Problems

1. Step 8 failed for me and it took me a while to figure out why. There were two problems to be fixed
   1. epdfinfo.exe was loading a library from git-for-windows and there was an error from this. To fix this I made sure the mingw libraries were ahead of the git-for-windows ones in my path like this

      (setenv "PATH" (concat "C:\\msys64\\mingw64\\bin;" (getenv "PATH")))
              

   2. The default encoding for newly created files was utf-8-dos, which uses line endings that epdfinfo doesn’t like. I originally had

      (prefer-coding-system 'utf-8)
              

      but needed

      (prefer-coding-system 'utf-8-unix)
