Sen draws UML diagrams from HLA FOMs, or from STL. This is how the hla_fom example asks for one:
--8<-- "examples/packages/hla_fom/CMakeLists.txt:uml"That writes a PlantUML document. Running plantuml over it gives the picture, which for these
three FOMs is:
{ .on-glb }
You can open the image on a separate tab to get a better view.
