# Introduction:
# This is a very basic script I wrote to help myself split up one of them big
# icon sheets into individual files. After admiring its niftiness for a sec, I
# realized someone else may get some use out of it as well, so here it is.
#
# Features:
# - Extremely simple to use.
# - Splits large icon/sprite sheets up into uniform images, then saves them as
# individual files in a matter of seconds.
# - Can seperate any image into pieces of any size.
# - Combines many images of any size into one single file
# - Lightweight and fast
#
# Instructions:
# - Place script in new project or temporarily in an existing game anywhere
# before "Main"
# - Make any needed changes to the few configurations at the top of the script
# - Run the game
#
# Credits:
# - ForeverZer0, for the script
#
# Author's Notes:
# - Report bugs/issues at [url=http://www.chaos-project.com]www.chaos-project.com[/url]
