############################# START CONFIGURATION ############################
 
# This is a configuration notecard based on the key-value data Wizardry and Steamworks reader. 
# Everything following the "#" character is ignored along with blank lines. Values can be set for various 
# parameters in a simple and understandable format with the following syntax: 
# KEY = "VALUE" 
# Every time you change this configuration notecard, the script will reset itself and the new configuration 
# will be read from this notecard.
 
# The "corrade", "group" and "password" settings must correspond to your settings in Corrade.ini
 
# This is the UUID of the Corrade bot.
corrade = "1272a407-1af3-47f7-abcd-79f81d28637d"
 
# The name of the group - it can also be the UUID of the group.
group = "My Group"
 
# The password for the group.
password = "mypassword"
 
# This represents the scan interval to detect avatars. Note that this script does not rescan avatars.
interval = "10"
 
# This represents the amount of free memory measured in bytes that the script will attempt to maintain. 
# After the memory usage of this script exceeds this amount, the script will start culling the list of 
# detected avatars in an attempt to not overflow and keep the script running.
memory = "1024"
