# alcasar-conf.sh
# by REXY
# This script is distributed under the Gnu General Public License (GPL)

# Ce script permet de mettre à jour d'ALCASAR
#       - création de l'archive des fichiers de configuration "/var/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). Le cas échéant, c'est ici qu'on met à jour les fichiers entre versions
#       - application des directives du fichier de conf central "/usr/local/etc/alcasar.conf" à chaud (alcasar-conf -apply)
# This script allows ALCASAR update
#       - create the configuration files backup "/var/tmp/alcasar-conf.tar.gz" (alcasar-conf.sh -create)
#       - load the backup of configuration files during the update process (alcasar-conf -load). If needed, it's here we update files between versions
#       - apply ALCASAR central configuration file "/usr/local/etc/alcasar.conf" when hot modification are needed (alcasar-conf -apply)
