)

var flags = struct {
    StringExample string `name:"string" shortname:"s" environment:"TEST_STRING" default:"Hello World" usage:"String Test"`
    IntExample    int    `name:"int"    shortname:"i" environment:"TEST_INT"    default:"8"           usage:"Int Test"`
    BoolExample   bool   `name:"bool"   shortname:"b" environment:"TEST_BOOL"   default:"true"        usage:"Bool Test"`
}{}

func main() {
    if err := flag.Parse(&flags); err != nil {
