Help Request - Disable NAME and SYNOPSIS Output

I'm trying to find a way to disable the additional output that the fire library creates that comes after the process completes. It begins with NAME and includes SYNOPSIS. I have no need for this additional output in my scenario as it could potentially cause trouble for another external process that calls this and is examining the stdout for its own processing.

Here's an example of what I'm describing:
```
M:\Python\Workbench>FireHelpDocumentationExample.py --HowMuchPizza=1
()
NAME
FireHelpDocumentationExample.py --HowMuchPizza=1

SYNOPSIS
FireHelpDocumentationExample.py --HowMuchPizza=1 -
```

I would expect just:
`()`

An example of code I put together that was used to create this example [is here](https://gist.github.com/Sn3akyP3t3/f571c4baf272db191ed59f03359795c0).

重現 issue 中顯示的命令，並檢查 Python Fire 的說明輸出路徑，找出 NAME 和 SYNOPSIS 在哪裡輸出。確定應如何提供停用該輸出的方式，然後新增覆蓋，證明使用該選項時範例只會產生 `()`。
