	"""
	:class:`Workflow` A Binary Ninja Workflow is an abstraction of a computational binary analysis pipeline and it provides the extensibility \
	mechanism needed for tailored binary analysis and decompilation. More specifically, a Workflow is a repository of activities along with a \
	unique strategy to execute them. Binary Ninja provides two Workflows named ``core.module.defaultAnalysis`` and ``core.function.defaultAnalysis`` \
	which expose the core analysis.

	A Workflow starts in the unregistered state from either creating a new empty Workflow, or cloning an existing Workflow. While unregistered \
	it's possible to add and remove activities, as well as change the execution strategy. In order to use the Workflow on a binary it must be \
	registered. Once registered the Workflow is immutable and available for use.

	Currently, Workflows is disabled by default and can be enabled via Settings::

		>>> Settings().set_bool('workflows.enable', True)

	Retrieve the default Workflow by creating a Workflow object::

		>>> Workflow()
		<Workflow: core.module.defaultAnalysis>

	Retrieve any registered Workflow by name::

		>>> list(Workflow)
		[<Workflow: core.function.defaultAnalysis>, <Workflow: core.module.defaultAnalysis>]
		>>> Workflow('core.module.defaultAnalysis')
		<Workflow: core.module.defaultAnalysis>
		>>> Workflow('core.function.defaultAnalysis')
		<Workflow: core.function.defaultAnalysis>

	Create a new Workflow, show it in the UI, modify and then register it. Try it via Open with Options and selecting the new Workflow::

		>>> pwf = Workflow().clone("PythonLogWarnWorkflow")
		>>> pwf.show_topology()
		>>> pwf.register_activity(Activity("PythonLogWarn", action=lambda analysis_context: log_warn("PythonLogWarn Called!")))
		>>> pwf.insert("core.function.basicBlockAnalysis", ["PythonLogWarn"])
		>>> pwf.register()

	.. note:: Binary Ninja Workflows is currently under development and available as an early feature preview. For additional documentation see Help / User Guide / Developer Guide / Workflows
