Here is a full Hello world example

        public static void main(String[] args) {

            Hello hello = new Hello();

            CLISpecification cli = new CLISpecification(System.out);

            cli.add('n', "name", "Your name", CLIHandlers.string(hello.name));

            cli.add("prefix", "Prefix for your name, i. e. Mr, Mrs, Dr, Sir", CLIHandlers.string(hello.prefix));

            try {

                cli.run(args);

                application.run();

            } catch (CLIException ex) {

                System.out.println(ex.getMessage());

                System.out.println("usage: hello [OPTIONS]");

                try {

                    cli.usage();

                } catch (IOException ex1) {

                    ex1.printStackTrace(System.out);

                }

            } catch (IOException ex) {

                ex.printStackTrace(System.out);

            }

        }

        private Property name = new Property(null);

        private Property prefix = new Property("Mr.");

        private void run() {

            System.out.println("Hello " + prefix.get() + " " + name.get());

        }

    }

```

When you compile it and run like

    java -jar hello.jar -n John --prefix=Sir.

You'll get the following

    Hello Sir. John

You can get usage-message like this:

    java -jar hello.jar -h

You'll get the following answer

    Unknown option -h

    usage: hello [OPTIONS]

                     -n OPTION      Your name

                    --name=OPTION   Your name

                    --prefix=OPTION Prefix for your name, i. e. Mr, Mrs, Dr, Sir (default Mr.)
