        This is the config for PHP Code Sniffer.

        Here you can look at all available sniffs,
        sure you'll be able to figure out how classes and their parameters
        correspond to this config:
        http://pear.php.net/package/PHP_CodeSniffer/docs/latest/li_PHP_CodeSniffer.html

        YiiBoilerplate initially expects you to follow it's own coding standard,
        which differs from any common standards like PEAR, Zend or PSR.
        It's because we are using something like Yii coding standard
        but without some of it's insanity like mandatory braces (even in one-liner ifs)
        and mandatory leading underscores in private members.

        Of course, you can adapt this ruleset to anything you like.
