-- Anniversary Edition Setup v1.0
-- for Anniversary Edition Seven
-- by Iritscen
-- ***NOTE: Save as an application, then place Run AE Installer (built as an application too)
--      and AEsetuplogo.icns inside Contents/Resources/ folder of the Anniversary Edition Setup app.
--      Change the CFBundleIcon setting in the Setup app's Info.plist file to "AEsetuplogo" in order to
--      have the app use the icon.
-- For installing the Anniversary Edition Seven's AEI Updater. This script looks for an existing Oni
--      installation, places the AEInstaller2Updater into a new AE/ folder, and runs it. It also makes sure
--      that the user has Java installed so he can run the Updater and Installer.
