This prevents nasty path resolving bugs (for a motivating example, have a look at [this redux issue](https://github.com/reactjs/redux/issues/1681)).

 #### Quiet Mode
-If you want to mute console output apart from errors, set `--quiet` (`-q`) or `validate(config, yourSchema, {quiet: true})`. This is particularly useful if you are using webpack `--json` as you'll want to avoid writing additional text to the JSON output.

+#### Validate all **package.json** `scripts`
 It is possible to use the CLI to validate all your **package.json** `scripts` related configurations at once by using `--all-scripts` (`-a`). The system will try to guess the convention you are using and then executes validation against each script target based on that.
 
 #### Advanced Usage
-If you need to access the validation results directly and want to control the side-effects (i.e. console.log output, `process.exit(1)` on fail behaviour) yourself, you can call the validation function like so: `validate(config, yourSchema, { returnValidation: true })`. This will make 1) the function return the validation results instead of your configuration and 2) not perform any side effects.

 #### Support
 Because this module uses the amazing `Joi` validation library, this module only supports Node >=4.0.0.
