+// Package cli provides a minimal framework for creating and organizing command line
+// Go applications. cli is designed to be easy to understand and write, the most simple
+// cli application can be written as follows:
+//
+//	func main() {
+//		(&cli.Command{}).Run(context.Background(), os.Args)
+//	}
+//
+// Of course this application does not do much, so let's make this an actual application:
+//
+//	func main() {
+//		cmd := &cli.Command{
+//	  		Name: "greet",
+//	  		Usage: "say a greeting",
+//	  		Action: func(c *cli.Context) error {
+//	  			fmt.Println("Greetings")
+//	  			return nil
+//	  		},
+//		}
+//
+//		cmd.Run(context.Background(), os.Args)
