Z d Z d Z d Z d Z e e e d d Z RS( s A class that registers objects to a name.
There are many places that want to collect related objects and access them
by a key. This class is designed to allow registering the mapping from key
to object. It goes one step further, and allows registering a name to a
hypothetical object which has not been imported yet. It also supports
adding additional information at registration time so that decisions can be
made without having to import the object (which may be expensive).
The functions 'get', 'get_info', and 'get_help' also support a
'default_key' (settable through my_registry.default_key = XXX, XXX must
already be registered.) Calling my_registry.get() or my_registry.get(None),
will return the entry for the default key.

:param key: This is the key to use to request the object later.
:param obj: The object to register.
:param help: Help text for this entry. This may be a string or
a callable. If it is a callable, it should take two
parameters (registry, key): this registry and the key that
the help was registered under.
:param info: More information for this entry. Registry.get_info()
can be used to get this information. Registry treats this as an
opaque storage location (it is defined by the caller).
:param override_existing: Raise KeyErorr if False and something has
already been registered for that key. If True, ignore if there
is an existing key (always register the new value).

None, get() will return the module itself.

a callable.

registered to that key, the object registered for self.default_key
will be returned instead, if it exists. Otherwise KeyError will be
raised.
