	* qt/dbusidl2cpp.cpp:
	* qt/Makefile.am: add the dbusidl2cpp tool, the replacement
	for dcopidl2cpp, found in the KDE installations (or the more
	modern kalyptus): generate Qt4 C++ code for the input XML
	introspection. Currently no IDL parsing.

+    The QtDBus IDL compiler is a tool that can be used to parse interface descriptions and produce

+    produce: the interface (proxy) class or the adaptor class. The former is similar to the
+    \ref StandardInterfaces classes that are part of the QtDBus API and consists of a single .h file,
+    which should not be edited. The latter consists of both a C++ header and a source file, which
+    are meant to be edited and adapted to your needs.
+
+    The \p %dbusidl2dcpp tool is not meant to be run every time you compile your
+    application. Instead, it's meant to be used when developing the code or when the interface
+    changes.
+
+    The adaptor classes generated by \p %dbusidl2cpp are just a skeleton that must be completed. It
+    generates, by default, calls to slots with the same name on the object the adaptor is attached
+    to. However, you may modify those slots or the property accessor functions to suit your needs.
