#
# ===========================================
#
# What you need:
#
# Linux :)
# awk
# screen
# the srcds_l & cstrike files (obtainable via steam)
#
# How to use:
#
# Edit the CS_USER-Var to the user running your cs-servers
# Edit the DIR-Var to fit your system (just contains the path to the dir that contains srcds_run)
# Edit the PARAMS-Var to fit your needs
# - standard is startup as internet server
# if you use multiple scripts on one system you should change the NAME-var (otherwise 
# all will be stopped if you run the script with "stop", and status will be useless)
#
# When this is done, copy the file to /etc/rc.d/init.d (or whereever your system stores the
# scripts for starting the services) and set the execute permission.
# Now you can link the script to your runlevel-dir, here's an example for runlevel 3:
# ln -s /etc/rc.d/init.d/srcds /etc/rc.d/rc3.d/S90srcds
# ln -s /etc/rc.d/init.d/srcds /etc/rc.d/rc3.d/K50srcds
# or use update-rc.d if you got a system using that tool (like Debian, see manpage)
#
# Or use it manually like:
# ./srcds start
# ./srcds stop
#
# To see the server-console start the script with the parameter "watch".
#
# DOC by jwm (jwm@counter-strike.de)

# !!!!!!!!!!!!!! CHANGE THIS TO THE USER YOU USE FOR YOUR SERVER !!!!!!!!!!!!!!!
