ifnav-Tag for Django Templates
==============================

The ifnav-Tag is used to match the current request path against
a regular expression.

Example:

    {% load ifnav %}
    <ul>
        <li{% ifnav "^/foo/" %} class="selected"{% endifnav %}
                <a href="/foo/">Foo</a></li>
        <li{% ifnav "^/bar/" %} class="selected"{% endifnav %}
                <a href="/bar/">Bar</a></li>
    </ul>

This tag is meant for rather simple and static navigations.

In order to use this tag you have to enable the request context
processor, which comes with django, but is disabled by default:

http://docs.djangoproject.com/en/dev/ref/templates/api/#django-core-context-processors-request

Alternatively you can also set the request object in the template
context directly.
