#############################################################################
# Script used to start Liquid War servers, and run them as UNIX daemons.
#
# Typically, you could place this file in /etc/init.d, so that servers
# are started automatically when you boot your computer.
#
# Keep in mind that Liquid War is a *game* so its code might not be
# 100% exploit proof, and anyway, since Liquid War comes with
# NO WARRANTY at all, you simply run it at your own risks.
# This is not to scare you, but rather to insist on the fact that
# you should never run Liquid War servers as root. Run it under a
# "basic" user, which has very few rights, since the only rights the
# Liquid War daemon needs are:
# - be able to bind on a socket > 1024
# - be able to append stuff to a log file
# - be able to write its pid in a file
# None of these requires to be logged as root, so don't do it.
#
# Also keep in mind that running this script with its default options
# will make the Liquid War server you run on your computer register
# itself on the meta-server on www.ufoot.org. So people will be aware
# that you have a Liquid War server on your machine. While this is good
# for people who try to automatically find other online fellows,
# you might find this behaviour somewhat intrusive. Change the $PRIVACY
# value if the default behaviour does not match your needs.
# Clear our environment so we don't leak.

# As start-stop-daemon seems to be a quite Debian-specific utility,

# edit the $START and $STOP commands to match your system.

# private -> the server does not register itself
# by default, it is public, but you might want to change this

# by default, it is set to "nobody:games", this assumes that

# need to either create a games group (and maybe a nobody user as weel)
# or change the $USER value, but remember: do *not* set it to root!
