#
# Script to export the scripts inside the Scripts.rvdata2 data file to Data/exported_scripts as plain text Ruby files.
# If you run this script from inside RPG Maker VX Ace, I would suggest creating the Data/exported_scripts folder yourself
# as RGSS3 doesn't seem to support requiring FileUtils.
# Based on HIRATA Yasuyuki / 平田 泰行's rvdata2_dump.rb script: https://gist.github.com/hirataya/1853033
