-AFNetworking is a delightful networking library for iOS and Mac OS X. It's built on top of [`NSURLConnection`](http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/Foundation/Classes/NSURLConnection_Class/Reference/Reference.html), [`NSOperation`](http://developer.apple.com/library/mac/#documentation/Cocoa/Reference/NSOperation_class/Reference/Reference.html), and other familiar Foundation technologies.
