""" Plugin pour bcfg2 pour générer des fichiers de conf en prenant la sortie d'un
script python.
Ce plugin est une extension du plugin Python rajoutant des informations sur la configuration de bcfg2.
Les scripts python de génération de conf utilisant ce plugin peuvent par exemple lister les noms des clients
appartenant à un groupe donné. C'est très pratique pour générer la conf de clients qui ont un rôle de serveur
pour tous les autres clients en différenciant suivant leurs rôles.
Exemples : serveur de sauvegarde, monitoring.
