Django datas dump script writer

Produce command line script usable within a Makefile or as a simple shell script to dump or load data with Django from the many app name you give it.

It need a dependancies map to know what is required to be dumped, actually this is only for "emencia-paste-djangocms-2" or "emencia-paste-djangocms-3" projects so it only knows about:

* Django contrib auth;
* Django sites;
* emencia.django.countries;
* contact_form;
* DjangoCMS and its common plugins;
* Zinnia;
* Porticus;
* South;
* django-tagging;
* django-taggit;
* easy-thumbnails;
* django-filer;
* django-google-tools;
* emencia-django-socialaggregator;
* emencia-django-slideshows;

Note : Many app depends on Django's content types but we don't matter because it is automatically filled by Django and we should never try to dump/load it.

	Django datas dump script writer

	Produce command line script usable within a Makefile or as a simple shell script to dump or load data with Django from the many app name you give it.

	It need a dependancies map to know what is required to be dumped, actually this is only for "emencia-paste-djangocms-2" or "emencia-paste-djangocms-3" projects so it only knows about:

	* Django contrib auth;
	* Django sites;
	* emencia.django.countries;
	* contact_form;
	* DjangoCMS and its common plugins;
	* Zinnia;
	* Porticus;
	* South;
	* django-tagging;
	* django-taggit;
	* easy-thumbnails;
	* django-filer;
	* django-google-tools;
	* emencia-django-socialaggregator;
	* emencia-django-slideshows;

	Note : Many app depends on Django's content types but we don't matter because it is automatically filled by Django and we should never try to dump/load it.
