############################################# PARAMETERS & SERVER.CFG ###############################################
#
# SVNUM will come in handy for when you're hosting multiple Servers on the same Dedicated Machine.
# Replace "1.3.3.7" with your Dedicated's Server IP.
# Replace 27015 with the Port this L4D2 Server will be hosted on.
#
# Rename your Server.cfg files accordingly, if you're hosting just one server, you'll only need server1.cfg
# If you're hosting multiple Servers, simply copy server1.cfg, change the hostname inside and rename it to server2.cfg and so on.
# Don't forget to copy and edit the file as well, the SVNUM has to match the server#.cfg and the Port has to be available.
