# !!!! ATTENTION !!!!
# You are supposed to change at least the next 2 variables.
# Despite it's possible to leave username and passwort to $1 and $2, which 
# makes them command line parameters, it is strongly discouraged, as the
# password entered into your shell might be logged by some machanism equal
# or comparable to the .bash_history file. So please don't ;-)


# Change this to your mp3/4 player login/username
username="$1"
# Change this to your account password
password="$2"

# Change this to match your server password
# or leave it empty to generate a new randomized password for each gameserver
default_serverpassword=''
# Change this to the zone for your mp4 servers
default_serverzone='World|Europe|Germany|Hessen|Frankfurt'
server_prefix='paragonleague'
minid=1
