I somehow wound up owning python-sphinx_rtd_theme, I think probably because I was the first person to attempt to do a build that needed it. :-) Anyhow, I am not at all sure that I am competent to be the maintainer. I need some advice. There is a new upstream version available, 0.4.0. I am looking at it right now, and my attempts at unbundling fonts from this package seem to be unraveling.
Three font families are bundled: fontawesome, Roboto Slab, and Lato. We have all 3 of these in Fedora, but the problem is that this package wants the web versions of these fonts, too. We have fontawesome-fonts-web, but we do not have .eot, .woff, or .woff2 files available for the other 2 fonts, so far as I am able to determine. Since the .ttf files of those fonts are not byte-equivalent to the ones we ship ... I'm not sure what is safe to do here. I am not any kind of font expert.
Regards,
