#==============================================================================
#
# Changelog:
#
# 2014.10.19 - v1.00
#
# * Initial release
#
#==============================================================================
#
# To put it simple, I needed a script that allowed me to store my data locally,
# in case I wanted to make a sequel to a game and wanted to import data from
# said game. After some research I found out that most people are kind of dicks
# and require some form of permission, so I made my own.
#
#==============================================================================
#
# Installation:
#
# Make sure to put this below Materials, but above Main Process.
#
# This script adds aliases for several methods. If you are sure no method that
# is used by other scripts get overridden, you can place it anywhere,
# otherwise, make sure this script is loaded after any other script overriding
# these methods, otherwise this script stops working.
#
#------------------------------------------------------------------------------
# Aliased methods:
#
# * module DataManager
#   - save_file_exists?
#   - make_filename(index)
#
#==============================================================================
#
# Usage:
#
# This is quite literally plug-and-play. The only thing I want to say is that
# the save files are located inside the appdata folder.

# used by everyone without restriction. This ensures that people don't feel
# obligated to add a license notice or credits whenever the script is being
# used.
#
# Additional reasoning:
#
# This script was literally done in an hour, two hours if you include
# research and browsing reddit. To put it bluntly, it's insulting to put any
# form of limitations on this script or anything similar.
