#
# Explanation:
#   Simple script for creating backups of your game each time the game is ran
#   in debug mode. Its runs very quickly and there is practically no slowdown,
#   even with large games.
#
# Features:
#   - Backups your Data folder automatically each debug run
#   - Configurable number of backups
#   - Runs on a separate thread and invokes system functions for the actual
#     processing to prevent any slowdown
#
# Instructions:
#   - Place script anywhere above "Main"
#   - Configure the number of backups you would like to keep.
#   - Backups will be stored in the "Backups" folder in the main game directory,
#     and are always listed in order of newest to oldest
#
# Credit/Thanks:
#   - ForeverZer0, for the script
#
# Authors Notes:
#   - Please report any bugs issues at www.chaos-project.com
