Classes
=======

   (Many classes do not raise the proper NSExceptions yet.)

*NSArchiver::			[8]*
     	Doesn't yet call -awakeAfterUsingCoder:.

*NSArray::			[9]*
*NSAssertionHandler::		[9]*
*NSAttributedString::		[8]*
*NSAutoreleasePool::		[9]*
     	But not exception- safe

*NSBundle::			[8]*
*NSCalendarDate::		[7]*
*NSCharacterSet::		[8]*
     	decomposableCharacterSet and illegalCharacter set missing

*NSCoder::			[8]*
     	Missing class name substitution methods.

*NSConditionLock::		[8]*
*NSConnection::		[7]*
     	GNU Connection, however, needs:
          	

        * to handle retain/release/dealloc properly 	

        * to be integrated with NSInvocation 	

        * to incorporate futzing with low-level TCP-backend for better
          speed 	

        * to have UDP-backend work 	

        * to cache ConnectedCoder's for better speed 	

        * Thread-safety overhaul, this is major

*NSCountedSet::		[8]*
*NSData::			[8]*
*NSDate::			[8]*
*NSDeserializer::		[7]*
*NSDictionary::		[8]*
*NSDistantObject::		[7]*
*NSDistributedLock::		[7]*
*NSEnumerator::		[9]*
*NSException::		[9]*
     	But this needs integration with new, better

*NSFileHandle::		[9]*
*NSFileManager::		[9]*
*NSHashTable::		[8]*
*NSHost::			[8]*
*NSInvocation::		[3]*
*NSLock::			[8]*
*NSMapTable::		[8]*

*NSMutableDictionary::		[8]*
*NSMutableSet::		[8]*
*NSMutableString::		[8]*
*NSNotification::		[9]*
*NSNotificationCenter::	[9]*
*NSNotificationQueue::		[6]*
     	Needs integration with NSRunLoop, and efficiency improvements

*NSNumber::			[9]*
*NSObject::			[10]*
*NSProcessInfo::		[9]*
*NSProxy::			[7]*
*NSRecursiveLock::		[8]*
*NSRunLoop::			[8]*
     	NSTimer's not yet working, but everything else should be

*NSScanner::			[8]*
*NSSerializer::		[7]*
*NSSet::			[8]*
*NSString::			[8]*
     	Careful, relationship with GNU String is tricky; this could 	 also
     use fixing.

*NSTask::				[8]*
*NSThread::			[8]*
*NSTimeZone::			[8]*
*NSTimeZoneDetail::		[8]*
*NSTimer::			[6]*
     	Working out bugs with returning doubles.
