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