Log message for revision 81945:
  Actually demonstrate the bug that Martian 0.9.2 fixes. The previous 
  test also worked with Martian 0.9.1, but this one doesn't as it's a pure
  doctest, which triggered the bug.

+Test grok_component() in an ordinary doctest.
+
+We already have tests for grok_component(), but these were placed
+inside a module. We will now test grok_component() in a pure doctest
+context. This used to demonstrate an error in martian when dealing
+with the __builtin__ module (fixed in martian 0.9.2).
+
+grok.testing.grok_component() can be used to grok individual
+components within a doctest, such as adapters. It sets up just enough
+context for some grokking to work, though more complicated grokkers
+which need module context (such as view grokkers) might not work.
+
+This defines the object we want to provide an adapter for::
+
+  >>> class Bar(object):
+  ...    pass
+
+This is the interface that we want to adapt to::
+
+  >>> from zope.interface import Interface
+  >>> class IFoo(Interface):
+  ...    pass
+
+This is the adapter itself::
+
+  >>> import grok
+  >>> class MyAdapter(grok.Adapter):
+  ...    grok.provides(IFoo)
+  ...    grok.context(Bar)
+
+Now we will register the adapter using grok_component()::
+
+  >>> from grok.testing import grok_component
+  >>> grok_component('MyAdapter', MyAdapter)
+  True
+  
+The adapter should now be available::
+
+  >>> adapted = IFoo(Bar())
+  >>> isinstance(adapted, MyAdapter)
+  True
