6
    Django context processor that applies all cloudbar settings in response
7
    context plus a ready to use pre rendered script html tag containing valid
8
    javascript code for cloudbar to display.

10
    To use it add ``synnefo.lib.context_processors.cloudbar`` in your project's
11
    ``TEMPLATE_CONTEXT_PROCESSORS setting`` (snf-webproject already does).

    Then in your base html template::

15
        <html>
16
        ....
17
        <head>
18
        ...

        {% if CLOUDBAR_ACTIVE %}
20
            {{ CLOUDBAR_CODE }}
21
        {% endif %}
