I’m wondering if “rake freeze_gems” will freeze SwitchTower as well.
If it doesn’t, I could try to modify the rake task at  to freeze
extra gems such as switchtower into vendor/ (the rake task at 
freezes gems into lib/ which I disagree with).
Is there anyone else actually using a “frozen” SwitchTower? If so,
what did you do to freeze it with a minimum of fuzz?
