# When running this updater, the following folder structure must
# exist directly below the updater's folder:
# OoliteRootFolder
# |
# --AddOns
# |   |
# |   --Basic-debug.oxp
# |--oolite.app
#
# Basic-debug.oxp should contain the Debug OXP files, while
# oolite.app should contain only the Test Release executable.
# The updater will pack everything it finds below the folder
# named OoliteRootFolder, so it is important that the folder
# structure be maintained.
