+To add this tool to your project:
+def options(conf):
+	opt.load('msvs')
+
+It can be a good idea to add the sync_exec tool too.
+
+To generate solution files:
+$ waf configure msvs
+
+To customize the outputs, provide subclasses in your wscript files:
+
+from waflib.extras import msvs
+class vsnode_target(msvs.vsnode_target):
+	def get_build_command(self, props):
+		# likely to be required
+		return "waf.bat build"
+	def collect_source(self):
+		# likely to be required
+		...
+class msvs_bar(msvs.msvs_generator):
+	def init(self):
+		msvs.msvs_generator.init(self)
+		self.vsnode_target = vsnode_target
+
+The msvs class re-uses the same build() function for reading the targets (task generators),
+you may therefore specify msvs settings on the context object:
+
+def build(bld):
+	bld.solution_name = 'foo.sln'
+	bld.waf_command = 'waf.bat'
+	bld.projects_dir = bld.srcnode.make_node('.depproj')
+	bld.projects_dir.mkdir()
+
+For visual studio 2008, the command is called 'msvs2008', and the classes
+such as vsnode_target are wrapped by a decorator class 'wrap_2008' to
+provide special functionality.
+
+ASSUMPTIONS:
+* a project can be either a directory or a target, vcxproj files are written only for targets that have source files
+* each project is a vcxproj file, therefore the project uuid needs only to be a hash of the absolute path
