# Source code for django.template.context_processors

    """
    A set of request processors that return dictionaries to be merged into a
    template context. Each function takes the request object as its only parameter
    and returns a dictionary to add to the context.

    These are referenced from the 'context_processors' option of the configuration
    of a DjangoTemplates backend and used by RequestContext.
