"""
    Une documentation de ce fabfile s'impose.

    fabric est une solution de deploiment
    -> http://docs.fabfile.org/0.9.0/

    ce fichier définit des rules pour:

    -> restarter les services (nginx, gunicorn, memcached)
    -> mettre a jour le code (via mercurial)

    chaque path est configurable via le fichier conf.yaml.

    notez que:
        - c'est super dépendant du path et du repository qui sont 
        toujours organisés de la sorte chez moi:

        repos/
            src/
                <project_django>/   # le dossier du projet django
            sandbox/                # le virtualenv
            deploy/                 # le dossier ou se trouve le fabfile
            doc/                    # ce dossier est voué a etre vide

    généralement, il me suffit de faire:
    fab {pre,}prod install

    todo: 
        - ajouter south

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
Tip: Use ↑ and ↓ arrow keys to navigate and return to view the file.
Tip: You can also navigate files with Ctrl+j (next) and Ctrl+k (previous) and view the file with Ctrl+o.
Tip: You can also navigate files with Alt+j (next) and Alt+k (previous) and view the file with Alt+o.
