> Crawls a given site and checks for W3C validity.

## Installation

```BASH
$ npm install -g w3c-validator-cli
```

## Usage
```BASH
$ w3c-validator [options] <url>
```

The crawler will fetch all sites matching folder URLs and certain file extensions.

**Tip**: Omit the URL protocol, the crawler will detect the right one.

**Important**: Executing the w3c-validator with sites using HTML `base`-tag along with links *without* leading slashes will probably not work.

## Options
```BASH
$ w3c-validator --help

  Usage: w3c-validator [options] <url>

  Options:

    -h, --help      output usage information
    -V, --version   output the version number
    -l, --log       log errors in a text file
    -q, --query     consider query string
    -v, --verbose   show error details
```


### log

### query

Consider URLs with query strings like `http://www.example.com/?foo=bar` as indiviual sites and add them to the sitemap.

### verbose

Output additional error information in the console.
