# Remember to start the teamspeak server manually the first time so you get the
# server admin password and the server admin token.
# If you want to use mysql database, remember to create a ts3db_mysql.ini file
# in the folder ts3 in installed in. And make sure ts3server.ini is set right.
# Changelog @ http://forum.teamspeak.com/showthread.php?t=46989
#
# The test start option will check if you are missing anything before you start the script
