Explained the structure of django.template.

"""

Django's support for templates.

The django.template namespace contains two independent subsystems:

1. Multiple Template Engines: support for pluggable template backends,

   built-in backends and backend-independent APIs

2. Django Template Langage: Django's own template engine, including its

   built-in loaders, context processors, tags and filters.

Ideally these subsystems would be implemented in distinct packages. However

keeping them together made the implementation of Multiple Template Engines

less disruptive .

Here's a breakdown of which modules belong to which subsystem.

Multiple Template Engines:

- django.template.backends.*

- django.template.loader

- django.template.response

Django Template Language:

- django.template.base

- django.template.context

- django.template.context_processors

- django.template.loaders.*

- django.template.debug

- django.template.defaultfilters

- django.template.defaulttags

- django.template.engine

- django.template.loader_tags

- django.template.smartif

Shared:

- django.template.utils
