# FRENCH - POUR LES NULS
# Pour utiliser ce script il vous faut le language de programmation "python" installé sur votre machine (ce qui est d'origine si vous êtes sur MacOS ou un system Unix). Pour windows, il vous faudra l'installer (http://www.python.org/download), ensuite taper dans la console 'path=C:/Python__/' pour pouvoir utiliser directement python à partir de nimporte où.
# 
# Utilisation:
# Exporter une playlist d'iTunes en fichier .txt.
# copier coller le script (le fichier .py) dans le dossier ou se trouve votre playlist.
# Ensuite ouvez un terminal et aller dans ce dossier (le commande 'cd' pour change directory vous permet de naviguer dans les dossiers, 'ls' vous affiche le contenu du dossier courant et 'pwd' vous affiche votre emplacement).
# Taper 'python playlist_script.py <votre_fichier.txt>' sans les '<,>' dans le dossier.

• Backbone - Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface.
• AngularJS - Conventions based MVC framework for HTML5 apps.
• Underscore - Underscore is a utility-belt library for JavaScript that provides a lot of the functional programming support that you would expect in Prototype.js (or Ruby), but without extending any of the built-in JavaScript objects.
