# Ce script permet la mise à jour ALCASAR 
#	- création de l'archive des fichiers de configuration (/tmp/alcasar-conf.tar.gz)
#	- chargement d'une archive (lors de la mise à jour d'un alcasar)
#	- application des directives du fichier de conf central "/usr/local/etc/alcasar.conf" (lors d'un changement de conf à chaud) 
# This script allows ALCASAR update 
#	- create the configuration files backup (/tmp/alcasar-conf.tar.gz)
#	- load the bachup of configuration files (during the update process)
#	- apply ALCASAR central configuration file "/usr/local/etc/alcasar.conf" (when hot modification are needed)
