Regression Testing for Zope 2 support

>>> from epydoc.test.util import runintrospecter

We treat extension classes as if they were classes:

>>> from ExtensionClass import ExtensionClass

>>> runintrospecter(s='''
...     from ExtensionClass import ExtensionClass
...     ''', attribs='variables value pyval',
...     introspect='ExtensionClass')
ClassDoc [0]
 +- pyval = <extension class ExtensionClass at 40...
 +- variables
    +- __basicnew__ => VariableDoc for __basicnew__ [1]
    |  +- value
    |     +- RoutineDoc [2]
    |        +- pyval = <CMethod object at ...>
    +- __call__ => VariableDoc for __call__ [3]
    |  +- value
    |     +- RoutineDoc [4]
    |        +- pyval = <CMethod object at ...>

    |  +- value
    |     +- RoutineDoc [6]
    |        +- pyval = <CMethod object at ...>

    |        +- pyval = <CMethod object at ...>
    +- __reduce__ => VariableDoc for __reduce__ [11]
    |  +- value
    |     +- RoutineDoc [12]
    |        +- pyval = <CMethod object at ...>
    +- __repr__ => VariableDoc for __repr__ [13]
    |  +- value
    |     +- RoutineDoc [14]
    |        +- pyval = <CMethod object at ...>
    +- __setattr__ => VariableDoc for __setattr__ [15]
    |  +- value
    |     +- RoutineDoc [16]
    |        +- pyval = <CMethod object at ...>
    +- inheritedAttribute => VariableDoc for inheritedAttribute [17]
       +- value
          +- RoutineDoc [18]
             +- pyval = <CMethod object at ...>

(If we didn't add special support, ExtensionClass would be a GenericValueDoc.)
