  -->  This version comes with a system init script now. You have to run the
  -->  "firestarter" executable from the command line (in an X driven console)
  -->  first to generate the initial start-up scripts.
  -->  If you'd like firestarter brought up on system initialization, add
  -->  firestarter to the DAEMONS line of your /etc/rc.conf (after network)
  -->  Consider to use gksu to start firestarter, since firestarter has to be
  -->  used as root to change the settings of you firewall. It is called as
  -->    "gksu firestarter"
  -->  and brings it's own menu entry if gksu is installed on the system.
  
  -->  Some autodetection for the messages logfile has been included, the
  -->  original code looks for /var/log/kernel and /var/log/messages. In this
  -->  package detection for /var/log/messages.log and /var/log/kernel.log
  -->  has been added. So metalog, sysklogd and syslog-ng users should be happy,
  -->  as long as you remove unused log files form the directory.
