The header is qstring.h because it has always been qstring.h. That works in Qt 
1, 2, 3, 4 and 5, provided you have the right -I flags.

The novelty came from Qt 4, because you can include the class name without 
caring for which header it comes from. QString is not a good example, so I ask 
you: what header provides these?


Another thing came from Mac support: frameworks. Because in Qt 4 the one big 
Qt library was split into multiple libraries and each one is a framework, you 
need a two-level include to make it work with simple buildsystems:

	#include <QtCore/qstring.h>
	#include <qstring.h>

The latter only works if you add an -I to the Headers directory inside the 
QtCore.framework bundle. (Granted, recently the Mac OS X framework development 
philosophy changed, so headers-inside-frameworks is no longer recommended)

We don't want to manually maintain those headers. They change a lot during 
development. And we might accidentally forget an update before a release, only 
to see it reported as a bug with an angry "You don't do QA!" comment. So we 
wrote a simple script to do it for us.
