I've not have time to test this set, so just a quick report of a build error
related to this set after the fact.

I'm getting this error from "make SPHINXDIRS=tools pdfdocs":

Latexmk: Sometimes, the -f option can be used to get latexmk
  to try to force complete processing.
  But normally, you will need to correct the file(s) that caused the
  error, and then rerun latexmk.
  In some cases, it is best to clean out generated files before rerunning
  latexmk after you've corrected the files.
