Re: font copies in sphinx generated documentation

This is indeed a can of worms.

A previous discussion on the packaging list[1] concluded that, despite the common practice of packaging Sphinx-generated HTML documentation, there is probably no practical way to do so without running afoul of guidelines about bundled or precompiled JavaScript, CSS, and fonts.

Furthermore, Doxygen is just as bad.

I’ve been packaging PDF documentation instead, where it’s possible to generate it. This is probably OK, as long as you’re not worried about possible embedded fonts. Since I’m not aware of practical open-source tooling to detect and/or remove these; since a PDF that has essential external dependencies is frustratingly and almost uselessly non-“portable”; and since many LaTeX fonts don’t have OpenType versions that could be packaged as system fonts anyway: if embedded fonts in PDFs were an issue then it seems that packaging PDF files would be effectively banned in practice. I don’t think there’s been a substantial discussion on the matter, though.

Further clarity on some of these points would be welcome, although I’m personally *not* eager to put myself at the center of a debate about any of these issues.
