Installing Network Manager on Raspbian 2020-02-05

NOTE:
This guide was written more than two years ago, which in Pi years means it's now graduated college, or something. Inevitably, it's at least a little out of date, and it may even be entirely misleading. There are several helpful suggestions in the comments (thanks everyone), and most recently a report that what's here plain doesn't work on current (early 2022) Raspbian. Which isn't even called 'Raspbian' any more.
As of Jan 2022 I'm partially back in my office-which-has-access-to-eduroam, and I do have a need to build up a fresh Pi desktop. If and when I get that working I'll update this guide. In the meantime: good luck, and please leave a comment to report success or failure.
(June 2022) Nope, I still haven't actually tried any of this myself. However, I have had to troubleshoot eduroam wifi on my Linux ThinkPad. As of Ubuntu 22.04 it would no longer connect. [This Stack Exchange answer](https://askubuntu.com/questions/27976
