How to use it

To include a PlantUML diagram, just wrap your definition in a "uml" code block. For example:

Text format uml:

Also you can put in your book block as

{% uml %}
@startuml

	Class Stage
	Class Timeout {
		+constructor:function(cfg)
		+timeout:function(ctx)
		+overdue:function(ctx)
		+stage: Stage
	}
 	Stage <|-- Timeout

@enduml
{% enduml %}

The block syntax also allows for a src attribute to import an external PlantUml file.

{% uml src="test.plantuml" %}{% enduml %}

Of course, you can also pass the parameters like this.
