下图是用cli创建的示例程序gogo的帮助显示：
一个hello的例子
package main
import (
"github.com/mkideal/cli"
)
type argT struct {
Help bool `cli:"!h,help" usage:"display help information"`
Name string `cli:"name" usage:"your name" dft:"world"`
Age uint8 `cli:"a,age" usage:"your age" dft:"100"`
}
func main() {
cli.Run(&argT{}, func(ctx *cli.Context) error {
argv := ctx.Argv().(*argT)
if argv.Help {
ctx.String(ctx.Usage())
} else {
ctx.String("Hello, %s! Your age is %d?\n", argv.Name, argv.Age)
}
return nil
})
}
