# -u or --uninstall
# Functions :
# testing : Tests de connectivité et de téléchargement avant installation
# init : Installation des RPM et des scripts
# network : Paramètrage du réseau
# gestion : Installation de l'interface de gestion
# AC : Initialisation de l'autorité de certification. Création des certificats
# init_db : Création de la base 'radius' sur le serveur MySql
# param_radius : Configuration du serveur d'authentification FreeRadius
# param_web_radius: Configuration de l'interface de gestion de FreeRadius (dialupadmin)
# param_chilli : Configuration du daemon 'coova-chilli' et de la page d'authentification
# param_squid : Configuration du proxy squid en mode 'cache'
# param_dansguardian : Configuration de l'analyseur de contenu DansGuardian
# antivirus : Installation havp + libclamav
# param_awstats : Configuration de l'interface des statistiques de consultation WEB
