+Testing that grokcore multiadapters work under Zope2

+__init__():
+
+  >>> cave = Cave()
+  >>> fireplace = Fireplace()
+
+  >>> from zope import component
+  >>> home = component.getMultiAdapter((cave, fireplace))
+
+  >>> IHome.providedBy(home)
+  True
+  >>> isinstance(home, Home)
+  True
+  >>> home.cave is cave
+  True
+  >>> home.fireplace is fireplace
+  True
+
+This also works for named adapters using grok.name:
+
+  >>> home = component.getMultiAdapter((cave, fireplace), name='home2')
+
+  >>> IHome.providedBy(home)
+  True
+  >>> isinstance(home, Home2)
+  True
+  >>> home.cave is cave
+  True
+  >>> home.fireplace is fireplace
+  True
+
+Multiadapters that implement more than one interface can use grok.provides to
+specify the one to use:
+
+  >>> home = component.getMultiAdapter((cave, fireplace), name='home3')
+
+  >>> IHome.providedBy(home)
+  True
+  >>> isinstance(home, Home3)
+  True
+  >>> home.cave is cave
+  True
+  >>> home.fireplace is fireplace
+  True
