def get(self, command_name):

overrides bzrlib.registry.Registry.get

Return the object register()'ed to the given key.

May raise ImportError if the object was registered lazily and there are any problems, or AttributeError if the module does not have the supplied member.

Parameters	key	The key to obtain the object for. If no object has been registered to that key, the object registered for self.default_key will be returned instead, if it exists. Otherwise KeyError will be raised.
Returns	The previously registered object.
Raises	ImportError	If the object was registered lazily, and there are problems during import.
	AttributeError	If registered lazily, and the module does not contain the registered member.

def register(self, cmd, decorate=False):

overrides bzrlib.registry.Registry.register

Utility function to help register a command

Parameters	cmd	Command subclass to register
	decorate	If true, allow overriding an existing command of the same name; the old command is returned by this function. Otherwise it is an error to try to override an existing command.

def register_lazy(self, command_name, aliases, module_name):

overrides bzrlib.registry.Registry.register_lazy

Parameters	command_name	The primary name of the command.
	aliases	A list of aliases for the command.
Unknown Field: module_name	The module that the command lives in.
