Command: {
	// Tasks specifies the things to run to complete a command. Tasks
	// are typically underspecified and completed by the particular
	// internal handler that is running them. Tasks can be a single
	// task, or a full hierarchy of tasks.
	//
	// Tasks that depend on the output of other tasks are run after
	// such tasks. Use `$after` if a task needs to run after another
	// task but does not otherwise depend on its output.
