# Script d'installation d'ALCASAR (Application Libre pour le Contrôle d'Accès Sécurisé et Authentifié au Réseau)
# ALCASAR est architecturé autour d'une distribution Linux Mageia minimaliste et les logiciels libres suivants :
# Install script for ALCASAR (a secured and authenticated Internet access control captive portal)
# ALCASAR is based on a stripped Mageia (LSB) with the following open source softwares :

# Coovachilli, freeradius, mariaDB, lighttpd, netfilter, e2guardian, ntpd, openssl, dnsmasq, gammu, havp, libclamav, Ulog, fail2ban, tinyproxy, NFsen and NFdump

# Options :
#       -i or --install
#       -u or --uninstall

# Functions :
#       testing                 : connectivity tests, free space test and mageia version test
#       init                    : Installation of RPM and scripts
#       network                 : Network parameters
