+Tool Description
+================
+
+This tool helps with finding Qt4 tools and libraries,
+and also provides syntactic sugar for using Qt4 tools.
+
+The following snippet illustrates the tool usage::
+
+	def options(opt):
+		opt.load('compiler_cxx qt4')
+
+	def configure(conf):
+		conf.load('compiler_cxx qt4')
+
+	def build(bld):
+		bld(
+			features = 'qt4 cxx cxxprogram',
+			uselib   = 'QTCORE QTGUI QTOPENGL QTSVG',
+			source   = 'main.cpp textures.qrc aboutDialog.ui',
+			target   = 'window',
+		)
+
+Here, the UI description and resource files will be processed
+to generate code.
+
+Usage
+=====
+
+Load the "qt4" tool.
+
+You also need to edit your sources accordingly:
+
+- the normal way of doing things is to have your C++ files
+  include the .moc file.
+  This is regarded as the best practice (and provides much faster
+  compilations).
+  It also implies that the include paths have beenset properly.
+
+- to have the include paths added automatically, use the following::
+
+     from waflib.TaskGen import feature, before_method, after_method
+     @feature('cxx')
+     @after_method('process_source')
+     @before_method('apply_incpaths')
+     def add_includes_paths(self):
+        incs = set(self.to_list(getattr(self, 'includes', '')))
+        for x in self.compiled_tasks:
+            incs.add(x.inputs[0].parent.path_from(self.path))
+        self.includes = list(incs)
+
+Note: another tool provides Qt processing that does not require
+.moc includes, see 'playground/slow_qt/'.
+
+A few options (--qt{dir,bin,...}) and environment variables
+(QT4_{ROOT,DIR,MOC,UIC,XCOMPILE}) allow finer tuning of the tool,
+tool path selection, etc; please read the source for more info.
