"""
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 Language: 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
