    Appify v4.1 for Mac OS X
    Creates the simplest possible Mac OS X app from a shell script.
    
    Takes a shell script as its first argument:
    
        $Appify path/to/my-script
    
    NOTE: You cannot rename appified apps, blame Mac OS X.
    If you want to give your app a custom name, use the second argument:
    
        $Appify path/to/my-script "My App"
