45# Disobedience can be built to a native OS X application. There are some
46# caveats:
47# - you will still need Fink (or something) for other libraries
48# - if you wanted an application bundle you are out of luck
49# - the menu bar is still in the main window (not at the top of the screen)
50#
51# So it's still rather rough and ready. But it does work...
