66 | Arrange the given list of classes into a hierarchy of nested lists. | |
67 | Where a nested list appears, it contains classes derived from the class | |
68 | whose entry immediately precedes the list. Each entry is a 2-tuple | |
69 | containing a class and a tuple of its base classes. If the <var>unique</var> | |
70 | argument is true, exactly one entry appears in the returned structure | |
71 | for each class in the given list. Otherwise, classes using multiple | |
72 | inheritance and their descendants will appear multiple times. | |
