 the most simple cli application can be written as follows:
 
     func main() {
-    	(&cli.App{}).Run(os.Args)
+      (&cli.App{}).Run(os.Args)
     }
 
 Of course this application does not do much, so let's make this an actual
 application:
 
-    func main() {
-    	app := &cli.App{
-      		Name: "greet",
-      		Usage: "say a greeting",
-      		Action: func(c *cli.Context) error {
-      			fmt.Println("Greetings")
-      			return nil
-      		},
-    	}
-
-    	app.Run(os.Args)
-    }
+      func main() {
+        app := &cli.App{
+    			 Name: "greet",
+    			 Usage: "say a greeting",
+    			 Action: func(c *cli.Context) error {
+    				 fmt.Println("Greetings")
+    				 return nil
+    			 },
+    		 }
+
+        app.Run(os.Args)
+      }
