// 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) {
|
|
// println("Greetings")
|
|
// }
|
|
//
|
|
// app.Run(os.Args)
|
|
// }
