=========

Synnefo web project

===================

A synnefo helper package to ease up the deployment of synnefo components.

The package wraps a django project which extends itself (urls, default_settings, 

installed_apps, middleware_classes) based on the synnefo components/packages 

installed on the system.

The extending mechanism is based on the python setuptools `entry_points`. So

if an application (synnefo component) wants to plug additional configuration

to the django project it should define within its setup.py file the 'synnefo'

appropriate entry_points.

For usage example please take a look how snf-app package defines its entry

points in:

    - snf-app/setup.py

    - snf-app/app_settings/__init__.py

#!python

"""Bootstrap distribute installation

If you want to use setuptools in your package's setup.py, just include this

file in the same directory with it, and add this to the top of your setup.py::

    from distribute_setup import use_setuptools

    use_setuptools()

If you want to require a specific version of setuptools, set a download

mirror, or use an alternate download directory, you can do so by supplying

the appropriate options to ``use_setuptools()``.

This file can also be run as a script to install or upgrade setuptools.
