name: require
parameters:
  - path

`require(...)` behaves similarly to its equivalent in node.js. You can use it
to split your configuration across multiple files. If the path starts with a
`.`, it is calculated relative to the current file. For example:

{% include startExample.html %}
{% highlight js %}

// dnsconfig.js
require('kubernetes/clusters.js');

D("mydomain.net", REG, PROVIDER,
    IncludeKubernetes()
);

{%endhighlight%}

{% highlight js %}

// kubernetes/clusters.js
require('./clusters/prod.js');
require('./clusters/dev.js');

function IncludeKubernetes() {
    return [includeK8Sprod(), includeK8Sdev()];
}

{%endhighlight%}

{% highlight js %}

// kubernetes/clusters/prod.js
function includeK8Sprod() {
    return [ /* ... */ ];
}

{%endhighlight%}

{% highlight js %}

// kubernetes/clusters/dev.js
function includeK8Sdev() {
    return [ /* ... */ ];
}

{%endhighlight%}
{% include endExample.html %}

You can also use it to require json files and initialize variables with it:
For Example:

{% include startExample.html %}
{% highlight js %}

// dnsconfig.js
var domains = require('./domain-ip-map.json')

for (var domain in domains) {
    D(domain, REG, PROVIDER,
        A("@", domains[domain])
    );
}

{%endhighlight%}

{%highlight js %}
// domain-ip-map.json
{
    "mydomain.net": "1.1.1.1",
    "myotherdomain.org": "5.5.5.5"
}
{%endhighlight}
{% include endExample.html %}
