## How to scan source code and generate xmake.lua automaticlly

You only need run the following command:

```bash
$ xmake
```

xmake will scan all source code in current directory and build it automaticlly. 

And we can run it directly.

```bash
$ xmake run
```

If we only want to generate xmake.lua file, we can run:

```bash
$ xmake f -y
```
