Agreed :-)

http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSPasteboard_Class/Reference/Reference.html#//apple_ref/doc/uid/20000328-SW13

It should be possible to build an app that uses the NSPasteboard using  
something like this:

NSArray *array = [pb types];
NSUInteger i;
for(i = 0; i < [array count]; ++i) {
   NSString *typestr = [array objectAtIndex: i];

   if([typestr isEqualToString: NSPICTPboardType]) {
     puts("PICT");
   }
   ...
}

Depending on how the NSString is defined in NSPasteboard.h for  
NSPICTPboardtype, we might be able to just print the typestr itself,  
and have it make sense.

Thanks for reminding me.  I'll increase the priority of this.
