title: Add a python flag cx_freeze to executable
body: <p>I'm making a game using pyglet, which runs like a tortoise (~30-35 FPS) unless I pass the -O flag to python when running it (which gives me a smooth 60FPS). I'm planning on using cx_freeze to distribute it, but I need the -O flag to be used every time the game is run.
  Any ideas?</p>
