Two minor things:

• Use .. MATH:: as we are trying to be consistent with the dev guide.
• I think "QQbar" should either be ``QQbar`` or the corresponding latex version.

Once fixed, you can set a positive review on my behalf.

I just noticed that you neither do detection of flint in configure or link to the flint library. Meaning that libpynac.so is actually underlinked. This may prove a problem for people using --as-needed in their LDFLAGS and the gold linker. See #20646 for a discussion of a similar situation.

The ticket is good to go for now but I will consider making a PR to solve these issues in 0.7.1.
