Comment (by rbeezer):
Some errors with building the HTML documentation follow. I think this is
from using intersphinx, but am not certain. Perhaps also related to the
`conf.py` files. I'll ping John Palmieri off-list to see if he wants to
take a look. On 5.10.beta2, but very similar behaviour on 5.10.beta4.
Two files in `devel/sage/doc/en/reference`: `conf.py` and `conf_sub.py`.
The first has a long list of top-level sections of the documentation. But
to my eye it seems we use the second and not the first (and setup patch
here also seems to reference the second).
I added {{{'matroids'}}} to the first and tried rebuilding (two passes).
Then tried rebuilding with
{{{sage -docbuild reference html -S -aE}}}
which my notes say will for a rebuild from scratch.
Here are the symptoms I'm trying to fix. Many many of these, and indeed
the `objects.inv` is not created for the matroids section.

I get about seven of these. Perhaps it is due to cdef'ed class
definitions. That is a guess. However, limited Googling suggests this
can be fixed with a proper `conf.py`, so maybe another symptom of the same
problem. For each file/module, it seem severe enough to keep the whole
module's worth of documentation from rendering at all - there is just a
title, and no real content.
