# action plan for final product:
# 1) Get a list of mod jars from a directory
# 2) Install appropriate version of minecraft if it is not already installed
# 3) Install appropriate version of minecraft forge if it is not already installed
# 4) Launch empty version of minecraft forge to generate boilerplate file structure
# 5) Exit the process after it launches successfully
# 6) For each Jar:
#   a) Copy jar to directory
#   b) Attempt to launch the game
#   c) Record whether or not the game successfully launched/built/etc
#   d) If the game failed to launch, mark the jar as disabled
#   e) Continue to next jar
