+"""Tree builder compatibility suite.
+
+If you create a tree builder class, also create a test suite that
+subclasses this one. This test suite will parse various bits of
+well-formed HTML with your tree builder. Not every tree builder will
+handle bad HTML in the same way, but every builder should be able to
+handle _good_ HTML in the same way.
