I notice a few problems with this:

1. The text on the title page runs off the right border.

2. The contents are blank and the indexes say "(Index is nonexistent)".

3. The inline links are all broken, e.g., "See ⟨undefined⟩ [Arithmetic], page ⟨undefined⟩."

I generated the PDF by running "make c.pdf" in a Docker container from this Dockerfile:

  FROM archlinux
  RUN pacman -Syu --noconfirm texlive-most ghostscript make

Did I somehow build incorrectly, or are these issues with the upstream repository?
