--add-legend - include explanation of the symbols used
--add-omitted-headers - add a header stub for omitted foreign app

--omit - specify apps to be omitted in diagram
--include - specify apps to be included in diagram; other will be omitted
--headers-only - use only model header and relations, omit fields list
--url - generate URL to plantuml.com/plantuml/svg/YOUR_DIAGRAM
