-// A smart pointer for CoreFoundation classes which does reference counting.

-// Manual reference counting:
-//
-// UInt32 someNumber = 10;
-// CFNumberRef numberObject =
-//     CFNumberCreate(kCFAllocatorDefault, kCFNumberIntType, &someNumber);
-// // do something with numberObject
-// CFRelease(numberObject);
-//
-// Automatic reference counting using CFTypeRefPtr:
-//
-// UInt32 someNumber = 10;
-// auto numberObject =
-//      CFTypeRefPtr<CFNumberRef>::WrapUnderCreateRule(
-//        CFNumberCreate(kCFAllocatorDefault, kCFNumberIntType, &someNumber));
-// // do something with numberObject
