I know `eslint` CLI itself has a `--fix` flag, but I can't tell from the documentation how to use this via `eslintConfig` (in `package.json`) or in the grunt-eslint configuration in my Gruntfile.

I have the following config in `package.json`:

```
"env": {
  "browser": true,
  "amd": true
},
"extends": "eslint:recommended",

```

and invoke it via a `lint` task using this Grunt config:

```
    eslint: {
        target: [
            'src/app/**/*.js'
        ],
        format: 'checkstyle'
    },

```

How can I enable the `--fix` flag in this scenario?
