The plan is to eventually have enough time to pick through the file and make sure everything is actually up to date :).

From just a quick glance, here's a couple of the things that still need to be done:
- all of the external links should be checked for whether they are up to date (and still relevant to current Python)
- the 'Excursus: Setting environment variables' section needs a major overhaul ('autoexec.bat' isn't used (or at least not recommended) anymore, among other things)
