# Quick rundown:
# 
# This script bootstraps a FreeHL server complete
# with support for the following games:
# - Half-Life
# - Counter-Strike
# - Deathmatch Classic
# - Team Fortress
# - Half-Life: Opposing Force
# - Gunman Chronicles
# - Scientist Hunt (mod)
# - They Hunger (mod)
#
# You need to place the three files (unmodified) into
# the same directory as this script:
#
# hlserver4110.exe
# csv15full.exe (optional)
# opfor1108.tar.bz2 (optional)
# gunman_server.exe (optional)
# shunt12.exe (optional)
# TheyHunger3.exe (optional)
#
# Once you've done so, run this script and in the same
# directory the bootstrapping process will begin.
#
# You can run a server like this:
#
# ./fteqw-sv64 -halflife +sv_public 1 +set deathmatch 1 +set maxplayers 16 +map crossfire
# 
# A mod server looks like this:
#
# ./fteqw-sv64 -halflife -game cstrike +sv_public 1 +set deathmatch 1 +set maxplayers 16 +map de_dust2
#
# You'll probably want to specify other parameters, such as mp_timelimit etc.
# but you should probably put those into a server.cfg into their respective game
# directories. The server will execute files named `server.cfg` if present.
#
# This script should work on other operting systems, you only need to
# replace the fteqw-sv64 binary with one for your target platform/arch.
# The game-logic is entirely platform independent.
#
# Happy hosting!
