How to define Assetic resources in Symfony 2 yml or xml configuration file?

Can you define assetic resource in configuration file (yml/xml)?

Lets take jquery as example. I would like to have configuration like this:

# app/config/config.yml
assetic:
  resources:
     jquery: 
        latest: "app/Resources/js/jquery-1.6.2.js"
        1_6_2: "app/Resources/js/jquery-1.6.2.js"
        1_5: "app/Resources/js/jquery-1.5.js"

And to be able to access this resource from any template in my application something like this:

{% javascripts 'jquery.latest' %}
<script type="text/javascript" src="{{ asset_url }}"><开发者_如何学编程;/script>
{% endjavascripts %}

What is a proper way to do this?

And another thing. How do I reference path app/Resources/js/jquery-1.6.2.js in twig template?

{% javascripts 'app/Resources/js/jquery-1.6.2.js' %}
<script type="text/javascript" src="{{ asset_url }}"></script>
{% endjavascripts %}

This does not work. Can you do this at all? What resources I can place in app/Resources and how do I access them in my templates? Where it is documented?

Right now Symfony 2 is really lacking in documentation...

The path to define resources in your app/Resources folder must defined with a trailing: "../"

{% javascripts 
  "../app/Resources/js/qtip.jquery.js"
  "../app/Resources/js/layout.js"
  "@HomeBundle/Resources/js/*"  
%}

Not entirely sure how to help you on your first question, though, but hopefully this can help.

I think you want something along the lines of

{% javascripts '@NameOfYourBundle/path/from/bundle/root/to/jquery-1.6.2.js' %}
