     `goctl` 读作 `go control`，不要读成 `go C-T-L`。`goctl` 的意思是不要被代码控制，而是要去控制它。其中的 `go` 不是指 `golang`。在设计 `goctl` 之初，我就希望通过 `工具` 来解放我们的双手👈

    `goctl`can be read as `go control`. `goctl` means not to be controlled by code, instead, we control it. The inside `go` is not `golang`. At the very beginning, I was expecting it to help us improve productivity, and make our lives easier.
