+# Daemon qui recupère les sms de rabbitmq et les envoie via gammu sur zamok
+# Il récupère les sms en tant que user sms et dans la queue SMS
+# Largement repris de crans ticket
+# Les autres scripts n'ont plus qu'a peupler la file d'attente avec 
+# des dicts (numero de tel, contenu du msg)
+
+# Un service gammu tourne sur zamok, ainsi qu'un service cranssms qui appelle daemon
