Here's how you use ReferenceDataManager

	ObjectId hierarchyId;
	var builder = new ChangeSetBuilder(objectFacade, null);
	{
	var hierarchy = builder.CreateHierarchy();
	hierarchyId = hierarchy.Id;
	var parentUnit = builder.CreateUnit("Parent", new Address("Lubicz", "23", "Krakow", "PL"));
	var childUnit = builder.CreateUnit("Child", null);

	builder.SetHierarchyRoot(hierarchy, parentUnit);
	builder.SetParent(hierarchy, childUnit, parentUnit);

Too much DRY

	public static T NullArgumentLogAndThrow<T>(this ILog log, T arg)
	{
	if (arg.IsNotNull()) return arg;

	// get calling method
	var ex = new ArgumentNullException(typeof(T).Name);
	log.Fatal(new StackTrace().GetFrame(1).GetMethod().Name, ex);
	log.Fatal(new StackTrace().ToString());
	throw ex;
	}

Branch switching script

	#
	# The script switches IIS web applications to point to some other directory. It is very usefull when frequently changing branches.
	# The script assumes SVN-ish branch structure like this:
	# Root
	# \|
	# \|--Branches
	# \| \|
	# \| \|--Branch 1
	# \| \|
	# \| \--Branch 2
