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.
