    Appify v5 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
    
    If you want to give your app a custom name, use the second argument:
    
        $Appify my-demo "This is my awesome DEMO"
    
    Once your app is created, $Appify will tell you the path to your Info.plist.
    You should customize the Bundle Identifier and Get Info String at least.
