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

var flagvar int
func init() {

Flags may then be used directly. If you're using the flags themselves,
they are all pointers; if you bind to variables, they're values.
fmt.Println("ip has value ", *ip);
fmt.Println("flagvar has value ", flagvar);
fmt.Println("ip has value ", *ip)
fmt.Println("flagvar has value ", flagvar)
After parsing, the arguments after the flag are available as the
slice flag.Args() or individually as flag.Arg(i).
