// 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.NewApp().Run(os.Args)// }//// Of course this application does not do much, so let's make this an actual application:// func main() {// app := cli.NewApp()// app.Name = "greet"// app.Usage = "say a greeting"// app.Action = func(c *cli.Context) error {// println("Greetings")// return nil// }//// app.Run(os.Args)// }packagecli//go:generate python ./generate-flag-types cli -i flag-types.json -o flag_generated.go
