pyramid_webassets 0.7.1

Configuration
====================
You are required to set base_dir and base_url, the rest are optional,
but we currently support:

* base_dir: The directory to output and search for assets
* base_url: The url static assets will be located
* debug: If webassets should be in debug mode (i.e no compression)
* updater: Different update configurations (i.e always, timestamp)
* cache: If we should use webassets cache
* jst_compiler: A custom jst compiler, by defalut it uses underscore

``` python
webassets.base_dir=%(here)s/app/static
webassets.base_url=/static
webassets.debug=True
webassets.updater=timestamp
webassets.cache=False
webassets.jst_compiler=Handlebars.compile
```

Then you can just use config.add_webasset to add bundles to your environment

``` python
jst = Bundle('templates/*.html',
filters='jst',
output='js/jst.js', debug=False)

config.add_webasset('jst', jst)
```

Mako
====================
You can use the global webassets tag:
``` python
% for url in webassets(request, 'css/bootstrap.css', 'css/bootstrap-responsive.css', output='css/generated.css', filters='cssmin'):
<link href="${url}" rel="stylesheet">
% endfor
```

or you can grab the environment from the request.

From The Request
====================
If you are not using Jinja2, you can still access the environment from the request.

```python
jst_urls = request.webassets_env['jst'].urls()
```


Jinja2
====================
If you are using Jinja2, you can just do the following configuration (this assumes use of pyramid_jinja2):

``` python
config.add_jinja2_extension('webassets.ext.jinja2.AssetsExtension')
assets_env = config.get_webassets_env()
jinja2_env.assets_environment = assets_env
```

Extras
====================
There are a few utility methods you can use:

get_webassets_env_from_settings(settings, prefix='static_assets'): Pass it a dictionary of your settings and an
optional keyword argument of the prefix in your configuration and it will return you a webassets environment.

get_webassets_env(request or config): This will pull the environment out of the registry, you can use either
a configurator object or a request.
