-=================
-Observer Registry
-=================
-
-Observer registries provide a way to register observers that depend on
-one or more interface specifications and provide (perhaps indirectly)
-some interface.  
-
-The term "interface specification" refers both to interfaces and to
-interface declarations, such as declarations of interfaces implemented
-by a class.
-
-
-
-  >>> from zope.interface.adapter import AdapterRegistry
-  >>> import zope.interface
-
-  >>> class IR1(zope.interface.Interface):
-  ...     pass
-  >>> class IP1(zope.interface.Interface):
-  ...     pass
-  >>> class IP2(IP1):
-  ...     pass
-
-  >>> registry = AdapterRegistry()
-
-
-  >>> class IR2(IR1):
-  ...     pass
-  >>> registry.lookup([IR2], IP2, '')
-  12
-
-  >>> class C2:
-  ...     zope.interface.implements(IR2)
-
-
-
-  >>> class IP3(IP2):
-  ...     pass
-
-Normally, we want to look up an object that most-closely matches a
-specification.  Sometimes, we want to get all of the objects that
-match some specification.  We use subscriptions for this.  We
-subscribe objects against specifications and then later find all of
-the subscribed objects::
-
-  >>> registry.subscribe([IR1], IP2, 'sub12 1')
-  >>> registry.subscriptions([IR1], IP2)
-  ['sub12 1']
-
-Note that, unlike regular adapters, subscriptions are unnamed.
-
-The order of returned subscriptions is not specified.
-
-You can have multiple subscribers for the same specification::
-
-  >>> registry.subscribe([IR1], IP2, 'sub12 2')
-  >>> subs = registry.subscriptions([IR1], IP2)
-  >>> subs.sort()
-  >>> subs
-  ['sub12 1', 'sub12 2']
-
-You can register subscribers for all specifications using None::
-
-  >>> registry.subscribe([None], IP1, 'sub_1')
-  >>> subs = registry.subscriptions([IR2], IP1)
-  >>> subs.sort()
-  >>> subs
-  ['sub12 1', 'sub12 2', 'sub_1']
-
-Subscriptions may be combined over multiple compatible specifications::
-
-  >>> subs = registry.subscriptions([IR2], IP1)
-  >>> subs.sort()
-  >>> subs
-  ['sub12 1', 'sub12 2', 'sub_1']
-  >>> registry.subscribe([IR1], IP1, 'sub11')
-  >>> subs = registry.subscriptions([IR2], IP1)
-  >>> subs.sort()
-  >>> subs
-  ['sub11', 'sub12 1', 'sub12 2', 'sub_1']
-  >>> registry.subscribe([IR2], IP2, 'sub22')
-  >>> subs = registry.subscriptions([IR2], IP1)
-  >>> subs.sort()
-  >>> subs
-  ['sub11', 'sub12 1', 'sub12 2', 'sub22', 'sub_1']
-  >>> subs = registry.subscriptions([IR2], IP2)
-  >>> subs.sort()
-  >>> subs
-  ['sub12 1', 'sub12 2', 'sub22']
-
-Subscriptions can be on multiple specifications::
-
-  >>> registry.subscribe([IR1, IQ], IP2, 'sub1q2')
-  >>> registry.subscriptions([IR1, IQ], IP2)
-  ['sub1q2']
-  
-As with single subscriptions and non-subscription adapters, you can
-specify None for the first required interface, to specify a default::
-
-  >>> registry.subscribe([None, IQ], IP2, 'sub_q2')
-  >>> registry.subscriptions([IS, IQ], IP2)
-  ['sub_q2']
-  >>> subs = registry.subscriptions([IR1, IQ], IP2)
-  >>> subs.sort()
-  >>> subs
-  ['sub1q2', 'sub_q2']
-
-You can have subscriptions that are indepenent of any specifications::
-  
-  >>> registry.subscriptions([], IP1)
-  []
-
-  >>> registry.subscribe([], IP2, 'sub2')
-  >>> registry.subscriptions([], IP1)
-  ['sub2']
-  >>> registry.subscribe([], IP1, 'sub1')
-  >>> subs = registry.subscriptions([], IP1)
-  >>> subs.sort()
-  >>> subs
-  ['sub1', 'sub2']
-  >>> registry.subscriptions([], IP2)
-  ['sub2']
