Doxyrest generates a decent overview even if a project has no Doxygen documentation comments at all:

AXL	sphinx_rtd_theme

Replace Doxygen with your own generator of Doxygen-compatible XML database and apply the same pipeline for documenting APIs in other languages:

Lua libraries

Doxyrest Lua API	sphinx_rtd_theme
Doxyrest Frame Settings	sphinx_rtd_theme

The above manuals were generated from Doxy-comments inside .lua files by using LuaDoxyXML instead of Doxygen at the first stage of the pipeline.

Jancy libraries

Jancy Standard Library	sphinx_rtd_theme
IO Ninja Jancy API	sphinx_rtd_theme

The above manuals were generated from Doxy-comments inside .jnc files by using the official Jancy compiler instead of Doxygen at the first stage of the pipeline.
