# Insert of Oracle data into data files from mtg-data.txt
# Future possibilities. Using mtg-data to add SetInfo data and other Outside Game Data (Type, PT, etc)
# Hopefully the oracleScript can replace both SetInfo Scripts by current SetInfo scripts by expanding their current functionality

# python oracleScript.py <offlineMode> <setAbbreviation>
# If you run oracleScript without parameters it will run for all sets on the local mtgdata.txt
