurs
                        console.log("File error.");
                }else{
                        // No error
                }
        });
        
        // Attributes defined or not
