I'd like to note also that the epub is provided in the ‘releases’ section of that repo. Though some three images are missing from it (judging by the messages from pandoc).
I discovered that only after Homebrew installed two different versions of GHC taking up three gigabytes in total, and compiled `cabal-install` and then pandoc for five hours, with two gb of temporary files for 170 mb of output. Well at least I've taken this occasion to clean up some unused apps from the machine.
And speaking of modifications, it would be nice to have a version where the puzzles are one-click away from the section at hand. I keep feeling like I'm missing something. I don't understand why the puzzles are on their own page, let alone their own domain, so if I'm in a section and I want to do a puzzle I need to click back to the main site, click on the puzzle site, then find the equivalent chapter heading, and then dive into a puzzle.
