If no option is specified, the config file named\n        tslint.json is used, so long as it exists in the path.\n        The format of the file is { rules: { /* rules list */ } },\n        where /* rules list */ is a key: value comma-seperated list of\n        rulename: rule-options pairs. Rule-options can be either a\n        boolean true/false value denoting whether the rule is used or not,\n        or a list [boolean, ...] where the boolean provides the same role\n        as in the non-list case, and the rest of the list are options passed\n        to the rule that will determine what it checks for (such as number\n        of characters for the max-line-length rule, or what functions to ban\n        for the ban rule).\n\n    -i, --init:\n        Generates a tslint.json config file in the current working directory.\n\n    -o, --out:\n        A filename to output the results to. By default, tslint outputs to\n        stdout, which is usually the console where you're running it from.\n\n    -r, --rules-dir:\n        An additional rules directory, for additional user-created rules.\n        tslint will always check its default rules directory, in\n        node_modules/tslint/build/rules, before checking the user-provided\n        rules directory, so rules in the user-provided rules directory\n        with the same name as the base rules will not be loaded.\n\n    -s, --formatters-dir:\n        An additional formatters directory, for user-created formatters.\n        Formatters are files that will format the tslint output, before\n        writing it to stdout or the file passed in --out. The default\n        directory, node_modules/tslint/build/formatters, will always be\n        checked first, so user-created formatters with the same names\n        as the base formatters will not be loaded.\n\n    -t, --format:\n        The formatter to use to format the results of the linter before\n        outputting it to stdout or the file passed in --out. The core\n        formatters are prose (human readable), json (machine readable)\n        and verbose. prose is the default if this option is not used. Additonal\n        formatters can be added and used if the --formatters-dir option is set.\n\n    -v, --version:\n        The current version of tslint.\n\n    -h, --help:\n        Prints this help message.\n";
