At [https://gitlab.kitware.com/vtk/vtk/-/blob/master/CMake/vtkModuleGraphviz.cmake#L1-7](https://gitlab.kitware.com/vtk/vtk/-/blob/master/CMake/vtkModuleGraphviz.cmake#L1-7) you are using a documentation style I don’t know. I know about CMinx which uses `#[[[... #]]`. I also tried doxygen but it seems not doable with doxygen. I wonder what you use here.

Doxygen. The filter [here](https://gitlab.kitware.com/vtk/vtk/-/tree/master/Utilities/Doxygen/filters) is invoked by the [doxyfile](https://gitlab.kitware.com/vtk/vtk/-/blob/master/Utilities/Doxygen/doxyfile.in#L102).

Indeed, it is just a crude script that strips out CMake to make it look like K&R C. The documentation renders “well enough” and allows us to cross-reference in the overall documentation too.
