I am providing that information not to copy the code but the idea (or I will 
just upload the dumped class file). And do you think "I want to run those 
wonderful OS X apps that is not limited to 'Apple-branded computer only' either 
right out of the box through Darling or after a recompile for those open-source 
projects on my Linux box", and "I want my next great Linux app talk to Macs in 
the language Macs speak (eg. Distributed Objects)" interoperability?

People reversed Siri to talk to their home automation systems and that is okay, 
now even if we are reversing Apple's Cocoa to make OS X apps run under Linux...
