* Engine for the Handlebars template language. You will need `handlebars` Node
* module installed in order to use [[Mincer]] with `*.hbs` files:

* as well as standalone 'middleware' processor in a pipeline.
*
* **NOTICE** Generated functions require you to have `handlebars` client
* runtime to be required:
*
* ``` javascript
* //= require handlebars.runtime
* //= require templates/hello
* ```
*
*
