# Greetings, fellow penguin!
|

#
|
||||
#
|
||||
# This script is designed to help you with some housekeeping tasks.
|
||||
#
|
||||
# It will check your system for optimal settings,
|
||||
# allowing you to change them as needed to prevent game crashes.
|
||||
#
|
||||
#
|
||||
# It also includes an easy way for you to wipe your USER folder
|
||||
# whenever there is a major version update. It will back up your
|
||||
# exported keybinds, delete your USER folder, then restore your keybinds.
|
||||
#
|
||||
# Edit the default paths below to match your configuration.
|
||||
#
|
||||
#
|
||||
# To export your keybinds from within the game, go to
|
||||
# Options->Keybindings->Control Profiles->Save Control Settings
|
||||
# Give it a name and save it in the backup location you specify below.
