## Usage

### CLI

$ sirenlint <siren-file>
```

_or_

```
$ cat <siren-file> | sirenlint
```

#### Example

```
$ echo '{ "links": [ { "rel": ["edit"] } ] }' | sirenlint

var fs = require('fs');
var path = require('path');
var validate = require('sirenlint');

var FILENAME = path.join(__dirname, '..', 'example', 'test.json');

var subject = fs.readFileSync(FILENAME);

var results = validate(subject);

results.forEach(function(r) {
  if (r instanceof validate.ValidationWarning) {
    console.log('WARNING:', r);
  } else if (r instanceof validate.ValidationError) {
    console.log('ERROR:', r);
