+  # The Windows job is a mess, but it's a mess with some advantages.
+  # The job is ran in a clean Docker container, and we have full control on
+  # the software present there. This also means that every single program
+  # needs to be manually installed, and since Windows doesn't have a
+  # package manager installing stuff in scripts is pure pain.
+  # Also, GitHub's support for Windows containers is really, really bad,
+  # and the only way of running a job in Docker is by passing everything to
+  # `docker run`, as a single cmd.exe command.
+  # Lastly, altering the PATH is almost impossible, and as far as I know
+  # the only thing that does that reliably is vcvars64.bat; so to make an
+  # executable available it is necessary to manually move it in a directory
+  # already in Path, like C:\vs\Common7\Tools\
