Because I don't like Doxywizard and dealing with thousands of HTML files, I decided to make a ManiaScript reference generator that just requires to manually update the doc.h in the associated folders + the build version in the Doxyfile (PROJECT_NUMBER).
If there are new updates to Trackmania 2020, you can contribute by updating the doc.h in the associated folder and making a pull request.
For ManiaPlanet, it's no longer expected that the game will update.
The project includes the Doxygen Awesome CSS theme as submodule and is currently used for official builds.
