Escaping curlies

What is the recommended way to escape curlies within a template so that they don't get interpolated?

For example:
```js
var template = "To access properties, surround the property with double curly braces (e.g.. {{foo}}).";
 
var result = markupJs.up(template, {});
// Desired output: -> `To access properties, surround the property with double curly braces (e.g.. {{foo}}).`
```
