For those not aware what doxygen does, when devs insert doxygen markup in the code, it is parsed by doxygen and creates very nice output which give a very good overview of the code. For example, you can click on the file tree,and then click on a file, and you immediately get a view of all the cointaining functions and their description.
Example output, it happend to be in japanese, but you get the point:
The transition could be done gradually, and there could be an automatic cronjob that updated the documentation and made it available on a website. Now, puting in doxygen markup in all the code at once would be quite the big task, but if devs wanted, it could be done step by step.
Personally I think it would be more user friendly than browsing the code at github only.
Thoughts?
