### MAKE MAC APP
# OPTIONS
#   Packr   -> multiple platforms, siging instructions
#   jar2app -> 
#   javapackager

# 3 things we want customized
# - title in top bar of the window (done in engine.GameContainer)
# from here: http://www.oracle.com/technetwork/articles/java/javatomac-140486.html
# - App name in menu bar (use -Xdock:name="" when running java)
# - App name in dock...doesn't change though

# - App icon in the dock: -Xdock:icon="path/to/file.icns"
#   Otherwise change the info.plist from the applescript


# --vmargs Xmx1G XstartOnFirstThread \
# --useZgcIfSupportedOs \
