Define flags using flag.String(), Bool(), Int(), etc.
This declares an integer flag, -flagname, stored in the pointer ip, with type *int.
This declares an integer flag, -n, stored in the pointer nFlag, with type *int:
import "flag"
var ip = flag.Int("flagname", 1234, "help message for flagname")

var flagvar int
func init() {
