How to get version of the program?

I can't find any command line argument to get help or version number of installed kminion instance.

I'm using something like that

```shell
$ strings /usr/local/bin/kminion | grep 'main.builtAt' | tail -1 | cut -d '=' -f 3 | cut -d ' ' -f 1
```

Could you please help me with a proper way? Thank you.
